Free lifetime warranty


We know that you’ll love the protection given by Blockr Nano, but we also want you that we’re here to offer product support whenever you need it.

We include a free lifetime warranty for our Blockr Nano card, providing a free replacement if you accidentally damage your card. We also offer a no quibble 100% money back guarantee and free returns if you are unhappy with your card in any way.

Blockr Nano comes with full instructions which show you how to position the card in your purse or wallet. We also have a Youtube channel which shows you the card in action.

It's so thin!


As well as having twice the blocking range, Blockr Nano is also 40% thinner than any other card. That’s only slightly thicker than a credit card. This makes the card easier to add into your wallet and also makes it less bulky.

No batteries required – our card draws power from the credit card reader or scanner.

Your cards aren't safe


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

Card details can be stolen using a mobile phone, a portable payment terminal or a sophisticated high-powered scanner which can harvest hundreds of cards within minutes.

Positioning of cards

It works fine in my wallet but not sure about my wife's purse most of the cards are a staggered fit in her purse so they all won't line up properly haven't checked the operation on hers yet thanks stan

Blockr cards

My overall experience with your website was very good and the cards arrived within 2 days. I recommend this product to my older friends and I places another order for 4 more double packs of the contactless for them. They also are very pleased with them.
