Mifare DESFire cards and tags
 |
When fast transport of large amounts of data, a high security level for the stored information and multiple applications on a single card or tag are required, Mifare® is the technology of choice. Integrated Engineering offers three types of Mifare® cards and tags:
- Mifare® classic with 1K memory;
- Mifare® classic with 4K memory;
- Mifare® DESFire.
Mifare® classic features
Mifare® classic is characterised by its high data transaction speed. The Mifare® chip contains 16 or 40 separate sectors for storing information (depending on card memory). The first sector is typically used for storing directory information. The remaining sectors can be used for storing for instance access control or balance information. As each sector is locked with its own security keys, each sector can be used for a different application. The advanced security features prevent unauthorised reading of card data, brute force attacks and record and playback of transmitted data. Because of this Mifare® is exceptionally suitable for payment applications.
ISO 14443
Mifare® is an implementation of the ISO 14443A standard for contactless smart cards. Mifare® classic complies with level 3 of the ISO 14443A standard, DESFire complies with level 4 of this standard. For this reason, Mifare® cards can be read with every ISO 14443A compliant contactless smart card reader.
Cards
Integrated Engineering’s Mifare® cards comply with the ISO 7810 credit card size. The cards are of course very suitable for printing with text, a logo and/or a photo. If required the cards can be supplied with a HiCo magnetic stripe on the backside of the card.
Tags
The small size of the Mifare® transponder permits it to be used into tags. The black epoxy tags are very robust and have the advantage that they can be worn on a key ring. The tags are only available as Mifare® classic. Various other shapes and sizes are available upon demand.
