May 5, 2006 While RFID hasn’t exactly got a great name in some circles thanks to the technology’s capabilities becoming a threat to privacy, there are some people on the planet who just can’t wait for the technology to develop. Like Amal Graafstra f’rinstance. Graafstra heard about RFID being used to tag cats and dogs and decided he wanted to explore what was possible. He now has two RFID implants - a 3mm by 13mm EM4102 glass RFID tag in his left hand and a 2mm by 12mm Philips HITAG 2048 S implant with crypto-security features and 255 bytes of read/write memory storage space in his right hand. Getting implants meant there was no need to carry an RFID access card around and he could implement his own RFID access control systems instead of buying expensive off-the-shelf products. Amal has now built systems that enable him to access his front door, car door, and log into his computer using his implants, and has written a book called RFID Toys ($US$16.50 here) which details how to build these and other RFID enabled projects and produced a kit of the parts you’ll need (book and kit US$96.85 here).
