In one embodiment, the method sending a revocation request to the banknote, in response to the revocation request, receiving a cryptogram signed by the banknote, wherein the first cryptogram includes an identification number of the banknote and a revocation confirmation, and forwarding the signed cryptogram to a blockchain server of a blockchain for entering the revocation confirmation of the banknote identified by the identification number in the blockchain.

Revocation of cryptographic keys by way of a blockchain-based banknote

A security feature is presented for a security or value document. The security feature comprises a zinc sulfide luminophore in the form of particles. The zinc sulfide luminophore has the general chemical formula ZnS:Cu, M, X; here, M represents one or more elements from a group comprising the chemical elements Co, In and Ni; X represents one or more elements from a group comprising the halides F, Cl, Br and I; and the following applies: 0<x<0.002 and 0::; y<0.00015 and 0::; z<0.00050. The particles each have cubic phase portions and hexagonal phase portions. When excited by an electrical field, the zinc sulfide luminophore emits a first radiation in the range of the light spectrum between 580 nm and 780 nm. When excited by heating the luminophore to a temperature between 100° C. and 150° C., the zinc sulfide luminophore emits a second radiation in the light spectrum.

Security feature and method for the detection thereof, and security or value document

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.

The present invention firstly relates to a security feature for a security or value document. The security feature comprises a zinc sulfide luminophore in the form of particles. The zinc sulfide luminophore has the general chemical formula ZnS: Cu, M, X; here, M represents one or more elements from a group comprising the chemical elements Co, In and Ni; X represents one or more elements from a group comprising the halides F, Cl, Br and I; and the following applies: 0<x<0.002 and 0≤y<0.00015 and 0≤z<0.00050. The particles each have cubic phase portions and hexagonal phase portions. When excited by an electrical field, the zinc sulfide luminophore emits a first radiation in the range of the light spectrum between 580 nm and 780 nm. When excited by heating the luminophore to a temperature between 100° C. and 150° C., the zinc sulfide luminophore emits a second radiation in the light spectrum. Furthermore, the invention relates to a security and value document, which may for example be a bank note or a passport, an identity card, a driving license or a postage stamp. The invention also relates to a method for detecting and/or verifying the security feature according to the invention.

The invention relates to a mobile proximity coupling device () for inductive coupling with an integrated circuit of a proximity object, the integrated circuit comprising a coupling interface for inductive coupling, the proximity coupling device () comprising a contactless interface () being configured to inductively transmit a first number of commands towards the integrated circuit, and, after transmitting a respective command, to wait for a reception of a dedicated answer to the respective command from the integrated circuit within a predetermined time interval; and a processor () being configured to determine a quality indicator upon the basis of a second number of received dedicated answers to the first number of commands, the quality indicator indicating a quality of an inductive coupling between the contactless interface and the coupling interface of the integrated circuit.

A card reader device is configured to carry out communication with a contactless readable card according to standard ISO/IEC 14443 type B. In order to provide that a modulation index, which self-adjusts in close range in a presence of a contactless readable card, corresponds to a desired specified modulation index, the magnetic field is received and evaluated via a reception antenna of the card reader device. The modulation index is controlled or regulated accordingly in case of deviations between a measured modulation index and a specified value for the modulation index in order to approximate the measured modulation index to the specified value.
