And it has a good sensitivity to a height of 25mmPackage includes:1 x RFID ReaderSketch for Arduino:// VCC----5V// GND----GND// RST----D5// SDA----D10// MOSI---D11// MISO---D12// SCK----D13#include #include RFID rfid(10,5); //D10--SDA, D5--RST unsigned char serNum[5]; unsigned char writeDate[16] ={'R', 'o', 'b', 'o', 't', 'D', 'y', 'n', '-', 'T', 'e', 's', 't', 0, 0, 0}; unsigned char sectorKeyA[16][16] = { {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF}, {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF}, {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF},}; unsigned char sectorNewKeyA[16][16] = { {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF}, {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xff,0x07,0x80,0x69, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF}, {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xff,0x07,0x80,0x69, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF},}; void setup(){ Serial.begin(9600); SPI.begin(); rfid.init();} void loop(){ unsigned char i,tmp; unsigned char status; unsigned char str[MAX_LEN]; unsigned char RC_size; unsigned char blockAddr; rfid.isCard(); if (rfid.readCardSerial()) { Serial.print('The card's number is: '); Serial.print(rfid.serNum[0],HEX); Serial.print(rfid.serNum[1],HEX); Serial.print(rfid.serNum[2],HEX); Serial.print(rfid.serNum[3],HEX); Serial.print(rfid.serNum[4],HEX); Serial.println(' '); } rfid.selectTag(rfid.serNum); blockAddr = 7; if (rfid.auth(PICC_AUTHENT1A, blockAddr, sectorKeyA[blockAddr/4], rfid.serNum) == MI_OK) { status = rfid.write(blockAddr, sectorNewKeyA[blockAddr/4]); Serial.print('set the new card password, and can modify the data of the Sector: '); Serial.println(blockAddr/4,DEC); blockAddr = blockAddr - 3; status = rfid.write(blockAddr, writeDate); if(status == MI_OK) { Serial.println('Write card OK!'); } } blockAddr = 7; status = rfid.auth(PICC_AUTHENT1A, blockAddr, sectorNewKeyA[blockAddr/4], rfid.serNum);
