How do I make a dynamic QR code?

Dynamic QR codes can be generated automatically for each transaction using UPI-enabled POS systems. They include specific transaction details like the amount and a reference ID. Apps like Paytm for Business offer this functionality, enabling faster and automated billing for merchants. For general use, a dynamic QR code generator allows you to create a code with an editable destination URL, which can be changed at any time without reprinting the code.
