Why The iPhone 5 Killer Feature is Mobile Payments

Mobile payments are coming. The reality is, cash and credit card transactions are a wholly inefficient means of commerce compared to organized, trackable, digital payments; the problem is, nobody has a solution safe and sensible enough where people would be willing to throw their wallets away. Sure, there are mobile payments efforts like Jack Dorsey's Square, or Intuit GoPayment, but people are wary to jump into their solutions with both feet. Exchanging a bulky wallet for a sleek smartphone is a great idea, but there just isn't a solution that truly makes sense. Until now.

On March 6, the U.S. Patent and Trademark Office granted Apple a patent for a new technology called "iWallet," which is a digital platform that gives the user complete control over their subsidiary financial accounts directly on their iPhone, and also leverages Near-Field Communication (NFC) technology to complete credit card transactions on the phone as well. On Tuesday, more patents were granted to Apple in relation to the iWallet technology, including security measures that aim to keep financial information safe, and the app in iTunes that will house these features. In all likelihood, this is Apple's mobile payments solution intended for its next-generation iPhone, presumably called "iPhone 5."

People will say, "But I have a wallet. I don't need my phone to be my wallet." I'd also bet that 10 years ago, they didn't think they needed their phone to also be a music player, or a gaming device, or a Web surfing device. But now that it is, people can't live without any of it. Apple and Android have successfully killed the simple cell phone; now, it's a race to see who can pack the most features into a device that can fit in your pocket.

Apple breaks down the iWallet like this: Credit card transactions happen all the time, whether or not the cardholder is present. There's a lesser chance of fraud when the cardholder is present, but unfortunately, the cardholder can't be present all the time. Apple's solution, the iWallet, aims to provide real-time authorization for transactions where the cardholder is not present, or remote. However, unlike transactions over the Internet, Apple promises its service to be highly secure and reliable.

Since there are so many components to the iWallet, we're going to break them down and explain each of them.

Credit Card Profiles

When a user visits their profile in iWallet, they will see their available credit cards attached and be able to open up each individual card's "profile." Within the profile, users can view their monthly statements, read messages and alerts from the bank, and even adjust preferences or add additional cards. Within preferences, the owners can set payment alerts for days in advance, or let the user know when their balance is approaching the limit.

Parental Controls

Parents can be pleased to know that thanks to the iWallet, their children will be able to use their phones as digital credit cards, and thankfully, parents can set the restrictions. Under the parental controls within preferences, parents can set spending limits -- either per transaction or overall -- and can even restrict which merchants a child can purchase from. It's all done digitally in the iWallet.

When a child exceeds his or her monetary limit -- set by the parent, of course -- the transaction can then request an authorization from the parent (via their iPhone), or simply decline the request. It's extremely easy, and it gives total control to the parent to let them manage their family funds.

Authorization Requests

If you have a child or teenager that plans on making a lot of purchases, you as a parent may be receiving a LOT of iWallet Authorization Requests. To filter through all of these, Apple gives the cardholder several options, including automatic authorization for all missed requests, or just certain requests under a specific value, or just requests with a specific merchant, like Barnes & Noble or Apple.

Flagging Fraudulent Purchases

When a cardholder finds fraudulent activity on their account, it's always best to contact the authorities right away. Unfortunately, however, most people don't know their card has been stolen until they receive their monthly billing statements. The iWallet aims to give the user greater awareness of their transactions and facilitate contact with authorities when fradulent activity is suspected or found.

In iWallet, users will have the ability to "flag" any purchase, likely in the same way a user flags an email. When a purchase has been flagged, the cardholder's bank is immediately notified, and the bank will quickly get in touch with the cardholder to discuss the situation further and offer instructions. While there's no easy way to prevent theft, iWallet provides a great way to pounce on it as soon as it's happened and nip it in the bud.

The iTunes Hub
Since users don't want to handle all of their financial transactions on a tiny 3.5-inch iPhone screen, Apple's patent involves a new tab in iTunes called "MobilePay," which lets credit card owners see all of the credit cards in iWallet at a glance. Similar to the iPhone version, users can monitor their statements, bank messages, and recent purchases, and alerts and parental controls can also be set here too.

MobilePay will be an option you can toggle within iTunes once the platform becomes available. When you set up MobilePay, iTunes will ask cardholders to submit their credit card information, including their card number, name, address, and eligibility. At that point, you will be able to "sync" your credit card on iTunes to your iPhone, which will automatically push all of your data to your phone.

A New Mystery Gesture

Apple wants to make its payments platform as safe and secure as possible, so the company has reportedly added another way for users to approve their purchases. Instead of filling out a simple "CAPTCHA," iWallet will reportedly feature a brand new gesture, known currently only as a "Motion Based Payment Confirmation." One could only guess what the gesture will be. My money's on drawing a check mark with your finger.

Other Rumored Features in the iPhone 5

The next-gen iPhone isn't expected to launch until later this year, but that doesn't mean we can't daydream about what's inside. While little is truly known about the next iPhone, Apple loves to surprise fans with bold new features, and a number of recent reports and granted patents offer hints as to what we'll see come September or October.

LTE

The new iPad released on March 16 was the first iOS device to feature bands for the high-speed 4G LTE network. There aren't many sure-things when it comes to Apple, but it's a near-certainty that the next iPhone will similarly receive LTE capabilities.

LTE, or Long-Term Evolution, features significantly higher download and upload speeds compared to 3G technologies, but the current implementations of LTE in phones appear to cause "very short battery life," which is a "major complaint by users." If Apple wanted LTE in the iPhone 4S, it would have been forced to increase the phone's thickness to accommodate a larger circuit board and a bigger smart phone battery. Apple CEO Tim Cook, in a company earnings conference call in April 2011, said "first-generation LTE chipsets force a lot of design compromises."

"The iPhone 4 PCB [printed circuit board] is already incredibly small, not leaving any room for an extra chip to enable LTE without shrinking the size of the battery," said Anand Shimpi, a chip expert and CEO of Anandtech.

Fortunately, Qualcomm recently unveiled the fifth iteration of its new chip, which supports TD-SCDMA, TD-LTE, HSPA+, EV-DO, embedded GPS, and LTE on TDD and FDD networks worldwide. The chip works with Android and Windows 8 devices, but by targeting so many different carriers, there's a high degree of likelihood that this will be the same chip inside the iPhone 5.

New Shape and Form

As of January, Apple was reportedly gearing up to begin production on the iPhone 5. A source from within China's Foxconn manufacturing plant told 9 to 5 Mac that various sample iPhone 5 prototypes were floating around the floor, but there were a number of common features among the phones, including a display that measured at least 4 inches, and a longer and wider form factor that did not match that of the iPhone 4 or 4S. The sources added that all of the iPhone 5 prototypes retained the rectangular shape of the iPhone 4 and 4S, which would put to bed rumors of a thinner teardrop shape.

When many believed Apple would unveil an iPhone 5 in October, the Internet was flooded with photos of a thin, large-screen iPhone 4. The photos were widely believed to be doctored until one Chinese site discovered "mold engineerings" of an iPhone 4 with a noticeably larger screen. The renderings depicted an edge-to-edge design for the iPhone's screen, which looked to measure about 3.7 inches. Component industry trackers believed that the images represented Apple's wish to compete with rival devices with bigger screens.

Even though Apple released the similar-looking iPhone 4S, there's a possibility that this is what Apple had in mind for the iPhone 5, but without LTE, the iPhone 5 would not go into production anyway.

Patent: Shatter-Proof Glass

Besides the iWallet, the iPhone 5 may also include a number of the company's recently granted patents. One handy patent for the next iPhone could be Apple's crack-resistant glass solution, which places a shock mount between the glass and the body of the device that instantly inflates if the device senses it's falling, which is determined by the device's internal accelerometer. An actuator within the device then sucks in the cover glass as it accelerates to the ground, thus protecting it from damage.

Patent: Multi-Player Gaming

On March 15, the U.S. Patent and Trademark Office (PTO) published a patent application from Apple that describes a system for multi-player gaming. Similar to how the new Garageband's "Jam Session" feature allows groups of people to play different musical instruments together, the multiplayer gaming technology will allow groups of iPhone and iDevice users to play together, and even see the same game from different perspectives.

Believe it or not, the multiplayer game system mimics that of the "Find My Friends" app, in which a user's device detects other nearby devices that it recognizes as "friends," and invites them to all join a common application. The unique technology also determines the relative position of those devices, so some games -- like turn-based role-playing games or card games -- can be played in a specific order.

The crux of Apple's solution determines the relative position of many devices by taking pictures of a tag, and the system monitors those shared images and decides their relative positions. Apple's technology can define a position in two or three dimensions relative to the original tag, and by transmitting a positioning matrix to the other iDevices, the information creates a comprehensive map of the devices.

Once the order is set, the users can cooperate and play with each one another as content is simultaneously broadcasted and received on the iPhone. This can work for multiple players playing the same displayed content (ex: a racing game), or multiple users playing against each other in a game (ex: a hand-to-hand fighting game like "Mortal Kombat"), or multiple users taking turns to play the game (like a board game or "Jenga"). Virtual avatars even represent one's position by displaying the avatar from a different perspective depending on the position of the player relative to the tag.

Patent: The Photographer's Timer

Apple continues to improve upon the camera infrastructure in its iPhones, but as far as camera software goes, the iPhone has remained largely unchanged. That will change if the iPhone 5 includes the patent for a new iDevice self-timer, granted on March 8, which comes with a unique twist.

Traditionally, self-timing cameras are used to take pictures of a big group, or a self-portrait. But in Apple's self-timer, the camera will know that you are the "photographer" that also wants to be in the picture, and the iPhone will simply wait until it detects your face to take the picture.

"But what about interruptions? What happens if I get a call after I set the self-timer?" Wonder no more. If you set the timer and then your phone goes off, the timer will still wait until it has detected, recognized and verified that you are the photographer and that you're in place for the photo.

The smartphone industry's Achilles heel - Smartphone Battery life ?

Every few months, cell phones get faster processors, higher-resolution displays, and are infused with powerful new software. Indeed, these pocket computers are now more powerful than the hardware NASA used to send a man to the moon. So why is it, then, that the industry can't seem to make a lasting, reliable smartphone battery? Unless they're charged every eight hours, these $500 devices are worth little more than paperweights. Here, a guide to why cell phone batteries still underperform:

Why haven't batteries improved?

"The trouble with batteries, as everyone who makes phones will tell you, is that they don't follow Moore's Law," which posits that computing power will double every two years, says Farhad Manjoo at PandoDaily. That's because batteries depend on "ancient chemistry" that has already been optimized. New improvements "are mainly the result of power-saving techniques in the processors and operating systems that power our devices," not innovations in the battery itself.

How dissatisfied are customers?

Very. In a 2012 survey of 7,080 smartphone owners, research firm J.D. Power and Associates found that, while most users were happy with their mobile devices, battery life was named as "one of the few attributes that have declined greatly from previous years." Manufacturers have dramatically expanded these phones' lists of functions, but we barely have time, within one charge, to use them, says Matt Brian at The Next Web. Consumers are right, says MG Siegler at Parislemon. "I want a laptop that lasts for weeks on one charge. I want a cell phone that lasts a month." These aren't unreasonable demands.

Are new devices making things better?

They might actually be making things worse. Apple's new iPad, for instance, uses a super-fast 4G connection to allow battery-draining activities like face-to-face video chat, says Siegler. Faster, souped-up phones are battery killers, and Apple might even elect not to include 4G LTE on its next iPhone, says John Gruber at Daring Fireball. "It's only going to fly if Apple can figure out a way to maintain current (or better) battery life."

What's the solution?

No one knows. But whoever can solve the battery problem first will see "enormous gains," says Manjoo, "whether it's an incumbent phone maker or Ph.D.-laden start-up in a garage." Battery life - e.g. NOKIA BL-5C battery,LG LGIP-520N battery is the final hurdle to the mobile digital future we've been promised.

Digital cameras that run on AA batteries

Wishing you could find a digital camera that takes AA batteries? While most digital cameras use proprietary rechargeable lithium-ion batteries, there are a handful of models -- the bulk of which are from Canon and Fuji -- that still use standard AA batteries. But do you really want a camera that runs on AA batteries? Well, for one thing, using an AA-powered digital camera makes it easy to have spares along if you start running out of juice. But are there downsides? Sure. Let's dig in to get the full picture.

The pros and cons of AA batteries

AA batteries offer some conveniences that lithium-ion batteries don't. Cameras that take AA batteries work with rechargeable NiMH batteries and non-rechargeable alkalines, both of which are readily available at drug stores, supermarkets, convenience stores and elsewhere. While rechargeable AA batteries make more sense in the long run, in a pinch, you can always use alkaline batteries, which you likely already have around the house. Likewise, you can swap the same batteries between different electronics. Lithium-ions require a trip to an electronics store or shopping online, are pricier, and usually differ in shape from device to device.

Some downsides to using AA batteries are that you'll have to replace alkaline batteries rather frequently. If you use rechargeable AAs, you'll need to buy a separate charging station. The digital camera battery pack indicator will warn you when your batteries are low, but until then, you won't be able to tell how much power you have left -- something that's not an issue with lithium-ion batteries (think of the indicator on your cell phone or smartphone). AA batteries will generally slow down your shooting times, especially when using flash, and they are less resilient to hot and cold temperatures than lithium-ion. Lithium-ion batteries also generally have a longer life than AAs and discharge less over time.

Top AA camera picks

All of the cameras discussed here are either basic point-and-shoots or ultrazooms. Pentax's recently discontinued K-x camera was the lone DSLR that could run off AA batteries.

Canon offers a wide variety of cameras that use AA batteries, including the Canon PowerShot A800 (*Est. $80) and Canon PowerShot A1200 (*Est. $90) as well as their respective updates, the A810 and A1300. Canon's A series of cameras are geared toward entry level photographers, and as such are easy to use, with more automatic features than manual functions. Both the A800 and A1200 receive good reviews -- the A800, in particular for its low price and long battery life(other long battery life:Canon nb-4l battery,FUJIFILM NP-120 battery,SONY NP-FC10 battery.) (an estimated 300 shots on a set of standard AA batteries). The A800 lacks a viewfinder, a feature that the A1200, and the new A1300 both have, and are especially helpful for digital camera novices. Both the A810 (*Est. $110) and A1300 (*Est. $120) have a 16-megapixel sensor and 5x optical zoom. Reviews have not yet rolled in on these new models. Nikon offers just one camera -- the Coolpix L24 (*Est. $70) -- that takes AAs. The L24 is very basic and easy to use, but most reviewers recommend skipping it in favor of the Canon A1200 or other inexpensive point and shoots.

Fuji offers a handful of AA-compatible ultrazoom cameras, including the Finepix HS20EXR, FinePix S4000, FinePix S2950 and the yet to be released FinePix AX550. Fuji's rather large HS20EXR has a huge 30x optical zoom. "It looks like a DSLR and it feels like a DSLR," say editors at DigitalCameraReview.com. While editors like the image quality of the HS20EXR, they point to its bulkiness, slow startup time and autofocus issues as flaws. The S4000 is equally bulky, not a surprise since it also sports a 30x zoom lens, while the S2950 has 18x optical zoom. Image quality for both is just so-so according to reviews. The forthcoming FinePix AX550 is compact and features a much smaller 5x zoom lens. Canon also offers an ultrazoom model that takes AA batteries -- the 12x Canon PowerShot SX150 IS, though reviewers say its image quality and performance aren't the best.
