The typical example of domestic mobile payment based on SMS (short message service) is Industrial and Commercial Bank of China. In 2004, Industrial and Commercial Bank of China officially launched mobile banking services based on SMS nationwide to provide value-added services for personal online banking users.
In the mobile payment operation model dominated by financial institutions, users must replace the original SIM card of the mobile phone with a STK (sim tool kit, user identification application tool) card. STK cards, like SIM cards, can be used on ordinary mobile phones, but STK cards have higher storage capacity and can run application software. The payment method based on STK cards is similar to the mobile payment process based on SMS. Bank of China, China Construction Bank, China Merchants Bank, etc. have all provided STK mobile banking, but in the subsequent development, most of them have been replaced by other types of mobile banking.
Short message service. Short messages are divided into two categories: one is point-to-point short messages (SMS), and the other is campus broadcast short messages (CBS). Short messages mentioned in the general sense mainly refer to point-to-point short messages.
Short message service is a service that sends or receives character (160 English or numeric characters, or 70 Chinese characters) messages on digital terminals and has storage and forwarding functions. Short messages are not sent directly from the sender to the recipient, but are always forwarded through the SMS center. If the recipient is not connected (the phone may be turned off or out of service range), the message will be sent when the recipient connects to the phone again.
Point-to-point short messages are both a basic telecommunications service and can be used as a data transmission carrier for information service services to provide people with value-added services such as information on demand services and remote data operation services. Since short messages need to be stored and forwarded in the short message center, their real-time performance is weak.
Short message service supports international roaming with low latency, so it is particularly suitable for applications such as multi-user paging, E-mail, voice mail notifications and messaging services, but the specific functions provided to users and the corresponding charges still depend to a large extent on the service level provided by the network operator. Now, there are already a large number of applications that can use computers to receive and send short messages.
