This does look interesting, but TBH, I don't think its the end of credit cards per-se. One main reason:

What if my phone's battery is dead ? Does that mean I can't buy anything ? What happens in an emergency ? Credit cards are easy as they're quite low tech physically (a magnetic strip, a chip and some plastic).

Other things would be stuff like: not everyone has a phone, but would still like a credit card, etc. There are countries where phone penetration (and not even smart phone) is not very high, but the population still need to have credit cards.

Granted, I can see it being used as an alternative, but doubt it will be the "end of credit cards"

Go to an ATM.

There are also countries where SMS payments are much more popular than credit cards. It's not a one-payment-system world.

Exactly, and you end up using a "card" anyway

Okay then smart guy, go to a bank teller.

Using a card on the extremely rare occasion that you forget to charge your phone is a world of difference from using it 10 times every day.
