* ------ [RFID1356_03] RFID Bus Example --------
*
* Explanation: This sketch shows how Libelium’s RFID/NFC 13.56 can be
* used for ticketing solutions, in this case we use the RFID/NFC to
* simulate a RFID access control inside a bus.
* First, we assignate a quantity of money to the card (with a secret
* password of course). After that, each trip will substract the fare.
* This can be also used for a gym or a parking, for example.
