Print and output the code, the wireless terminal through the code processing unit payment terminal The code agent mounted on the wireless terminal is automatically driven by recognizing the code printed on the screen output unit and / or paper and extracting the purchase information and / or payment amount, and the extracted purchase information and / or payment as described above. The present invention relates to a payment system and method for performing short-range communication payment by outputting an amount to a wireless terminal screen output and performing a series of payment approval processes, and then extracting payment information from an IC chip mounted in the wireless terminal.

As a general short-term payment method, there is a method using a ray such as infrared ray, and referring to infrared financial messaging (IrFM) of Infrared Data Association (IrDA), which is a payment standard, the IRFM is a bidirectional transaction. Is based on.

According to IrFM of IrDA, an infrared payment transaction is a first transaction in which a payment terminal device generates at least one purchase information and / or payment amount and provides it to a Personal Trusted Device (PTD) through IrFM, and the PTD transmits the payment information. The second transaction is generated and provided to the payment terminal device through IrFM.

However, referring to the short-range communication settlement process practically used in Korea, the two-way infrared payment transaction is performed in the payment terminal device due to the transaction rate limit of the infrared communication and / or the complicated payment authentication structure of the infrared transaction presented in IrDA.
