I'll will report back as soon as I know if they work on TagIT transponders.

(It's been some time since I looked into 15693, so I might be wrong.)

It indeed seems to be using the ISO15693 standard, but with a dual subcarrier. From what I can see in the current proxmark's code, it's only supporting single subcarrier.

Not being a signal processing guy I'm not sure what need to be done to support dual subcarrier. I'll first need to learn some signal processing background I guess.

So I brought one back home to identify it. And it was a tag-it one (see http://www.dropbox.com/gallery/4064278/ … 9?h=ae1eb6). So, needless to say, it's my next target (after I complete the code cleaning I'm currently doing) smile

Secured chip from TI-RFID is name SpeedPass and has already been broken by students 2 or 3 years ago.
