I think the future is to never fill-in your cards info anymore, and maybe not even have a card at all. Once you start using something with a QR Code, it's much much better: - WeChat Pay and co. (in China); - PhonePe and co (in India); You usually have 2 ways to pay with those systems (only systems I'm familiar with, others might be different): - Merchand shows a QR Code; you scan it and enter the right amount manually. Merchand gets a confirmation. - Merchand shows a QR Code; you scan it but the amount and details are all pre-filled and you just have to confirm. In both cases, it's scan + click ok. Now, if worldwide banks in the world were to have a way to send money to each other without fees and with a single standard, they could make it happen (one can hope).
