The IB47 is a heavy duty MIFARE DESFire 4k Tag.

No Card number printed on the Tag.

The main characteristics of this credential are denoted by its name

"DESFire": DES indicates the high level of security using a 3DES or AES

hardware cryptographic engine for confidentiality and integrity protection

of the transmission data. FIRE indicates its outstanding position as a Fast,

Innovative, Reliable and Secure IC in the contactless proximity transaction

market.

Smart cards offer a high level of security and provide the advantage of

being multi-purpose. They function as proximity access cards, but since

they can store much more information they can also be used as cash

cards at company restaurants or vending machines, for example.

Compared to previous versions, the MIFARE DESFire EV3 chip can hold as

many different applications as the memory size supports and offers a

significant increase in operating distance and speed. MIFARE DESFire EV3

delivers the perfect balance of speed, performance and cost efficiency.

Installers can benefit from a secure card technology that can provide even

more functionality and protection when used with Vanderbilt VR series

card readers.
