With wireless ECR integration, merchants can use their billing system to generate bills and send payment requests to the Paytm POS machine over the air. The Paytm POS machine and merchant billing system will be connected via cloud-based services.
The integration happens through internet connectivity. The Merchant Billing system should be connected to the internet, and once details are entered, the details are sent to the Paytm POS machine for further completion of the transaction. The response is then sent to the Merchant Billing system with success or failure and the transaction is closed.
