The first terminal 2 sends 304 a transaction amount TA to the server 4. The server 4 establishes 502 to 504 a verification code AC a length L of which is dependent on the amount of the transaction TA, and then sends 505 and 506 a request Req to the first terminal 2 and the verification code AC to the second terminal 5. The user returns 310 said request filled in with a copied code AC' to the server 4 using the first terminal 2. The server 4 compares 508 the verification code AC with the copied code AC' and sends 510, 512 a transaction validation or invalidation message to the first terminal 2 depending on the comparison.
