Touchatag (formerly TikiTag) is a very interesting looking consumer-level RFID (radio frequency identification) product. They can be used in many ways, from toilet paper inventory control to managing your Airwolf VHS tape lending library. I plan to get one soon to test out and do a proper review. (It probably won’t displace my iConveyor as my favorite RFID device!)
MAKE pal Kent Barnes send these photos of the device’s innards for us all to enjoy. Note the SIM card; what’s that doing there?
