beberapa hari ini banyak posting tentang arduino + rfid + ektp buat login pc. tapi kali saya memanfaatkan idcard tempat saya bekerja untuk login dan logout windows.
langsung saja, kumpulkan material yang digunakan:
1. arduino pro micro
2. rfid RC522
3. id card yang ada chipnya. bisa pkai ektp atau emoney
4. kabel jumper
5. resistor 10k = 3 buah
wiring seperti dibawah ini:
wiring diatas saya modif dikit, 3,3v saya ganti vcc di pro micro
masukin library:
library
cek id number card dulu dengan upload sket dibawah ini:
#include <MFRC522.h>
#include <SPI.h>
#define SAD 10
#define RST 5
MFRC522 nfc(SAD, RST);
void setup() {
SPI.begin();
// Read a fast as possible. There is a limit for how long we are
// allowed to read from the tags.
Serial.begin(115200);
Serial.println("Looking for MFRC522.");
nfc.begin();
// Get the firmware version of the RFID chip
byte version = nfc.getFirmwareVersion();
if (! version) {
Serial.print("Didn't find MFRC522 board.");
while(1); //halt
}
Serial.print("Found chip MFRC522 ");
Serial.print("Firmware ver. 0x");
Serial.print(version, HEX);
Serial.println(".");
}
byte keyA[6] = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, };
byte keyB[6] = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, };
void loop() {
byte status;
byte data[MAX_LEN];
byte serial[5];
int i, j, pos;
// Send a general request out into the aether. If there is a tag in
// the area it will respond and the status will be MI_OK.

Serial.println("Tag detected.");
Serial.print("Type: ");

memcpy(serial, data, 5);

for (i = 0; i < 3; i++) {
Serial.print(serial[i], HEX);

for (i = 0; i < 64; i++) {

status = nfc.authenticate(MF1_AUTHENT1A, i, keyA, serial);
if (status == MI_OK) {
Serial.print("Authenticated block nb. 0x");
Serial.print(i, HEX);
Serial.println(" with key A.");
// Reading block i from the tag into data.
status = nfc.readFromTag(i, data);
if (status == MI_OK) {
// If there was no error when reading; print all the hex
// values in the data.
for (j = 0; j < 15; j++) {
Serial.print(data[j], HEX);
Serial.print(", ");
}
Serial.println(data[15], HEX);
} else {
Serial.println("Read failed.");
}
} else {
// If we could not authenticate with the A key, we will try
// the B key.
status = nfc.authenticate(MF1_AUTHENT1B, i, keyB, serial);

Serial.print(data[j], HEX);
Serial.print(", ");
}
Serial.println(data[15], HEX);
} else {
Serial.println("Read failed.");
}
} else {
Serial.print("Access denied at block nb. 0x");
Serial.println(i, HEX);
}
}
}
// Stop the tag and get ready for reading a new tag.
nfc.haltTag();
}
delay(2000);
}
setelah sukses upload, jalankan serial monitor baudrate 9600
tap id cardnya
akan muncul sperti bawah ini:

berarti idcard anda terdetek idnumbernya:
84, ED, DE, 1E
masukkan id number di atas di koding dibawah ini
source code:
sketch arduino
jangan lupa ganti id card
