Different Types of UPI QR strings.

1. Static - A static QR string can be used to collect multiple payments on a single QR string.

   • These QRs are similar to what are being used by local shops and vendors to collect payments from a retail customer.

2. Dynamic - A dynamic QR string can be used to collect exactly one payment on a single QR string.

   • For each transaction, a customer has to create a new QR code, and each QR code will have a unique
     transaction Id associated with it, which can be used to reconcile transaction postback on successful
     payment.
