The concept of a physical card is obsolete. That North Americans and western Europeans for a good part still use them is just stickiness of the infrastructure, and habits.

Developing countries have mostly leapfrogged to total contactless payments.

In South Aast Asia, you typically scan a QR code and approve a payment from your own phone. Far less fraud as a result. Nobody is able to touch your card, you don't have one.

Europe likely identified they better make the jump.

I can assure you that south east asians also still have cards, despite not making most of their payments with it. Not all ATMs support withdrawing with just a QR code from all banks, for one.

There are benefits to non-QR based payment systems, such as not wanting to pull out your phone, open an app, scan a QR and approve to make a payment that takes me 2 seconds with regular contactless payments.

Physical cards are also a nice fallback to have in cases of running out of battery, theft, etc.

I don't really understand why this is better than tap and pay with a card. Why would I want a single point of failure for both my communications and my ability to make payments?

Qr apps just sound cumbersome compared to contactless tap to pay.

Who returns your money to you if you purchased something on mail order with this, and it turned out to be fraud?
