mysterious DX "Programmable/Writable RFID keychain"

DealExtreme is selling a mysterious "Programmable/Writable RFID keychain" here, and there's some question as to what it actually is and/or if it's actually writable.

I bought one and read it with my PM3, and got the following sample trace ... anyone have any opinions on what it might be?

I stongly suspect you'll find it's a Q5 card.  You'll also find that Deal Extreme sells a 'cloner' to read EM410x cards and write to tags like this.

I've looked at a blank Deal Extreme cloner card and it's not a Q5 - no idea what it is, though! I'm planning to order one of these and sniff the commands sent to program it...

I've got one of the Deal Extreme cloners and card and had just presumed it's a Q5.

Worked like a dream to clone what I thought was one of my EM410x tags.

If I can find where I put my PM3, I could sniff the commands.
