According to the reform plan of "clarifying the property right relationship, strengthening the restraint mechanism, enhancing the service function, with the appropriate support of the state and the responsibility of the provincial local government", rural credit cooperatives are set up in all provinces and cities to be responsible for the "management, guidance, coordination and service" of rural credit cooperatives in all provinces and cities.

After the reform, there are three main modes of rural credit cooperatives: 1 and rural credit cooperatives. 2. Rural commercial banks. 3. Rural cooperative banks.

The provincial rural credit cooperatives invested in the establishment of rural credit cooperatives' fund settlement centers, realized the deposit and withdrawal business among rural credit cooperatives, rural commercial banks and rural cooperative banks, opened bank cards, joined the modern payment system of the People's Bank of China, and realized the inter-bank deposit and withdrawal business.

Credit cooperatives and social existence. The reform of credit cooperatives is managed by the provincial government and plays a functional role for social development together with the government. The rural economy mainly depends on the support of credit cooperatives, which have long-term cooperative relations and occupy the right time, place and people. It is impossible for foreign banks to develop in rural areas. The software and hardware of rural credit cooperatives compete with the four major state-owned banks and major commercial banks, and the total deposit exceeds 3 trillion yuan, second only to ABC, ICBC and CCB.

Credit cooperatives have opened the universal deposit and withdrawal service, which is much more convenient than the previous single withdrawal method, and the personnel are constantly optimized.

Digital signature (also known as public key digital signature and electronic signature) is an ordinary physical signature, similar to the signature written on paper, but it is realized by using the technology in the field of public key encryption, which is used to identify digital information. A set of digital signatures usually defines two complementary operations, one for signing and the other for verification.

A digital signature is a digital string, which can only be generated by the sender of the information, and others cannot forge it. This number string is also an effective proof of the authenticity of the information sent by the information sender.

Digital signature is the application of asymmetric key encryption technology and digital digest technology.
