Big fan of Tapsigners, we will be receiving a sample for doing dev work with, a reader and I think a couple of cards. The plan is to integrate it as a security UX boost for indranet relay operators and possibly building a release signing protocol tool built with it.

I believe that physical RFID signers will be very important going forward. Lots of ways to improve UX of cryptographic security protocols with one. No battery, just quick, easy signatures at the wave of a hand.
