According to the guide, foreigners coming to China can choose a series of payment services such as mobile payment, bank cards, cash, accounts, and digital RMB.
Why choose Visual Cold Wallet card?
Currently, digital RMB payment methods include scanning QR codes, touching merchant POS terminals with mobile phones, reading cards or wearable device cold wallets through "Tap and Pay", and pulling digital RMB payment options from online merchant platforms. Among them, the digital RMB cold wallet with a E-ink screen is even more popular because it can check the balance/transaction amount at any time.
Our advantaes
Compared with the mature traditional hot laminating processing technology, cold laminating technology is a process independently developed by Union Smart in 2014.

It can be used to package various components, such as lithium batteries/ink screens/fingerprint modules/ Various PCB circuit boards such as buttons/buzzers/accelerometers are pressed at low temperature/low pressure in a normal temperature environment, which can effectively protect the components inside.

They can be packaged into standard card sizes or other customized shapes. Among them, the digital RMB cold wallet visual card uses cold laminating technology, which makes payment more convenient for foreigners coming to China.
