Gas stations need to bind the POS machine in advance before they can use the POS machine to process bank card purchases for customers.

The binding interface is shown in the figure below:

pos machine consumption interface

The main interface currently has only three interfaces, namely transaction record bank card consumption, self-made IC card consumption, and self-made IC card stored value.
