A playmate toy or similar children's toy is provided having associated wireless, batteryless ID tag that can be read from and/or written to using a radio-frequency communication protocol. The tag is mounted internally within a cavity of the toy and thereby provides wireless communication of stored information without requiring removal and reinsertion of the tag. In this manner, a stuffed animal or other toy can be quickly and easily identified non-invasively, without damaging the toy. Additional information (e.g., unique personality traits, special powers, skill levels, etc.) can also be stored on the ID tag, thus providing further personality enhancement, input/output programming, simulated intelligence and/or interactive gaming possibilities.
