All,

Over the past 2 years i have had 3 Blue RFID Key Fob Tags fail on me. The serial reader i have will not read them, but will read all my other tags. I use them to control a door strike and them failing means the person is locked out, so it causes quite a hassle. I know these things aren't made to last forever but i didn't think these would fail this fast.

What am I to do if this keeps up and my 5 other key fob tags start randomingly failing?? :frown:

Thanks,
Rob

Rob, welcome to the forums! I apologize that your first post had to be a problem instead of a new project.

It sounds like you know they failed because you have other RFID Key Tags that work with the same system. Since you're going through a door to reach the RFID Reader I wonder if communication distance is a problem - some tags work up to 3" and others a bit less. I'd be curious if they work properly on the other side of the door, next to the RFID Reader.

I can't answer the question about "why" they fail because we don't manufacture them in Rocklin. I'd be speculating or I'd have to return them to the factory in China where they came from. If I can get them back from you I could probably get a failure analysis done.

If you'd like to receive some replacements, just drop me a PM with your shipping address and we'll have them to you by Friday.

Sincerely,

Ken Gracey

Ken,

Thanks for replying so quickly. I'v put the tags right up to the reader and it still shows no data for the 3 specific tags.
A failure analysis would be great. Have you or anyone ever heard of this happening to anyone else?

Thanks,
Rob

Hey Rob, couldn't get back to this thread quickly enough today. Anyway, I had some tags sent out to you a day or two ago.

For the failure analysis, I need the failed tags back to Parallax before Wednesday if possible. Our crew is going to China and they can meet with the supplier at the end of next week.

Thanks,

Ken Gracey
