Key Features

• • Frequency
    • 125 kHz (Low Frequency) — This frequency offers good read range (typically 2-10 cm) and works well near metals and liquids, though data transmission speed is slower compared to higher frequencies.
  •  Technology Standard
    • EM4100/EM4200 (or compatible) — These are the most common chip types for this frequency range. EM cards usually come pre-programmed with a unique 26-bit or 34-bit serial number (UID).
  •  Features
    • Contactless Operation — The card contains an embedded coil and chip powered by the electromagnetic field from the RFID reader, meaning no physical contact is required.
  • Read-only (RO) — Most EM cards are read-only, which means the UID cannot be rewritten. This makes them ideal for fixed identification purposes.
  • Durable and Lightweight — Made from PVC materials, they’re designed for everyday use.
  • Range — Typical read range is 5-10 cm depending on the reader’s power and antenna size.
  •  Dimensions: Standard CR80 size (credit card size): 85.6 × 54 mm, thickness ~0.76 mm.
