The code in the label is read (110) by a reading terminal in an automated manner. A transaction message including the public key from the seller, a public key of a purchaser, and a signature of the transaction message with a private key of the purchaser, is generated (114). The message is transmitted (118) toward a distant server, which records the transaction through a communication network.</p> |
