Hello, Wal-Marts of the East! You've got company.

Korea's second largest supermarket chain is counting on RFID to understand its customers' purchasing behavior.

Samsung Tesco last year equipped its shopping trolleys and baskets with RFID chips to track customer movements at each of its 69 stores. The supermarket chain is a joint venture established in 1999 between consumer electronics giant Samsung and U.K. supermarket operator Tesco, according to an article posted today by ZDNet Asia.

With RFID, we can make it more convenient for shoppers by placing products [on the shelves and aisles] according to their profiles and habits," said a Tesco rep.
