Smart Card based PKI (Public Key Infrastructure)
.. used by eMails (S/MIME), data encryption and secure authentication (VPN, SSL/TLS). It is based on public/private keys (typically RSA) and certificates, which bind a user identity to a public key.
..the private key is often stored on a smart card..
The most common API to access cryptographic smart card functions is the PKCS#11 interface, published by RSA Labs.
..Corresponding to the PKCS#11 interface, the PKCS#15 specification defines a file structure and description syntax for keys and certificates on the smart card.

State Snooping aka "foiling scalpers"
A real-name ticket sales system began operation Sunday in Beijing. .., aims to make buying a ticket more convenient and fair, by foiling scalpers.
..a ticket vending machine particularly installed with an ID card reader

Odd DESFire Fact
When changing a Key on a DESFire SAM using AES
you can only do it once!
To change tha key again you have to restart the program.
Even an ATR does not enable that second key change..
So I wrote a "hot-swap" program which enables SAM change...
the original SAM can still only change a key once ...
There must be something in the Javax.smartcardio that gets initialized on program startup
which then only lets you change a key once!
