Abstract
A banknote includes a processor and a memory. An identification number of the banknote is stored in the memory of the security element and identifies an anonymous banknote account managed by a central bank issuing the banknote and individually assigned to the corresponding banknote. A banknote-specific cryptographic key is stored in a protected memory area of the memory. A payment method executed with the banknote receiving a payment request for a payment with the banknote, generating a payment-specific cryptogram for authorising the payment with the banknote, wherein the cryptogram is generated from the identification number of the banknote and a payment-specific code as input values using the banknote-specific cryptographic key, and sending a payment authorisation including the payment-specific cryptogram.
