Tesco is preparing to introduce its RFID tracking by the end of the year, having been delayed by the setting of global standards for technology, according to a spokesperson.

“We will work with our suppliers in a working group that will be set up to take the issue forward,” he added.

The retailer is to use passive RFID tags in its warehouses to track high-value items, such as cameras, electric toothbrushes and razor blades, supplied to its 98 Extra superstores,

Tesco is one of several food retailers planning to implement RFID into the supply chain by next year.
