Handheld 125 kHz RFID Duplicator

The YINGHUA copier reads and writes 125 kHz EM4100 and compatible cards without a computer. It ships with five rewritable EM4305 T5577 keyfobs that can be cloned over twenty thousand times. Two buttons and built-in LEDs make standalone operation straightforward. Power comes from two AAA batteries which are not included.

Suits installers and hobbyists who need portable

Ideal for duplicating 125 kHz proximity cards and the supplied keyfobs in the field. Not for users who require HID-format compatibility, multi-frequency support or software-driven encoding. Not for projects that need encrypted or high-frequency credential handling.

Operates at 125 kHz only

The device reads and writes EM4100, EM410X, EM4305, T5577, 5200, EM4205 and 5557 formats. HID standard cards are explicitly not compatible. This single-frequency constraint decides whether the duplicator matches the target credential system.
