125kHz RFID EM4100 USB Reader

This device reads 125kHz EM4100 RFID cards and tags for access control systems. It connects directly to a PC via USB and operates without an external power supply.

Questions about this item

What does the 106 Kbit/s communication speed mean when the reader is plugged into a PC?

It sets the maximum data rate between the reader and the host over USB, so card UIDs are sent at up to 106 Kbit/s once a tag is detected.

How does the USB interface limit the way this reader can be used?

The reader draws 5 V power directly from the USB port and needs no external supply, so it works only where a USB host or powered hub is available.

What physical space and mounting does the 9.8 x 6.3 x 1 cm black plastic unit need?

It fits in a 9.8 cm by 6.3 cm footprint with 1 cm height and weighs 70 g, so it can be surface-mounted or embedded in a panel with a small cut-out.
