The rise of the third-party payment even has a significant influence on human beings. However, although the service of the third-party payment has been popular abroad, the existing laws and regulations in Taiwan have not been complete. Consumers are under the situation where the functions and risks of the third-party payment are unpredictable.

The payment method most frequently used by consumers during online shopping; 2. Consumers’ usage intention of the third-party payment service; 3.
