There is no indication that a card has been read when being presented at a Security Expert Smart Card Reader.
Security Expert Smart Card Reader (SX-DRD-??, SX-DRK-??, SX-RD-??, SX-RK-??)
Reader is configured but there is no LED activity or beep when a card is presented at the reader.
- Wrong technology, eg trying to read a 125khz card on a 13.56mhz reader will not work and vice versa
- The card is encoded with a proprietary format/encryption
- The card is encrypted and the encryption keys are not programmed into the reader (note that this is different from the above, there are many scenarios where cards are encrypted but not proprietary and therefore if the encryption keys are programmed into the reader it can be read)
