Carphone Warehouse has introduced a new mobile payments app powered by Simply Tap.

Once customers register for the app they can shop quickly with their payment details already saved by Simply Tap.

Staff at the retailer’s 800 stores will help shoppers sign up to the app and use its image recognition.

Using Simply Tap, consumers can shop from a marketplace within the app on their mobile phone or directly from any participating retailer using alphanumeric or QR codes and image recognition via an instant mobile checkout.

Simply Tap is an instant mobile checkout app developed by Mobile Money Network (MMN), chaired and backed by former M&S executive chairman Sir Stuart Rose. MMN has partnered with retailers including HMV, Thorntons and Pretty Green.

The Carphone Warehouse Mobile Checkout app will be available to a smartphone market which has 3.5m potential customers.
