What is digital currency OTP smart card? What is the use of digital currency?

From the moment the central bank officially released digital currency, the era of digital currency has really come. It has been successfully used in the Beijing Winter Olympics. The digital currency OTP smart card has brought great convenience to the Winter Olympics. What exactly is digital currency OTP smart card? What is the use of digital currency?

The digital currency OTP smart card is a brand-new electronic currency payment card. On the premise of retaining the security of the payment function, it adds more personalized options, securely and quickly accesses the mobile Internet, and provides mobile financial protection such as mobile phone transfers and online secure payments.

3. Application of digital currency OTP smart card

The digital currency OTP smart card has a built-in high-performance security chip, a low-power electronic paper screen, a Bluetooth module, etc., which the OTP module can be customized and configured. Our company will provide APK and SDK. Developers can control the display content and the functions to be implemented by developing applications, including payment, positioning, attendance, objects search, etc., which can be used in many fields, such as electronic wallets, all-in-one cards, membership points cards, password memory cards, and corporate employee cards. , electronic annual pass, smart password key, social security money card, game currency card, hospital card, campus card, parking card, internal shopping consumption card and other related requirements. All of the above can establish communication with the mobile phone through Bluetooth.

4. The role of digital currency

Digital currency can be considered as a virtual currency based on node network and digital encryption algorithm, which can track the flow of funds and help regulatory authorities to comprehensively monitor and evaluate financial risks. In addition, the central bank's digital currency technology is conducive to the transmission of interest rates of monetary policy. Digital currency technology supports "peer-to-peer" payment settlement, which improves the liquidity of market participants. Only the central bank digital currency that is generally accepted by the whole society can radiate this advantage to participants in different financial markets, thereby improving the liquidity of the financial market, which will make the term structure and transmission mechanism of interest rate smoother.

5. The core features of digital currency are mainly reflected in three aspects

① Since it comes from some open algorithms, there is no issuer of digital currency, render its distribution beyond the control of any person or institution;

② Since the amount of algorithm solutions is determined, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the excessive issuance of virtual currency;

③ Since the transaction process requires the approval of each node in the network, the transaction process of digital currency is sufficiently secure.

The advantages of Heyang Technology in the research and process of digital currency OTP smart card:

We use the self-developed cold pressing process, also known as low temperature lamination technology. The lamination temperature is controlled by the temperature control debugging equipment of the cold press, which can clearly grasp the changing temperature of the internal lithium polymer battery and send instructions to the terminal, while effectively controlling the lamination temperature and lamination time, so as to meet the temperature control packaging requirements for active smart cards. The cold pressing process (PCBA丨FPCBA) breaks the traditional hot pressing, making PCB, thin battery, iBeacon module, fingerprint module, blockchain, switch and other components embedded in the card and packaged, which can be widely used in communication, financial payment, object positioning and other fields.
