It’s possible that Delhi Metro rail riders won’t need to bring tokens with them to ride the metro rail; instead, they may use their smartphones in place of the token.
According to reports, the Delhi Metro Rail Corporation (DMRC) would test a new phone-based QR code ticketing mechanism. The commuters won’t have to wait in huge lines to receive their tokens to travel if the experiment and the implementation of the ticketing technology are effective. Instead, they are able to do so simply utilizing their smartphones.
How it will function Check out the Delhi Metro Rail App. Using modern QR code technology, you may create electronic tickets. There will be a variety of payment methods available for use. After the transaction is completed successfully, a QR code is created. At the automated fare collecting (AFC) gates, passengers must hold their phones in front of the QR code reader. The user will thus be permitted admission to the Metro station.
