Retailers will soon be able to offer customers another way of topping up mobile phones. BT's mobile internet division Genie has teamed up with prepayment expert to develop self service top up terminals accepting payments for all four mobile networks. Unlike rival De La Rue's PAYzone system, Qdodge doesn't require a retailer to facilitate the transaction, take payment or stock vouchers. Shoppers type in their requirements into the Qdodge keypad which issues a receipt printed with a four digit pin. By punching the pin into the phone, airtime is updated. Retailers with a terminal will receive a rental payment. "We're in discussions with a number of retailers from CTNs to the multiples," said a spokesman. "Qdodge should be up and running by October." {{NEWS }}
