Making a RFID blocking bag

[pampam]

Can I line a belly bag with tinfoil and ducttape to block rfid technology? I see instructions on the web about making rfid blocking wallets, but I thought I could just turn an old bag inside out,use tinfoil and ducttape to make a bag. Any ideas?

Unfortunately, duct tape an aluminum foil no longer blocks modern RFID chips. It may disrupt transmissions, but not passive scans.

Copper mesh works, but it is price. You could also build a faraday cage with something like this:

also a bit pricey, but worth it.
