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.
