To remove the back glass panel on the iPhone 4, check out iFixit's video guide below. But they claim that the normal iPhone back piece should work just fine. In the above image, you can see they used a transparent back, so you can see where it's placed. They just cut the card to the size and shape they wanted, making sure NOT to harm the wireless data chip inside, and popped it in the back of their iPhone 4. Unplggd used a single Tap & Pay card from Bank of America that uses Visa's payWave technology. Unplggd has the full instructions for turning your iPhone 4 into a payment machine!īasically, if you have a bank card with an RFID or NFC chip in it (chances are you do), then the process is simple. But if you don't want to wait to use your iPhone to make 'tapping' credit card payments, then you don't have to. It's even possible that the new iPhone 5 from Apple will be equipped with NFC technology. Please enable JavaScript to watch this video. Even point-of-sale giant Verifone is hard at work updating all of their POS terminals for functionality with NFC devices. And PayPal has already unleashed its PayPal Mobile platform that uses NFC for making peer-to-peer transactions by just tapping devices (see the video below, demoed with Google Nexus S phones). Google Wallet is coming soon for most Android phones, as well as other options for paying with your NFC-enabled device. And thanks to NFC inclusion on smartphones like the Google Nexus S, people can now ditch their plastic and pay directly by tapping their cell phone to an NFC reader at stores. Most card providers have already switched over to NFC or plan to in the near future. The big difference is that RFID is capable of accepting and transmitting data a few meters, while NFC is restricted to a short range of about ten centimeters, making NFC a better bet for keeping your finances safe from hackers. But soon 'contactless' payments will be made by an entirely different beast- NFC, which stands for near field communication.Īctually, RFID and NFC are pretty much the same thing.

Remember the good ol' days when you actually had to swipe your credit or debit card to make a payment at the store? Now all it takes is a flick of the wrist to purchase goods with your card, thanks to RFID (radio-frequency identification) technology from Chase ( blink), Visa ( payWave) and MasterCard ( PayPass).
