Abstract: A subscription identifier is communicated between the billing server and subscription server. The billing server receives a subscription identifier text message from the user device. The billing server identifies a carrier server from the subscription identifier text message. The billing server receives an authorization text message from the user device in response to an authorization request text message and charges an account of the carrier server that has been identified. If the charge has been successful, then the billing server transmits a renewal notification text message to the subscription server. The subscription server updates an account having the subscription identifier to reflect a new expiration.

Abstract: A parking request text message is transmitted from a user mobile phone to a billing server and is forwarded to a parking server. The parking server makes a charge API call to the billing server, including a custom text, an amount to be billed and a msisdn of the mobile phone. The billing server charges an account at a carrier server corresponding to the msisdn, receives a charge confirmation from the carrier server, transmits a billing result to the parking server, and sends a confirmation text message to the user mobile phone with the custom text. The parking server updates a parking data structure to indicate that parking has been allotted based on a parking identification in the parking request text message.

Abstract: A code is communicated between the billing server and subscription server. The billing server receives a code request text message from the user device. The billing server identifies a carrier server from the code request text message. The billing server receives an authorization text message from the user device in response to an authorization request text message and charges an account of the carrier server that has been identified. If the charge has been successful, then the billing server transmits a code redemption text message to the user device including the code and a link to a redemption page of a website of a subscription server. The subscription server processes redemption to a code and transmits an account set up page to the user device.

Abstract: A repeat payment computer system includes a merchant server and mobile billing operator server that are programmed for user acquisition through carrier billing and subsequent conversion to credit card billing. An advantage of the process is that the user does not have to enter credit card information for the default billing cycles to occur. The user only enters a phone number and password. Fewer barriers are provided for the user to become a regular repeat customer of the merchant server. The fees associated with mobile billing according to the default billing cycles have to be paid by the merchant server and may be too high in the long run. The merchant server can avoid the high fees associated with carrier billing by switching the user to billing according to the credit card information provided. The user is typically switched after the user has already become a regular customer.

Abstract: A method and system of processing a sale of an article, a virtual article, a service or a functionality such as a game is described. A code is generated by a server. A charge request is transmitted to an account server to charge an account of a user for a value of the code. The code is transmitted to a user device. The code is then processed by redeeming the code, wherein redemption of the code includes receiving the code from a user device and in response allowing access to the user device to the article, virtual article, a service or a functionality.
