Abstract:
1. A method for transaction authorization with the use of a mobile phone, comprising the steps of: receiving by a communication server (CS) a voice call establishment request to establish a voice connection to a standard MSISDN telephone number which uniquely identifies a transaction; determining, by the communication server, whether the voice call establishment request is a request for transaction authorization to be executed with the use of a text channel; determining, by the communication server, whether the voice call establishment request is a request for transaction authorization to be continued via a voice channel; rejecting the voice call establishment request based on a determination that the voice call establishment request is a request for transaction authorization to be executed with the use of the text channel; accepting the voice call establishment request and establishing the voice connection based on a determination that the voice call establishment request is a request for transaction authorization to be continued via the voice channel; transmitting, from the communication server (CS) to an authorization system (AS), information about the request, containing at least a telephone number of a user (UR) and the telephone number identifying the transaction; transmitting, from the authorization system (AS) to the user (UR), a request to enter necessary transaction parameters; receiving the necessary transaction parameters from a handset of the user (UR); verifying the correctness and completeness of the transaction parameters received by the authorization system (AS); determining that a transaction amount has been accepted by a transaction party responsible for funding the transaction; sending a message containing an instruction to reserve sufficient funds in an account of the transaction party to settle the transaction; verifying the completeness of all the transaction parameters received by the authorization system (AS); and transmitting the transaction for settlement based on successful verification of the completeness of all of the transaction parameters.
