Er, what?

There's nothing in the announcement you forwarded to suggest anything  
more than run of the mill ISO 14443 passive RFID in the same ISO 7810  
ID-1 form factor as previous Harvard ID cards. Whence the notion of  
any on-card crypto whatsoever? Unless you know more than you  
forwarded, you're FUDing.
