How would i go about making an RFID triggered beep/LED Flash?
Ive bought a RFID dongle and tablet to work together for me as a loyalty data collector. The thing is, when the Milfare 1k card is scanned, it wont make a beep or LED flash to let the customer know its been scanned correctly.
I need another reader which is connected nest to the dongle (all of this will be put together in a plastic compartment) so that when any Mifare 1k card is scanned the dongle and tablet will do its job but i want the other scanner to let off a beep and LD flash at the same time?
How would i go about doing this??
