This was entered into an April Fools day contest. It's a MAGIC TRICK that you can purchase. It is not a downloadable app. It's simple to do for anyone 8 and up. This won't work unless you have the magic trick to make it work!
Tired of hearing about all the cool things the iPhone has / can do? Check this out... and the iPhone CAN'T do it! Using a regular deck of playing cards and an android device enabled with NFC, you can select a card from the deck and have it appear on the other person's smart phone by scanning their fingerprint that touched the card! Great brand new magic trick and super simple to perform. If you like this, visit http://smartphonecardtrick.com and learn more! This instructable shows you what each of the steps looks like. If you want to simply watch the video, you can do that here!
Using any barcode scanner you already have on your smartphone (or your camera if you don't have a barcode scanner) activate your app or camera and scan the back of your phone across the surface of the card box, so the camera can scan the fingerprint
Step 8: The Card You Selected Will Appear on Your Phone!
The NFC feature of your phone must be on but whatever card they select will appear on their phone! The barcode scanner scans the thumbprint on the outside box, and then scans down through all of the other cards, looking for a card that has matching prints. It then goes out on the internet and finds an image of the card that it thinks you selected, based on your fingerprints and and a bunch of other techie reasons and displays it on the spectators phone. You never touch their phone the entire time. They do it all themselves!
