My leather bifold wallet with coin holder is starting to come apart at the seams. I'm not real interested in looks or name, but I've seen enough of the warnings about being able to read credit cards through unprotected leather that I'm considering paying the extra for that added protection. The problem seems to be that when independently tested, many of the advertised "RFID protected" wallets don't block electronic snooping well, just partially. Has anyone investigated this, and got some good answers? What I've read is the present RFID wallet blocking technology is still in it's infancy and needs more work other than a metal case?
