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

I purchased this for the retenkess pin pad https://www.amazon.ca/Retekess-K10EM-W-Control-Waterproof-Waterpfoof/dp/B07QSFR4FFI use it for a garage door opener. It works perfectly!

Just as described, i've got them programmed very easily and i use them regularly without any problem.

Best deal I saw. Did not want that many, but most wanted just as much for fewer. Won't hurt to have extra.Work as they should, so what more would I need.
