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
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.
