A contact chip card is a type of smart card that requires physical contact with a reader to function. It contains an embedded microchip that stores and processes data, making it ideal for secure transactions, authentication, and identification.

Key Technical Specifications:

• Communication Standard: ISO/IEC 7816.
• Chip Types:
  • Memory Cards: Store data but lack processing capabilities.
  • Microprocessor Cards: Feature a built-in processor for encryption and authentication.
• Security Features:
  • PIN protection for secure access.
  • Cryptographic algorithms for data encryption.
• Data Storage: EEPROM memory, typically ranging from 256 bytes to several KB.
• Operating Voltage: 3V or 5V, depending on the chip model.
• Applications: Used in banking (EMV cards), government IDs, SIM cards, and access control systems.
