Description: RFID读卡程序。硬件工作原理：基站在上电的情况下通过耦合线圈发射频率为125k的正弦波，ID卡的耦合线圈在125k的正弦波的激励下产生感应电动势，它为整个ID卡提供电源。ID卡通过调制电路根据其卡类的数据使ID卡的耦合线圈也发出正弦波，基站的耦合线圈接收到，根据它与125k波的不同来表示不同的数据。并将其通过DATA端以曼切斯特码的形式输出。-RFID reader program. Hardware it works: At the base station on the case of electricity through the coupling coil 125k launch the sine wave frequency, ID card at the coupling coil 125k inspired by the sine wave generated electromotive force sensors, which provide power throughout the ID card. ID card through the modulation circuit in accordance with its type of data card ID card issued sinusoidal coupling coil, the base station to receive the coupling coil, in accordance with the different wave 125k to express different sets of data. And Manchester, through DATA-side code in the form of output.

Description: This project aimed to develop a wireless system to detect and allow only the authorized persons. The system was based on Radio Frequency Identification (RFID) technology and consists of a passive RFID tag. The passive micro transponder tag collects power from the 125 KHz magnetic field generated by the base station, gathers information about the Tag ID and sends this information to the base station. The base station receives, decodes and checks the information available in its Database and Manchester code was used to send those information. The system performed as desired with a 10cm diameter antenna attached to the transponder. The Base Station is built by using the Popular 8051 family Microcontroller. It gets the tag ID and if the tag ID is stored in its memory then the microcontroller will allow the person inside.
RFID Reader Module, are also called as interrogators.
