Hello Nikita, thanks for reading.
1. banks spend at least Rs 3,000-Rs 5,000 on CAC. So while I wont venture a number at what level they become unit eco positive, they need above average spends on this. So think more mid-premium cards.
2. I'm not saying this is a loss-making portfolio, it just doesn't make as much money as the rest. I'm not sure if physical form factor is needed because QR acceptance is nearly ubiquitous. Unless physical card is for some metal show-off value.
3. We should remember that, NPCI will only allow small merchants to not pay MDR. Today most transactions are on large merchants, so they'll continue to pay MDR even on transactions less than Rs 2,000, as they do on any CC today.
4. It's 32%, we rounded it to 30% in the article, and said 'about' for better readability.
Hope this helps.
