La chaîne J.C. Penney's (similaire à Wal Mart) développe un système de paiement pour ses clients sans argent: paiements par gadgets mobiles ou par puce d'identification RFID!

His plan is to eliminate cashiers, cash registers and checkout counters, replacing them with a patchwork of technology solutions, such as WiFi networks, mobile checkout, RFID (radio frequency identification) technology tracking systems for merchandise, as well as self-checkout options.
