Unlike the U.S., credit cards never became a mainstream form of payment in China, but the Asian country is already leading by example by leapfrogging many other countries in cashless tech.

The folks over at Mamahuhu, which features cross-cultural comedy, food, travel and culture content with a twist -- demonstrate how easy it is to go cashless in modern China, by using their phones only.

From homeless people to restaurants, almost every business or person has a unique QR code or a machine-readable matrix code that links up with their bank account without the need of personal information. Most notably, more than $5 trilion was processed in mobile transactions in 2016 alone.

Check out how Matt and Alessio of Mamahuhu fare in their cashless adventure in the eight-minute video above.
