iPhone RFID Readers

RFIDs are popular and even though it’s easy to hack them, they are widely used in almost every Big store and in Passports. For those whoa re new to RFID: Radio Frequency Identification is a low-power, low-cost wireless technology that enables identification of objects (having tags) from a certain distance. The primary purpose could be to monitor various products in a store and prevent misplacing, and even thefts.

So why Build your own RFID reader? Well you can use it for 1,000 reasons. Say you want to track the stuff you often forget like your keychain, your gadgets (say iPod) or TV remote, tracking all of them could be snap with RFID.

Whatever is your case, here is a quick DIY tutorial to get you started:

This reader works with the low frequency (125Khz) tags but I have a half working version for MiFARE Hi-Frequency as well. To kickstart this porject you need some basic stuff like iPhone USB Cable, jailbroken iPhone, an ID-12 RFID Reader, ID-12 Breakout Board, Logic Level Converter and few other stuff to get them right.

DIY Tutorial

Method 2: Apart from this another developer had presented a cool demonstration of RFID on iPhone, check it out below:

Method 3: And in case you are no DIY biggie, there’s one that you can buy online and just plug and play: iCarte. iCarte connects to the dock connector port of an iPhone/iPod and enables it to to read and write RFID tags.
