Carriers and device manufacturers search longingly for killer apps, and it seems that one is just about upon us. One of the next big things may be contactless payments, the ability to use a cell phone or similar handheld device to pay for products and services without actually having to break stride, stop and authorize the purchase.

In late June, according to a piece at Ars Technica, the Federal Reserve said a purchase of $15 doesn't even require a receipt. The piece, which for the most part is a discussion of the considerable security ramifications of contactless payments, suggests that the category will get a big boost by the new, lower limit.

Contactless payments (or electronic wallets) will have a big impact on mobile device vendors. Of course, there is no shortage of drivers of cell and smartphones. The ability to use a phone to buy a CD or some groceries without stopping could make the mobile device category even hotter than it is today. In a press release that hypes a recently released report, Javelin Strategy & Research suggests that chips in mobile devices will spur 30 million additional users during the next half-decade.

If that's so, it seems that contactless payments could become a major feature - perhaps the major non-voice feature - of mobile devices, not a handy add-on that some envision today. Moreover, in a mobile device environment characterized by its fragmentation - there are dozens of features aimed at relatively small pockets of consumers and corporate users - its seems that electronic payment capabilities could be a core function available in a high percentage of devices. It could be a valuable horizontal, not vertical, feature.

The compelling nature of contactless payments is a subtext of this feature on Nokia, which is actively researching the topic. The company recently participated in a trial with Visa, Mastercard and AT&T in New York City and near-field communications - a key underlying technology for contactless payments - is being widely tested. Indeed, this piece, which comments on a white paper from Atos Origin, suggests that contactless payments are an increasingly big deal in Europe.

Contactless payments - the antecedents of which, by the way, are already widely used in EZPass and other "closed" systems - could be a big deal because of their ubiquity. Unlike downloading music or video, using a cell or smartphone to pay for small purchases is something that will appeal to a huge number of people. Device makers know this, and certainly are working on the logistics and, of course, all-important security safeguards.

Contactless payment is gaining traction in the United States and despite assurances from credit card providers, some fear the technology is not secure enough for widespread adoption. Read this summary and article from Ars Technica: http://www.itbusinessedge.com/item/?ci=30727

The laptop LCD module disassembly guide :
