> Multi-sector authentication, multi-block read and write
> Anti-tear function for writing AES keys
> Keys can be stored as MIFARE CRYPTO1 keys (2 x 48 bit per sector) or as AES keys (2 x 128 bit sector)
> Supports virtual card concept
> High data rates up to 848 kbit/s
Security levels
MIFARE Plus cards support four security levels (0 through 3) as described below. Cards operate in one security level at any given time and can only be switched to a higher level.
An automatic anti-tear mechanism is available for secure deployment of rolling keys. If a card is removed from the field during a key update, it either concludes the update or automatically falls back to the previous key.
MIFARE Plus is available in the proven MOA4 module and as sawn bumped wafers, so no changes need to be made to existing manufacturing processes. For benchmark security on the reader side, the MIFARE SAM AV2 (secure application module) is available. The Common Criteria 5+ certified IC includes all MIFARE Plus commands, secure key storage and AES calculation for a reader device.
To support the design-in process for reader manufacturers and solutions developers, NXP has MIFARE Plus documentation, application notes, and software toolkits available.

The Packers NFC CARD will be in their 2010 Bye Week enjoying the first place (6-3) of the NFC North, and you will be back on the road to check out the Minnesota Vikings, a team against which they began their 3 win strike on Week 7. Aaron Rogers is following latter seasons line, and has already 2,300 yards for 15 touchdowns. Greg Jennings can also be doing his thing, and has already surpassed the 4 touchdowns from last season with 6, and is also coming closer the fir,000 yards with 551.
