Validation of merchant-associated devices during mobile transactions

A computer-implemented method, comprising:

• receiving, by a user device and from a second device associated with a merchant, a communication session request for processing of a transaction via an a wireless connection session between the user device and the second device, the communication session request comprising a merchant identifier of the merchant and use instructions usable by the user device during establishing of the wireless connection session;
• responsive to receiving the communication session request, communicating with a server to validate that the second device is associated with the merchant for the transaction indicated by the communication session request,
• receiving, by the user device and from the server, an encryption key associated with the merchant, the encryption key for use during said establishing of the wireless connection session;
• encrypting purchaser information based on the use instructions, the purchaser information associated with a user of the user device, said encrypting using the encryption key;
• responsive to validation of the second device and receipt of the encryption key, establishing the wireless connection session with the second device;
• and
• communicating the encrypted purchaser information to the second device via the wireless connection session.

A device, comprising:

• a non-transitory memory storing instructions;
• and
• a processor configured to execute the instructions to cause the device to:
• initiate a transaction between the device and a second device associated with a merchant, the transaction for purchase of an item or a service from the merchant;
• receive, from the second device and in response to initiation of the transaction, a communication session request for processing the transaction via an a wireless connection session between the device and the second device, the communication session request comprising a merchant identifier of the merchant and merchant data usable by the device during establishing of the wireless connection session;
• responsive to receiving the communication session request, validate with a third-party server that the second device is associated with the merchant for the transaction indicated by the communication session request;
• receive, from the third-party server, an encryption key associated with the merchant, the encryption key for use during said establishing of the wireless connection session;
• encrypt purchaser information, based at least in part on the merchant data, the purchaser information associated with a user of the device, said encrypting using the encryption key;
• responsive to validation of the second device and receipt of the encryption key, establish the wireless connection session with the second device, and
• communicate the encrypted purchaser information to the second device via the wireless connection session.

A non-transitory machine-readable medium having stored thereon machine-readable instructions, when executed by a processor, cause the processor to perform operations comprising:

• initiating a transaction, via a user device, between the user device and a second device associated with a merchant, the transaction for purchase of an item or a service from the merchant;
• receiving, by the user device from the second device and in response to initiation of the transaction, a communication session request for processing the transaction via an a wireless connection session between the user device and the second device, the communication session request comprising a merchant identifier of the merchant and merchant data usable by the user device during establishing of the wireless connection session;
• responsive to receiving the communication session request, validating with a third-party server that the second device is associated with the merchant for the transaction indicated by the communication session request;
• receive, by the user device and from the third-party server, an encryption key associated with the merchant, the encryption key for use during said establishing of the wireless connection session;
• encrypting purchaser information, by the user device and based at least in part on the merchant data, the purchaser information associated with a user of the user device, said encrypting using the encryption key;
• responsive to validation of the second device and receipt of the encryption key, establishing the wireless connection session between the user device and the second device;
• and
• communicating the encrypted purchaser information to the second device via the wireless connection session.
