Similarly like every system has its hierarchy, even in the RFID can be found simpler but also more sophisticated technologies. DESFire EV1 working at the 13,56 MHz frequency belongs to a top in an RFID, that´s why it can be found mainly in payment systems, public transportation and other areas, where fast read/write on the card, various applications on the card and mainly highly secure communication are beneficial. An advantage of the system is also its anti-collision design - important in the case, when several cards are in the range of a reader. Relatively big memory (2, 4 or 8 kB) enables to store a considerable amount of data in various files. DES/2K3DES and mainly 3K3DES and AES encrypting algorithms takes care for a secure communication.
New DESFire cards in our portfolio DESFIREEV14KISO and DESFIREEV18KISO are suitable for all MIFARE®/DESFire readers like for example SL040A. For a full usage of cards potential, it is necessary to use a device able to read but also to write, like for example SL032 and SL500A-USB. . Many useful information can be found at www.mifare.net.
Selected types are already available directly from our stock, upon request we´re able to provide you with any other RFID component within few days. In case of interest, please contact us at info@soselectronic.com.
