These Silvery Horizontal RFID Blocking Card Sleeves keep all your 13.56 MHz RFID-enabled cards (i.e. credit cards, bank cards, photo IDs, etc) safe from identity theft and are much more effective than wrapping them in aluminum foil. These protect your cards' Radio Frequency Identification (RFID) chip from getting accessed by an uninvited, unauthorized, potentially nefarious RFID reader.
One single sleeve is 65mm x 90mm. Fits perfectly in your wallet or purse. Comes in a pack of ten, so it's ok if you lose one or give away one to a friend
Not good for 125KHz blocking - usually door-access cards use this frequency.
