Two-dimensional Code originally appeared in auto parts manufacturing enterprises, at that time the full name of two-dimensional Code is "Quick Response Code" (QR Code), is a bar code system, the purpose is to improve the management system of the production line, can quickly and accurately enter a lot of information into the computer, and with so many years of scientific and technological development, Today's two-dimensional code is shining in various fields, especially the mobile payment this is because the two-dimensional code module has become the mainstream.

After Alipay launched scanning code payment in 2012, two-dimensional code payment quickly occupied the field of mobile payment, and has been widely promoted and used. At present, it has become the mainstream of online payment, whether it is shopping in supermarkets, eating in restaurants or taking public transportation, basically any consumption scenario has it.
In fact, in actual applications, mobile payment is only the main scan and swept these two types.
When we scan the code through Alipay, it is actually through the rules of the two-dimensional code module to parse out the content of the two-dimensional code and complete the transaction.
This process includes judging whether the QR code link is a payment link, judging whether the payment link is their own, and judging whether the QR code is valid after analysis. If it is a valid payment link and conforms to your own rules, you can proceed to the next step - initiate a payment request. Otherwise, information such as the QR code is invalid or unavailable will be displayed.
In addition to this type, there is also a type of passive scanning code payment, which requires the payment code to be opened and then scanned by the cashier with the scanning code gun. This type is also based on a payment link to complete the transaction, but in this link will contain some necessary information such as source, amount, merchant information and so on. Then this payment link can only be processed by its corresponding server, so that the interoperability between the multi-platform is realized.
The two-dimensional code module has greatly promoted the improvement of financial inclusion, can provide us with great convenience and efficiency, and has played an important role in promoting the development of financial technology, and with the continuous progress of technology and the continuous optimization of policies, it will continue to play an important role in the global financial field.
