PORTLAND, Ore. -- Retailers looking into radio frequency identification ought to consider testing it for themselves, if only on a small scale, said Carolyn Walton, vice president of information systems for Wal-Mart Stores, which itself is exploring the technology one step at a time.
"Don't enhance the field of dreams on RFID. Look long and hard at where to make an investment, and stick to the simple stuff. Start small, take baby steps, and pick off some of the low-hanging fruit," said
