Three way RFID card protection


Add a Blockr Ultimate card to your purse or wallet to protect your card in three ways. The card includes a mesh to deflect a signal, a scrambler to disrupt signals and a repeater chip which makes a scanner believe it has found multiple cards.

The RFID card protector will protect any number of cards within 2.5cm of the front or back. Simply add to your wallet to protect!

Easy to test


To test your card, try using it the next time you are at the self-service checkout at the supermarket. When you are about to pay, hold the Blockr card above or below your credit card and tap the payment terminal. Either nothing will happen or an error will appear (sometimes the message “more than one card presented”).

Just don’t forget to pay before you leave!

Your cards aren't safe


Our video shows the three ways thieves can steal money from your card without you knowing.

Does what it should

the app for testing was not on the list as stated was told as my phone did not have the correct chip it would not show up on this list not sure this is right as normally all apps show up also could not register more than 2 items from the drop down box but when contacted the supplier they registered them for me
