The identification with RFID tag can be read the UID and identify it or
wrote the identification massages in the tag block then identify with the
block read. The UID identify was used in PCM-7130, because the UID is the
unique code with the tag in the factory programmed that had more security.

Figure 33. The two-tier identification Flow Diagram
The Figure 33 shows the flow diagram of two-tier identification which
has following step:
1. Initial PCM-7103 com2:
The default baud rate of RFID reader is 19200, the port com2 on
PCM-7130 is the connection port with RFID reader, therefore the com2
needs to initial to 19200, using the system call as following to set the com2
baud rate to 19200:
stty -F /dev/ttyS1 speed 19200
2. Read UID and password from MySQL via PHP script
