Idesco have begun adding an anti-collision ability to both their Wiegand and OSDP versions of 8 CD 2.0 DESFire readers, letting them read multiple cards simultaneously. This is particularly convenient when one presents several cards or hybrid cards together.
This is because this new anti-collision ability ensures the reader won’t stop upon reading the first card it encounters, ignoring others in the detection zone – even though that first one wasn’t what one wanted to read. Now, 8 CD 2.0 can automatically scan all cards in its polling zone, detecting the one intended, making transactions faster, more convenient.
Additionally, 8 CD 2.0 now comes equipped with a more efficient process for reading one’s MIFARE Classic cards. 8 CD 2.0 will now only read an assigned sector, for improved security and faster transactions.
