The RFID Card 125kHz is a low-frequency passive RFID card in standard PVC credit-card form factor that operates at 125kHz — the same frequency used by the EM-18 RFID reader module — storing 330 bits of data and rated for more than 100,000 erase and rewrite cycles, making it a durable long-life card for access control and identification systems that require cards to be reprogrammed multiple times over their lifespan. This rfid card 125khz is distinct from the 13.56MHz IC card in both frequency and compatible reader type — it works with 125kHz LF readers such as the EM-18, not with 13.56MHz HF readers such as the PN532 or RC522.
The rfid smart card’s white PVC body is the standard flat access card form factor found in office buildings, apartments, and institutions across India, fitting standard card holders and badge slots without any modification. The 125khz rfid card’s operating temperature range of -20°C to 60°C suits indoor and outdoor installations where temperature variation may affect card reliability. The rfid card reader compatibility with EM-18 and other 125kHz readers makes this card the natural companion purchase when ordering an EM-18 module for an access control build. Available from StemVolt. This rfid card is ideal for EM-18 125kHz reader access control and Arduino RFID project.
