Someone hack hacked their jailbroken iPhone to read RFID tags. I think this could be a great way for companies to use old iPhones as RFID readers for their warehouse. Smartphones are too valuable these days to be thrown away after use but turning them back into functional gadgets like this will be great for our environment.
I do remember at CES 2010 this year, they were using old, recycled Blackberries to read people’s tickets, that was a great idea.
The idea behind this project is to see what the iPhone’s serial is capable of and to try and have a little fun with RFID along the way. This reader works with the low frequency (125Khz) tags but I have a half working version for MiFARE Hi-Frequency as well.
