• Near field communication: operating frequency of 13.56MHz, communication distance is usually within 10 centimeters.
• Dual mode: Supports both active mode (generating RF field) and passive mode (load modulation response) simultaneously.
• Three working modes: card reader mode, card simulation mode, and point-to-point data transmission mode.
• Compatible with mainstream standards: Supports protocols such as ISO/IEC 14443 A/B, ISO/IEC 15693, FeliCa, etc.
• Flexible interface: Common communication interfaces include I2C, SPI, UART, which facilitate connection with MCU or embedded systems.
• Low power design: The card detection has extremely low power consumption (standby microampere level) and supports battery powered devices.
• Built in hardware encryption: supports data encryption and CRC verification to ensure the security of near-field transactions and pairing.
• Ready to use: Typical applications include mobile payments, electronic access control, bus cards, and Bluetooth fast pairing.
