Background|

With the high speed development of Chinese economy, industries have higher and higher requirements for ID identification certificates, mainly including management of certificate information content, certificate security, anti-counterfeiting, digitization and informatization etc.
ID identification certificates are used in more and more fields including personal information management, traffic information management, small-amount consumption, roll management (campus/army), book lending, reward & punishment records etc.
Features of Solution|
Application of contactless IC card technology in certificates promotes electronic certificates. contactless IC card technology features large storage, high security, without exposed point and stain preventive, non-magnetic, anti-static and anti-radiation etc., as well as unmatched advantages comparing with bar code, magnetic stripe card and touched IC card technology:
- High Reliability: with data stored for more than 10 years; write/wipe over 100,000 times. Features non-magnetic, anti-static and anti-radiation.
- Convenient Operation: adopt radio frequency identification technology and needn't insert card. The read/write machine can read/write into the card chip in an effective scope, reducing operation time.
- High Security: data encryption and deencryption through chip specific security module and CPU.
Overview of System|
The electronic certificate solution provided by Tongfang Microelectronics Company applies non-touched IC card technology in certificate anti-counterfeiting and multi-application. This solution is based on Tongfang THR2408 contactless CPU card chip, including hardware and software.

This system fits for lots of fields such as enterprises, government bodies, armies and campus etc.
System Architecture|
This system mainly includes 2 functional modules of certificate issuance and multi-application:
- Functional module 1: issuance of certificate
The certificate issuance module hardware: issuance server, contactless IC card read/write machine and certificate printer with read/write machine embedded; software: certificate issuance software and read/write machine driver programs.
The issuance module is to complete initialization of the electronic certificate, including 2 functions: print the personal ID information into the certificate; through read/write machine, write into the chip the personal ID information, anti-counterfeiting information and relevant multi-application information.

- Functional module 2: multi-application of certificate
THR2408 chip features 8K-byte EEPROM memory as well as high security and flexibility, and can be used for multi-application.

System Security|
Security of this system lies in:
- Integrated circuit features complex manufacturing process and devices worth more than 100 million dollars. It will be costly to counterfeit.
- DES/TDES encryption/deencryption coprocessor and 32-bit truly random number generator offer a comprehensive data encryption and security controlling mechanism;
- Highly secure management over internal data and communication of the chip through chip OS (COS);
- Each chip has a unique 8-byte ID number (UID).
