Cidron Slimline readers are versatile and can easily be configured to read up to two different card data objects and handles both 7-byte and 4-byte MIFARE UID's at the same time as well as MIFARE Random UID and 8 byte iCLASS UID. This means that you can read credentials from different populations and it also gives the possibility of, in a controlled manner, upgrading from less secure technologies to more secure applications like MIFARE DESFire.
