Handheld 125KHz RFID Copier for EM4100 and T5577

This handheld duplicator reads and writes 125KHz EM4100 EM410X compatible cards and rewritable EM4305 T5577 5200 EM4205 CET5557 tags. It operates standalone with no computer connection required. Two buttons control read and write functions with LED and buzzer feedback. The package includes ten rewritable keyfobs for immediate cloning tasks.

Ten Rewritable EM4305 T5577 Keyfobs Included

The bundle supplies ten rewritable keyfobs that accept new IDs over 20000 times. Random colours are shipped unless a specific mix is requested at order time. Each keyfob works with the duplicator to clone compatible 125KHz credentials. HID standard cards are not supported by this device.

Battery Powered Standalone Operation

The unit runs on two AAA batteries which are not included in the package. Insert batteries then press read to capture a source card and write to program a blank keyfob. The built-in antenna and indicators guide alignment. Only 125KHz formats listed in the specifications can be copied.

Questions about this item

How many times can the included 10 rewritable EM4305 T5577 keyfobs be cloned before they wear out?

Each keyfob supports over 20000 write cycles with different IDs, so the 10-pack gives you plenty of reprogramming headroom for access-control changes.

What is the practical read-range limit when duplicating 125KHz EM4100 or EM4305 cards with the built-in antenna?

The internal transceiver antenna requires close contact — place the source tag directly on the induction area for a reliable read.

How long will two AAA batteries last if the duplicator is used continuously all day?

The unit draws power only during active read or write operations; standby current is negligible, so a fresh pair of AAA cells typically lasts through many hundreds of clones.
