The use of a mobile device with a merchant application may enable the merchant to turn the mobile device into a point-of-sale terminal that interfaces with a server. The server may receive from the mobile device a transaction via a network, in which the transaction includes transaction details for a purchase request made by a customer. In turn, the server may transmit a transaction token that identifies the transaction to the mobile device of the merchant. Subsequently, the server may receive the transaction token from a client device of the customer. The transaction token being transmitted from the mobile device to the client device using a short range communication that is independent of the network. After receiving the transaction token, the server may provide the transaction details of the transaction that matches the transaction token to the client device for display so that the customer may pay for the transaction.

Transaction processing using mobile devices

Disclosed are various embodiments for performing stateless verification of communication addresses. Encrypted verification data is generated for a user account, including a communication address and a first verification code, and a timestamp. The encrypted verification data is sent to a client, and the verification code is transmitted to the communication address. The encrypted verification data and a second verification code are received from the client. The communication address is verified in response to observing that the first verification code from the encrypted verification data matches the second verification code.

Verification of user communication addresses

Disclosed are various embodiments for performing stateless verification of communication addresses. Encrypted verification data is generated for a user, including a communication address, an identifier of the user, a verification code, and a timestamp. The encrypted verification data is sent to the user, and the verification code is transmitted to the communication address. The encrypted verification data and the verification code are received from the user. The communication address is verified based at least in part on the verification code received from the user and the encrypted verification data received from the user.
