Smart cards have a wide range of applications and can be used in almost all stores.

For example:

Supermarkets: Lotus, Carrefour, Agriculture, Industry and Commerce, Century Lianhua, Family, Keke, etc.

Shopping malls: Shiyi Store, No.1 Food Store, Hualian Department Store, Yaohan and so on.

Chain restaurants: KFC, McDonald's, Starbucks, Pizza Hut, etc.

There are too many others, so I won't write them all.
