THD89 is a “full-scenario” chip that spans payment, security, identity, and IoT. It can be used in bank-level secure payment systems, meet government identity authentication and corporate security access control needs, and can be embedded in smart devices and brand card customisation projects. It has very high flexibility and adaptability.

Q1: What is the THD89 smart card chip used for?
A1: The THD89 is designed for secure payment cards, RFID credit cards, and other identification applications. Its support for both contact and contactless interfaces makes it versatile for use in banking, transportation, and access control systems.

Q2: Does the THD89 support dual interface applications?
A2: Yes. The THD89 is available in contact, contactless, and dual interface versions. This allows card issuers to deploy the same chip for different use cases while maintaining security and compatibility.

Q3: What security algorithms are supported by the THD89?
A3: The THD89 supports DES, 3DES, AES, RSA, and the Chinese cryptographic algorithms SM1, SM3, and SM4. This wide range of cryptography ensures compliance with global and regional security standards.

Q4: What communication protocols are compatible with the THD89?
A4: It supports ISO/IEC 7816 T=0, T=1, and ISO/IEC 14443 Type A (T=CL). This makes it compatible with most smart card readers and payment terminals in the market.

Q5: What type of memory does the THD89 use?
A5: The THD89 uses FLASH memory for data storage, providing high reliability and flexibility for updates during the card lifecycle.
