computers that can make use of it.
The appearance of RFID module included three parts in this thesis.
They are RFID board, an antenna and RFID tag. The following figures show
the appearance of RFID module.
Figure 10. The Appearance of RFID module
1. RFID board: The RFID board would read the RFID tag, into digital
information to host via RS232. The specifications of RFID board in this
thesis shows as following:
Frequency : 13.56MHz
Tag : ISO15693
Interface : 3-wire ( CMOS,TTL )
Baud-Rate : 19200, 8, n, 1 (default)
Power Supply : 5V / 200 mA (max)
Standby current : 5V / 300uA
Operating Temperature : 0 ~ 60 °C
Operating Range : 6cm (Avg.)
Mechanical Dimension : 30.0(L) * 28.0(W) * 8.7(H)mm
2. Antenna: The more bigger size of antenna can increase the sense
distance of the RFID searching the tag, the features are:
Antenna : 50Ω
Mechanical Dimension : 30.0(L) * 28.0(W) * 8.7(H)mm
