National Payments Corporation of India(NPCI) on Thursday said that customers can recharge NETC FASTags through BHIM UPI. Any BHIM UPI-enabled mobile app would now give vehicle owners the opportunity to recharge their FASTags on the go and avoid queues at toll plazas, NCPI said. The National Electronic Toll Collection(NETC) is a programme designed to meet the electronic tolling needs of the Indian market.
