Macy’s and JCPenney join Walmart in leading the charge as retail RFID apparel tagging explodes. Over the past several weeks Macy’s and JCPenney have provided a clear view of just how close RFID is to becoming ubiquitous in apparel retailing. Last week JC Penney revealed it is pushing RFID-tagged jeans, shoes and bras to all 1,100 stores. Last month Macy’s said it will begin to roll out item level tagging at all stores by Q3 of next year. Predictions are that the Apparel RFID Market is set to hit 20 billion tags in 2021.
