RFID CARD / JAMMER OR BLOCKER - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Real easy question,

is there anything that can distort, block or jam a the RFID chip inside credit cards?

I know that many conductive material can shield the radio signals, but i am looking for some kind of super blocker or jammer that i don't have to wrap each card in it. I want something that i can place in my wallet or bag and it will be able to block RFID scanners from getting my card signals.

Thanks for the help, any ideas will be deeply thanked!
