Greetings: There is so much good stuff on RF Cafe that there is no way to list or
link to all of it here. Please use the Search box or the Site
Map to find what you want - there is a good chance I have it. Thanks!
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.
