Appendix A, Appendix B and Appendix C of this standard are informative appendices. This standard is proposed by the State Administration of Standardization and is drafted by the National Anti-counterfeiting Standardization Technical Committee (SAC/TC218). The main drafters of this standard are: Huan Huiyong, Liu Jinliang, Mei Qiong, etc. This standard is first formulated.
GE/T20205-—2006
GB/T202062006
0, 11995 (The People's Republic of China Bills Law) Chapter 1 Article 1 and Article 7 clearly stipulate that in order to standardize bills and safeguard the legitimate rights and interests of the parties in bill activities, maintain economic order, and promote the development of social main market economy, this law is formulated, and "the signature and seal on the bill are signatures, stamps or signatures plus signatures." Therefore, in domestic economic and circulation cities, stamps and signatures are convenient bill settlement funds. The only legal payment order of the customer, influenced by the traditional Chinese culture, domestic bill settlement is mainly in the form of stamps.
0.2 With the development of China's economy, the business volume of banks has increased, and the amount of bills processed is getting bigger and bigger. In terms of judging the authenticity of the bills to be tested, the traditional method of checking the seal is that the bank counter folds the corner of the bill to be tested, and manually locates the corresponding position of the reserved seal on the corner line, and then completes the comparison by visual inspection. This method leads to problems such as inconsistent verification standards, low verification accuracy, and difficulty in ensuring verification quality. Once used, it will bring great economic and trust problems to banks and customers. In terms of the proper use and storage of customer seal cards, there is a lack of safe, convenient and standardized management methods. At the same time, the verification speed is slow, the reserved seal cards are difficult to transmit, and the authenticity of bills in different places is very difficult to distinguish. The difficulty in obtaining documents and the inability to conduct deposits and withdrawals for public business have seriously restricted the development of bank business. With the rapid development of science and technology, the computer automatic comparison technology of the whole stack verification has been produced, which has greatly improved the safety of the seal model and effectively prevented the occurrence of criminal cases. It has greatly improved the work efficiency and optimized the electronic management method of the reserved seal card! The network off-site verification of the special seal of the bill has been realized, making it possible to conduct deposits and withdrawals for public business. The release of this standard will help to use scientific and effective management methods, standardize the market of verification technology, set the design standards, production specifications and system performance indicators of enterprises, improve and ensure the quality of verification technology, meet user needs, and facilitate insurance companies to determine the insurance premium rate of the seal verification system product liability insurance, and provide a strong technical guarantee for the effective implementation of the (Law of the People's Republic of China on Bills of Exchange).
