The growth of QR (quick response) codes on product packaging is now leading to stores installing wifi free of charge for customer use so that their clients will not have to pay for connections or not be reliant on mobile connections which frequently fail. All smart 'phones today can read QR codes. Tesco (UK) provides free wifi in some of its British stores and Ahold is now testing the service in its Albert Heijn stores in Holland. In the latter case a test began last week. In six stores there will be a one hour time limit whilst in the others there will be no limit.Smart Move !
