How does it work? You finish your meal at a restaurant, the bill arrives and you set your smart phone on top of it. An electronic transaction takes place, recognizes whether or not you are a new or returning patron, and if you are a frequent visitor it applies any available coupons or credits, pays the bill and downloads/saves any coupons available for your next visit. All this without your interaction, and no annoying check-ins needed. That was easy.
Although it has been in development for years and put into use in other countries, NFC is now rolling out with Android 2.3 Gingerbread on the Nexus S.
First there was the debut of the Bump Technology where you could 'bump' your cell phone with another (if you both have the app) to exchange contact data. Now Near Field Communication or NFC looks like it is poised to eclipse it already by eliminating the need for contact altogether and share data between cell phones--or other devices--within a 4" range.
Currently the Android 2.3 platform is the only one with the capability to use NFC but apps are already being written to capitalize on the possibilities and potential uses for this new-ish technology. Click here to see more.
Eventually this could serve as a secondary form of ID in some establishments where you are 'scanned' upon entry--wouldn't that make showings and open houses interesting?? You could instantly collect identification and contact information the minute a potential client walks into your listing; if they have NFC, and if they allow scanning.
The possibilities are endless. Click here or on the video below to see the Android NFC Demo.
