Geak Unveils NFC Smart Watch and Contactless Ring

Geak unveils NFC smart watch and contactless ring - RF CafeYou have probably heard proposals for 'smart guns' that will only fire when owners wearing special rings are in possession. Here is a near field communications (NFC) ring that permits only its wearer to use a cellphone, tablet, or other NFC-enabled device linked to its code. Doing so eliminates the need to enter a password for access. According to an NFC World report, the ring contains an IC that can store personal contact information as well allowing the wearer to voluntarily "share" certain details about him/herself (why would you do that?) simply via proximity contact. Initially, the ring will only work with Geak's devices, but plans are in the works for more widespread adoption.
