In one off-site location that I have to store a couple passwords, I use<br>
an NFC MiFare tag with a few kbytes of storage. The password is stored<br>
there encrypted and the tag can be hidden with no identifying markings.<br>
I did the same thing once with a paper one-time MARTA Breeze card. The<br>
card can be formatted and reused as a blank storage card but it only has<br>
about 64 bytes of storage.<br>
<br>
Granted you need an NFC reader to pull the data off but it's not obvious<br>
what the tag is because the generic MiFare card is just a piece of white<br>
plastic.<br>
