Which implant for work

I am looking to implant a chip in my hand in order to access the building at work rather than use my ID card that is based on the Mifare 4k IC.
The system uses the UID of the chip and the readers are set to 4k not sure if the 1k was programmed in. I am not looking to clone the chip as the implant UID will be used as an authorised user. However, I believe the 4k chip implant is not yet available. So what would be the best implant to buy?

Sorry we don’t have one at the moment that will work for you :confused:
