It's the first time to use medical insurance, but I can't use it after activation, saying I still need to save it. What is this?

In a nutshell, the way you usually withdraw cash from your bank account and put it in your pocket for consumption and payment is changed to directly deposit the money in your bank account on an IC chip, that is, you have an electronic wallet. In this way, you will avoid the risk of carrying cash change, losing or robbing counterfeit banknotes. Most of the funds are spent by individuals in a specific consumption environment. After the payee signs an agreement with the bank, he can transfer money to the consumer card through the bank card, and the consumer is spending with the consumer card.

Our company is a campus card system. Oh, let me give you an answer.

Generally speaking, there are two main ways to deal with the bank self-service deposit system, one is based on the forwarding processing of the bank front-end processor, and the other is based on the forwarding processing of the campus front-end processor.

The processing method is based on the forwarding of the bank front-end machine.

Generally speaking, the front-end machine of the bank first receives the deposit request sent by the deposit machine, subtracts the balance of the bank card according to the deposit amount, and then sends this information to the front-end machine of the campus, and the front-end machine of the campus completes the recharge of the campus card according to the deposit amount plus the balance of the campus card.

Here, taking a student as the subject of deposit operation as an example, the student inputs the bank card information, card password, campus card information and the amount to be deposited into the deposit machine, and the deposit machine encrypts and packages these main information and sends them to the front-end computer at the bank.

The front-end machine of the bank unpacks and decrypts the package through the security and communication processing module. If the card passes the verification, the bank processing module is called to subtract the amount of the corresponding card for transfer processing.

The bank business processing module transmits the processing result to the bank front-end machine, and the bank front-end machine calls the security and communication processing module to encrypt and package the content into a request package [see the interface description for details of data format], and sends the processing request to the campus front-end machine. The request package is the interface between the bank and the campus.

The campus front-end processor processes the request message sent by the bank front-end processor, unpacks and decrypts it through the security and communication processing module, and performs corresponding business processing according to the transaction code information in the request message (see interface description, such as deposit, inquiry, offset, etc.). ). At the same time, according to the campus card information and deposit amount information in the request package, call the one-card deposit processing module to add the deposit amount to the balance of the corresponding card to complete the transfer from the bank card to the campus card.

The campus front-end computer sends the response package of operation result to the bank front-end computer [see interface description]. The response package is the interface between the campus and the bank, which contains the return code of the processing result of the one-card system. If the return code number is successfully registered, the bank front-end machine sends the transaction success information to the registration machine; Otherwise, the bank front-end machine sends the transaction failure information to the registration center, and the bank makes registration correction.

The processing method is based on the forwarding of the campus front-end computer.

There are some differences between the processing mode based on campus front-end computer forwarding and the processing mode based on bank front-end computer forwarding. Generally speaking, the campus front-end machine first receives the deposit request sent by the deposit machine, and then forwards the information to the bank front-end machine, which subtracts the bank card balance according to the deposit amount. If it is successful, the campus front-end computer receives the successful return code and calls the program for processing. If it fails, the campus front-end processor receives the failure return code and notifies the storage machine.

Here, taking a student as the subject of deposit operation as an example, the student inputs the bank card information, card password, campus card information and the amount to be deposited into the deposit machine, and the deposit machine encrypts and packages these main information and sends them to the front-end computer at the campus end.

The campus front-end computer forwards these information to the bank front-end computer for request processing, and the request packet is the interface between the campus and the bank.

The bank-side front-end processor processes the request message sent by the campus-side front-end processor, unpacks and decrypts it through the security and communication processing module, and carries out corresponding business processing according to the transaction code information in the request message (see interface description, such as deposit, inquiry and offset), and calls the banking business processing module to subtract the deposit amount from the balance of the corresponding card according to the bank card information and deposit amount information in the request message for transfer processing.

The bank front-end computer returns the calculation result to the campus front-end computer. If the transfer is successful, the campus front-end computer calls the one-card deposit processing module to add the deposit amount to the corresponding campus card balance to complete the recharge transfer from the bank card to the campus card. If the transfer fails, the campus front-end machine sends the transaction failure information to the deposit machine, and the transaction ends.
