I want to be implanted (i know it’s obvious), by a nfc chip (to reduce the distance and avoid copy). My perfect chip will be :
* readable / writable (with security)
* flexible (if see the video, it seems to be more simple to read)
* compatible with mobile / a usb nfc tag reader
The question i’m sure you will ask me, what i want to store ? A string or at least an extremly long integer
Given your requirements, I would suggest the flexDF since it is read/write, flexible with great performance, is compatible with all ISO14443 reader/writer modules… and most importantly, the one thing you mentioned above which was “avoid copy”… which I assume you mean you want security. Well, the flexDF is the only NFC implant with DES, 3DES, and AES security options so far. VivoKey will be out in a few months as a private beta, but right now at this moment, the flexDF is the only implantable NFC transponder that meets your requirements.
VivoKey is a java card platform running JCOP 3. Normal java card development requirements are all that is necessary if you want to develop your own apps for VivoKey.
