Digital RMB “visual card” exposed, Shanghai tests “hard wallet” solution

Mobile Payment Network News: On January 5, the digital renminbi “hardware wallet” welcomed new progress. According to the People's Daily, in the staff canteen of Tongren Hospital affiliated to Shanghai Jiao Tong University School of Medicine, a doctor used the Postal Savings Bank's "visual card" to order food with the help of a digital renminbi "hardware wallet".

It is reported that the person participating in the pilot is Dr. Yu Yiming from the Department of Respiratory and Critical Care Medicine of Tongren Hospital, the discoverer of the first COVID-19 patient in Shanghai. He used the Postal Savings Bank's digital RMB "visual card" to complete the payment by swiping the card at the payment terminal in the employee restaurant. The entire process was similar to the operation of an ordinary bank card.

There is an electronic ink screen window in the upper right corner of the "Visual Card", which can display information such as consumption amount, balance, and offline availability.

According to Tongren Hospital, in the future, focusing on the development of the big health industry, Tongren Hospital will further pilot the use of digital renminbi in payment scenarios such as hospital diagnosis and treatment payment, physical examination and parking payment.

According to Mobile Payment Network, smart card wallets such as "visual cards" are a type of digital RMB hardware wallet. Consumers can understand them as our commonly used "transportation cards", and their money is stored in the cards. , you need to recharge the card in advance to make consumption, and this is also the key to "dual offline" payment.

So how to recharge smart card hardware wallets such as video cards?

Video cards can actually be divided into ordinary video cards and visual Bluetooth cards, which interact with smartphones through NFC and Bluetooth to complete operations such as recharging. Of course, for convenience, ATM machines and some self-service terminals may be modified and upgraded in the future to facilitate the recharge of digital RMB "hardware wallets."

The "Visual Card" interface in the digital RMB wallet of ICBC Mobile Banking App

Currently, the ICBC Mobile Banking App digital RMB wallet also has a "visual card" related operation interface. Including video card binding, payment collection, recharge, etc., which will only be displayed on Android NFC phones. It can be seen that ICBC uses the NFC function of the mobile phone to recharge and collect payments on the video card.

According to Mobile Payment Network, judging from the patents previously announced by the central bank, it summarizes hardware wallets as "digital currency chip cards", and digital currency chip cards can specifically include visual Bluetooth IC cards, There are 5 forms including IC card, mobile eSE card, mobile SD card, and mobile SIM card.

The visual Bluetooth card generally refers to a smart card with a screen that displays transaction amount, balance and other information. It interacts with the smartphone through Bluetooth, NFC and other methods, and can be used with the mobile app for query and account information synchronization. The above-mentioned products should be of this type, and we have also exposed similar products before.

Therefore, the digital RMB video card product mainly depends on how it interacts with other devices such as smartphones. Currently, in terms of price, NFC and electronic ink screen forms may be cheaper. The price will be higher if it has Bluetooth, fingerprint or even other functions, making it more suitable for wearable wallets.

Of course, according to Mobile Payment Network, the video card does not only have a "hard wallet" solution, but also supports a "soft wallet", that is, the digital renminbi is not stored locally in the card, but is only tied to the card. The digital wallet account is set, and the digital RMB is still stored on the server. The card interacts with the smartphone via Bluetooth and synchronizes account information within a fixed period of time. This form of visual card is actually the same as the digital RMB account in the App. The account information needs to be synchronized within a certain period of time. In addition to interacting with the smartphone via Bluetooth to synchronize data, the card can also interact with the acceptance card during consumption. The terminal uploads information for account synchronization and displays transaction information and balances.
