XBT and Proxmark

Support
4

To change it to 134kHz you can do:
lf config H
That will let you do stuff like lf search and have it find the xBT.

However - you don’t need to do that. Just use:
lf fdx read
And that tells the proxmark you want to read an FDX-B tag.

In our experience, the biggest problem with the Proxmark was getting the antenna aligned correctly.

Edited to add: here’s the sort of output you’ll get from the Proxmark with xBT.

proxmark3> lf fdx read
