Introduction
Castles Technology CA-CLM contactless reader module is based on RFID (Radio
Frequency Identification) technology and adopted HF (High Frequency) 13.56MHz
band to have the communication protocol ISO14443 type A, B standard to interact
the contactless smart card (a specified RFID tag) for specified applications like
payment control and scheme. The reader has a baseband processer to handle host
communication through RS232 interface, and to communicate RF analog front end
(RF band chip) through SPI interface. RF chip is charged of air interface protocol and
modulation to handle the communication with contactless smart card or so-called
RFID tag through antenna. When the reader is operating, RF energy is transmitted by
RF chip through antenna continually, and also the polling of response of card landing,
once card is close to reader antenna, card will be energized by reader antenna RF
energy, and responses to reader in specified standard for application required from
host. The reading or writing of card will be occurred frequently during card landing
on the reader. Also the indication LEDs and buzzer are included in this module for
application need. Following is a block diagram about CA-CLM contactless reader to
show the structure of RFID reader did.
