The Technology

What makes the difference in a Merlo wallet? These diagrams show how the magnetic field from the card reader interacts with different wallets. Merlo's patent-pending tech ensures only the cards you intend get read while the rest are safely secured.

Standard wallet

A standard wallet hardly affects the field. The high field strength all the way through the wallet means all your cards can get read all at once.

Shielded wallet

A shielded wallet stops cards being read inside the wallet, but also stops cards around the wallet being read.

Merlo wallet

Merlo wallets with patent pending technology are shielded on the inside but cards are still readable on the outside.

Works a treat indeed - used it on the Valencia tube Suzanne, London

The Smart Wallet

Two pockets for contactless card use

Use your two most frequently-used contactless cards separately in the outer pockets and place all your other cards in the inside.

It’s not just a shielded wallet

Our patent pending technology is selective – it blocks the cards inside the wallet while allowing cards in the outer pockets to be read. So you can be sure the right card is charged, every time.

Make payments on-the-go

Fast, easy & secure wiith the knowledge that your cards are safely inside your wallet.


Proudly designed in London for today’s demanding lifestyles. Made to last with a durable quality leather outer & hardwearing suede lining which lasts much longer than the usual silk or cotton linings.
