Some of the customer’s basic information are chosen as the input of the network; then the credit summary was got as the output of the network. There are two goals of the simulation of the credit card approval : one is using SVM from the bank’s point of view, to judge the approval of credit card by analyzing applicants’ information ; the other is using SONFIN from the accuracy of the judgment to applicants’ annually breach. The SVM provides an architecture to extract support vectors for generating fuzzy IF-Then rules from the training data set , and a method to describe the fuzzy system in terms of kernel functions. Thus , it has the inherent advantage that the model does not have to determine the number of rules in advance, and the overall fuzzy inference system can be represented as series expansion of fuzzy basis functions. Moreover ,the SONFIN contains five-layers of constructed network. The summary of the five-layer constructed network is as follows：1st layer：input layer；2nd layer：linguistic label layer, such as：large, small, etc；3rd layer：forms the formula of precondition layer of the fuzzy rule ；4th layer： consequent layer ；5th：layer : output layer. Finally, the simulation result can be the reference for financing institutes to evaluate customers’ financial status and taken into account the risk and given credit.
