During the transaction, the user ensures that the information is not illegally stolen by an unauthorized person or entity and that only legitimate users can see the user data.(3) Completeness of the data. To prevent the transfer of confidential information and data between the buyer and seller in the transmission process by malicious tampering, insertion and other forms of destruction.(4) Non-repudiation of information. It is mainly used to prevent the sender or

point of view, the PBOC1.0 specification defines the E-wallet/E-passbook application, which specifies the interface of the card and terminal, the technical specifications of the card itself, the application-related transaction process and the technical requirements of the terminal.To meet the needs of the development of financial IC applications, the People's Bank of China launched the PBOC1.0 revision in 2003 to complement the E-wallet/passbook application, adding a debit/Credit application co

That is, information ' 1 ' and information ' 0 ' is the difference between information ' 1 ' signal amplitude, that is, the signal is strong, information ' 0

develop all user applications that require high accuracy and speed, such as games. Through the company's software development kit (SDK), OEMs can easily integrate the contactless gesture technology that is easy for consumers into their devices in a cost-effective manner. With the popularization of voice control and Non-touch gesture control, they are rapidly becoming one of the next-generation human-machine interfaces for mobile devices and wearable

to carry out contactless bidirectional data transmission between the reader and the RF card in order to achieve the purpose of target identification and data exchange. The most basic RFID system consists of three parts:1. label (tag, i.e. RF card): consists of a coupling element and a chip, and the label contains a built-in antenna for communication between the RF antennas.2. Reader: The device that reads the label information (which can also be writ
