Concept
Passive tags harvest energy from the reader’s field and reply with a UID (and optional memory).
A little theory
ISO14443A MIFARE Classic 1K is common in Indian kits — fine for classroom UID demos; not high-security. In the classroom, treat MIFARE 1K RFID Cards + Fobs Pack (10) as a beginner part using 13.56 MHz tag. Typical India street price is about ₹80–₹200. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
Tap on RC522; print UID; store allow-list in EEPROM/SD.
