All Implemented Interfaces:
Runnable
public class RFIDDevice extends JposDevice implements Runnable
JposDevice based dummy implementation for JavaPOS RFIDScanner device service implementation. No real hardware. All read data with dummy values, operator interaction via OptionDialog boxes.
Supported configuration values for RFIDScanner in jpos.xml can be used to set the corresponding property values:
  • CapContinuousRead: Can be TRUE or FALSE. Default is FALSE.
  • CapDisableTag: Can be TRUE or FALSE. Default is FALSE.
  • CapLockTag: Can be TRUE or FALSE. Default is FALSE.
  • CapMultipleProtocols: Can be set to any hexadecimal value between 0 and 7FFFFFFF.
  • CapReadTimer: Can be TRUE or FALSE. Default is FALSE.
  • CapWriteTag: Can be set to "RFID_CWT_NONE", "RFID_CWT_ID", "RFID_CWT_USERDATA" or "RFID_CWT_ALL".
  • RFIDScannerFileName: Name of the file that consists of RFID label specifications as specified below.
This simulator uses a file to receive the tags to be read. One line per read, at the end restart at line one. Line separator can be CR, LF, CR LF or LF CR.
Each line consists of pairs of hexadecimal values, where the first value of each pair represent a tag ID and the following value the corresponding userdata. Values are separated by spaces. An example:
00000001 123456789abcdef0 0000002 4142434445464748
00000002 3031323334353637 0000011 6162636465666768 00000055 5555555500000000
A file containing the above values would have the following effect:
  • The simulator will read two different labels, one with 2 IDs and one with 3 IDs.
  • The length of each tagID is 4 byte, data length has a maximum of 8 byte per tag.
  • The first tagID if the first label is byte[]{ 0,0,0,1}, the userdata byte[]{0x12, 0x34,0x56,0x78,0x9A,0xBC,0xDE,0xF0},
  • The last tagID of the last label is byte[]{0,0,0,'U'}, the userdata byte[]{'U','U','U','U',0,0,0,0}.
  • After the second read, the simulator reads the first label again.
