What are the types and application ranges of CPU cards

CPU card (Card with a Central Processing Unit) is a smart card with powerful computing and data processing capabilities. It integrates a dedicated central processing unit (CPU) and can be used to Store and process complex data, as well as perform secure processing. Identity authentication and transaction processing. We will start a discussion around CPU cards to reveal the important role of CPU cards in the digital age.

The CPU card is a smart card with powerful computing capabilities. Compared with traditional smart cards, the CPU card integrates a central processing unit (CPU), which has higher computing speed and stronger data processing capabilities. Through the computing power of the CPU chip, the CPU card can perform complex data operations, encryption operations and algorithm operations to achieve more advanced functions and stronger security.

The principle of the CPU card is based on the design idea of the computer system. It contains core components such as central processing unit (CPU), memory (RAM, ROM) and input/output devices. The CPU is responsible for controlling the operation and running of the card, the memory is used to store data and programs, and the input/output devices are used for data interaction with the external environment. By running pre-installed applications and operating systems, the CPU card can implement a variety of functions, such as identity authentication, encrypted communication, electronic wallet, etc.

There are three main types of CPU cards. Contact CPU card, non-contact CPU card, dual interface CPU card (Dual Interface Card). The dual-interface card combines contact and contactless technologies and has two interfaces, which can communicate with the card reader through physical contact or contactless interaction through near field communication.

The contact CPU card uses metal contacts to make physical contact with the card reading device, and transmits data through the contact interface. This contact method is stable and reliable, with high transmission rate and safety. Contact CPU cards are usually used in scenarios that require higher security, greater data processing capabilities and faster data transmission speeds, such as the financial field.

The contactless CPU card uses wireless radio frequency technology (such as RFID or NFC) to communicate with the card reading device in the near field without direct contact with the card reading device. This contactless method is convenient and fast, and users only need to hold the card close to the card reader to interact. Shenzhen Aisen IoT's contactless CPU cards are usually used in scenarios that require fast interaction and frequent card swiping, such as public transportation, Access Control, etc.

Dual interface cards combine the advantages of contact and contactless technologies. It has both contact and contactless interfaces, which can transmit data to the card reader through physical contact or interact wirelessly through near field communication. This enables the dual-interface card to have greater application flexibility and compatibility, and can adapt to different types of card reading devices and interaction modes. Users can choose contact or non-contact methods to interact according to actual needs, achieving more convenient and wider use. As a combination of contact and contactless technologies, dual-interface cards combine the advantages of both interfaces. It can not only meet the security requirements and data processing capabilities of traditional contact CPU cards, but also have the convenience and fast interaction characteristics of non-contact CPU cards. Dual-interface cards have a wide range of applications, providing more options for finance, transportation, identity authentication and other fields.

The structure of the CPU card mainly includes chips, antennas, contact interfaces and plastic card bodies. The chip is the core component of the CPU card, including central processing unit, memory, encryption module and other components. The antenna is used to communicate wirelessly with the card reader, enabling contactless interaction. The contact interface is the metal contact of the CPU card, which is used for contact interaction with the card reader. The plastic card body protects the chip and other components and provides the card's external structure and shape.

CPU cards are widely used in many fields. In the financial field, CPU cards are widely used as financial smart cards to support secure payment, storage and management of personal financial information. In the field of electronic identity authentication, CPU cards are used as chip modules in identity documents to implement functions such as electronic identity authentication, digital signatures, and data encryption to improve the security and convenience of identity authentication. In addition, CPU cards are also used in electronic ticketing, Intelligent transportation, logistics tracking and other fields, providing safe and convenient solutions for various scenarios in the digital era.
