Resolved Question: Can duct tape alone block RFID signals?
I have an RFID card that I use to unlock the front door of my apartment. The RFID still works last time I tried it, but the card was in rough shape. Since I have a spare I decided to look if I could move the RFID into something else so I wouldn't have to carry such a big card on my key chain. I peeled off the sticky half of the card and gently pulled the RFID chip and antennae off of the plastic card. I then laid it in the same shape (without breaking the wires) on the sticky side of a piece of duct tape. I then wrapped it in a few layers of tape. It's nice of nice, it's a lot smaller than before and now it's a little flexible, though I'm going to do something to make it less flexible. If you have experience with RFIDs can you let me know if there are any problems with my design? Do you think bending the copper wires will be a problem if they don't break completely? Could some chemicals in the adhesive cause a problem like corrosion?
