Aircash and its journey
QR code payment is a contactless payment method where payment is performed by scanning a QR code from a mobile app. This is an alternative to doing electronic funds transfer at point of sale using a payment terminal. This avoids a lot of the infrastructure traditionally associated with electronic payments such as payment cards, payment networks, payment terminal and merchant accounts.
There are different ways you can accept QR code payments as a business, but options are limited in some countries. In any case, you need to set up acceptance through the payment company offering the service for the particular mobile wallet/app processing the QR code.
