Tesco is to introduce mobile checkouts to many of its Express formats after testing the devices at a handful of stores.

The grocer has been piloting the checkouts during busy seasonal times such as Easter and Mother’s Day. They can be wheeled out when trade is busy without occupying valuable space that could be used for products.

A spokeswoman for Tesco said: “The checkouts allow the stores to cope with busy periods without taking out stock to put in another permanent desk. They have been tested successfully and are now going to roll out to stores for busy periods such as lunchtime.”

The world’s third-biggest grocer has about 810 Tesco Express stores and has ambitions to open at least 150 more this year.
