I don't know about a "bit vector" but most NFC tags (whether type A, B, Mifare 1k/Ultralight/etc) all have a "UID". This is a unique identifier for the tag and what you're looking for.
But the tags you use will have to be of the 13.56 MHz hi-frequency variety. You won't be able to read most older HID Prox cards for example because they operate on the 125 kHz frequency.
