Important note for customers: Our standard 125kHz copier works reliably with EM4100 and some basic HID/AWID cards (typically 26‑bit open format). However, many HID and AWID cards use proprietary encoding, longer bit lengths (37‑bit, 44‑bit, etc.), or encryption (e.g. Corporate 1000), these cards cannot be cloned by any generic low‑cost writer. If your card fails to copy, it does not mean the copier is defective – it means your card has advanced security features that require specialized equipment.
