HENAXSAD HERNAS RFID Reader Writer Duplicator, Multi Frequencies RFID Smart Card Programmer, Encrypted Card Decoder, with Writable Key Fobs Cards, Free Software (Only for Access Control Using)

Included dual frequency fobs does not work with my original fob. Had to buy T5577 125KHz cards. Works well but did not expect that I have to spend more money to buy the fobs / cards.

I have a need to duplicate/copy access control key fobs. Search around a bit and settled on this unit.This unit is typical of many others with similar, if not identical, functionalities. Most of these units are made in China with simple Chinese and English interfaces. Many access control units here in the U.S. are 125Khz units. While more advanced access control units and most systems based in Asia are 13.56Mhz units. Your office/apartment typically provides one keycard/keyfob. If you need to duplicate the keyfob, this unit will work. I've tried both 125Khz and 13.56Mhz without issues. As long as you have the original, this unit can write/copy the same UID to another keycard/keyfob allow you multiple access cards/fobs.The copying process is quick and simple by "reading" from the original and "writing" to the copy. This unit works well for my purposes and come with 10 dual frequency key fobs as a bonus. All in all, works as expected.

Can duplicate even encrypted 13.56Mhz fobs using PC.

Don't waste your time or money, doesn't really do anything, their customer service is a joke, and the seller is not helpful either. Overall it was a waste of time and money.

El producto tal vez sea bueno, pero no tiene un manual de instrucciones de uso ni en el código QR , ni en Youtube ni en internet. Es decir no se sabe cómo usar ni cómo hacerlo funcionar. Por eso lo devolví. Nunca copio nada.
