But be aware - they are Gen1, i.e. they don't act with sensors which check for chinese magic commands.

Did notice that www.rfxsecure.com had several new fobs (did order Gen2 7bit and 4bit 4k fobs)

Beware!!!!

Got mine today and its kinda low quality.

Chip and antenna is loose inside and the plastic sides of the fobs are openish (not glued)

Did email them about this (will see what the solution is from rfxsecure is)

By the way:

Why it is just possible to restore a BLANK Mifare-tag/card with the Proxmark3?
Is it some kind of piracy-protection or something like that?

Don't hijack other threads. Instead open a new one.
