If you would have followed my instructions above, you wouldn't need to disassemble it.yaconsult wrote:Thanks for this info. I had never disassembled it before but it was super easy - just needed the right size hex and screwdriver. Now I'll give all the contacts a good cleaning, put it back together and see if it makes any difference. I doubt that wearing of the contacts is the issue as the card was not inserted and removed that many times as I stopped checked the data often after a few months.archangle wrote:Dirt, oxide, or wear of the contacts is a possibility. If you can't get the reader out to clean it like palerider says, "deoxit gold" is one of the safer things to try. Put a little on the contacts on the card and swipe it in and out a few times. Don't try spraying it into the machine.
And, if you have an Infineer DT3500 card reader, I'd also use the method I suggested to clean those contacts.
