Dynamic QR code display is a feature that allows a QR code to be generated on a device and displayed on a screen for others to scan and make payments. The QR code is dynamic in the sense that it can be generated for a specific payment amount or item, and can also have an expiration time, after which it becomes invalid.

• Dynamic QR codes are commonly used for making payments using digital wallets or mobile payment apps like Paytm, BHIM UPI, Google Pay, and others. They are particularly useful for merchants, small businesses, and individuals who need to collect payments from their customers.
• To display a dynamic QR code, you need to have a device with a QR code generator or a payment app that supports dynamic QR codes. You can generate a QR code for a specific payment amount or item, and display it on a screen for others to scan and make the payment. The payment is usually completed by scanning the QR code using a mobile payment app and confirming the payment amount.
• Dynamic QR code display can be used in a variety of settings, such as at point-of-sale terminals, in e-commerce transactions, and for peer-to-peer payments. It is a convenient and secure way to accept payments, and can help reduce the need for cash transactions.
