A method for validating payment information for an online transaction is provided. A payment server can receive two representations of the same payment information. The payment information can be validated if it is determined that the two representations match. If there is no match, or the payment information is otherwise invalid, the payment information can be repaired based on a trusted representation of the payment information, such as stored payment information or an image of an associated value token. Payment information can be received via one or more communication channels, and can be provided by one or more consumer devices. A merchant service provider can validate payment information and handle transaction processing on behalf of a merchant.
