Tesco is poised to become the first UK store to launch electronic receipts next year.
Customers will have the choice of getting them by email rather than be given paper ones at the till.
The store is in talks with eReceipts which has run trials at Accessorize, French Connection and Monsoon. The technology can also monitor shopping habits and alert customers to items they may have forgotten.
The move towards digital receipts could sound the death knell for the till roll and cut back on 11.2 billion paper receipts Tesco prints out at the checkout every year.
Backed by eReceipts chairman, Lord Ian MacLaurin - former Tesco boss and Clubcard champion - the idea is set to take off in the New Year.
Lord MacLaurin told the English Newspaper The Mirror: “We started it two years ago and it is accelerating away. We’ve had successful trials and the future is very rosy. It’s very exciting.”
A spokesperson for eReceipts said: “We are talking to five big supermarkets. There will be an announcement after Christmas”.
