This is not a contactless device. It uses a common 1-wire protocol.

Re: How to copy TM button???

Some can, some can not.
Without knowing specifics it is hard to say.

Some systems use the UID which is hard coded during wafer fabrication. I'm not aware of mechanisms around this.

Worth mentioning that I have not spent any time researching this for years. I'm not an expert on the subject.

I copy them using the Smartcard Deluxe machine. there are other machines on the market that are cheaper and can copy them though.
RMX Labs in Russia make a few different ones and a google search will bring up some other machines out there.


Hardware: Proxmark RV2,  Elatec TWN4 dev kit / ACS ACR122U / IDTronic LF Reader / OmniKey 5321 / HT108 RW / Custom Read Write 125khz RW and a couple of other RW bits.
