Saw a new way to make a payment using Paytm at Bata today. Mother Dairy uses qr code that you have to scan. 98.4 sends you a sms with otp. Bata uses a different mechanism that is quite confusing to be honest. The guy entered my mobile number in his payment system. He told me that I would need to provide him with a code. I waited for sms like 98.4. Nothing. I checked the payment requested section. Nothing. The guy told me that I need to show him the code in the SHOW CODE section of the app. This section shows a number and a bar code that changes every minute. Cool. He entered the number at his end and payment was made. I had absolutely no control over how much money was going to be deducted. I don't think I missed anything. No sms before the payment was made. I only got a confirmation. Got a 10% cashback from Paytm so that's nice.
