Class ReadMFTag

java.lang.Object

org.posper.tpv.panelsales.TagReaderEvents

org.posper.tpv.util.ReadMFTag

All Implemented Interfaces:

gnu.io.SerialPortEventListener, EventListener, TagReader

public class ReadMFTag
extends TagReaderEvents
implements TagReader, gnu.io.SerialPortEventListener

This tag reader handles the Mifare protocol GinaPlus which is e.g. implemented on the RFID reader Promag PCR310. Mifare cards operate on the 13.56 MHz Mifare Standard (ISO14443-A). The cards are writable and can restrict access using keys. It is possible to communicate with more than one card in reach at the same time. A single card is identified by a factory id which can not be altered. In the current tag reader implemetation the factory id is used as card id. Since this id is only 4 byte long it might be possible to have duplicates. Later we will provide creating a UUID on the card as well as storing other information like customer name etc. Also, a secured value block can be implemented to hold an amount on the card which can be incremented and decremented. This allows using Mifare cards as prepaid cards without connecting to a payment gateway.
