The RFID tags I'm interested in do not have to have many bits. An 8-bit system is probably sufficient. RFID's in the market today have substantially more information as they are used to tag huge numbers of objects. What I do want is a thin, passive RFID tag which has a range of about 1 m. The goal is to have some sort of doorway, which will trigger an alarm if a child leaves without proper (parental) authorization. Oh, and the tags don't have to be writeable, read-only is good enough.
Here's an interesting thread.
