1.2. RFID Card Reader Functionality BLK 100
The BLK 100 is a RFID card reader. It can be used to pay with a
preformatted RFID tag.
The serial interface between the BLK 100 and the machine controller
transfers the price to charge to the BLK 100 and the price is deducted
from the Pay Key upon presentation. The machine gets told the successful
payment via serial interface.
1.3. Payment with the Pay Key
Only Pay Keys with personalisation matching the personalisation of the
BLK 100 are accepted.
Upon presentation of the Pay Key in front of the key fob reader BLK 100
the price received from the host is deducted from the Pay Key. Then the
according information is transmitted via the serial interface to the
machine.
When a suitable “Pay Key” is presented the red LED is switched on briefly
and once the amount has been deducted from the key fob the green LED
flashes 5 times.
