The End of Cards

In Thailand, I use a debit or credit card barely once a month.
I use cash, or I do a transfer with one of the many online, phone based payment apps, many of which give you a virtual Mastercard debit card anyway.

So how close are we to replacing the traditional cash transfer with Crypto?

Closer than you think. If you can do a super fast traditional bank transfer using Fiat, and almost all shops and businesses accept transfers here.Then the same phone and QR code can transfer Crypto. Not a huge leap is it?
Adoption is the key......and stop using bank cards. Let's make them redundant.
