Auto loans into a single system, there is an electronic signature function. Electronic signature function sub app and micro-channel remote signature.
When the micro-channel remote signed, will share a small two-dimensional code program.
Customers get two-dimensional code, scan code into their own documents for authentication, (Tencent nuclear body) electronic signature -

Call the applet to generate two-dimensional code functionality, the applet server provides three ways to generate.
This is an alternative getUnlimited interface, which does not limit the number of calls to meet business needs.
