Abstract
To authorize a transaction, a first device sends to a first server a transaction-authorization request accompanied with an Id-PAN relating to a user account, and including an identifier of a second device. The first server sends to a second server a user-authorization request accompanied with the Id-PAN and transaction data. The second server sends to the second device a request for user approval including the transaction data and the user account data. The second device requests whether the device user approves a requested transaction. The second device sends to the second server a request for authorizing the transaction and data relating to user approval. The second server verifies whether the requested transaction is approved by the user. The second server sends to a server a verification result including a transaction authorization or refusal.
