Pret A Manger has become the latest company to adopt contactless payment systems. The high-street sandwich chain is to launch the integrated system following a successful seven store trial in London. The system allows customers to pay for items totalling £10 or less by swiping their card across a contactless reader, and has been designed to save customers time and cut queues. It will be rolled out across Pret’s remaining 171 stores and the process is set to be complete by April 2009.
