YARONGTECH 125khz key fob, access rfid tag em4100 chip for access control (pack of 10)

9 out of 10 worked fine. One was d.o.a. okay for the price. Satisfied with my purchase

Did not work for our RFID needs. I loved that they were green, but that does no good if it doesn’t work.

These do not work. The seller refunded the money and didn’t want the junk back

Arrived quickly and look good.

All tags have a unique serial number (no duplicates) which matches what I get from the reader.

Lighter then other brands I have bought before, and works great with the sureflap/surefeed pet dishes
