Abstract: It is described an electronic circuit chip for an RFID tag. The electronic circuit chip comprises (a) an access circuit configured for coupling the electronic circuit chip to an antenna element of the RFID tag, and (b) a memory device being connected to the access circuit. The memory device is configured for storing a secret value, for making retrievable the secret value, and for deleting the secret value. Deleting the secret value is accomplished if the secret value has been retrieved by means of a first attempt procedure for retrieving the stored secret value. It is further described an RFID tag comprising such an electronic circuit chip and a method for managing the use of a read-only-once secret value by an RFID tag with such an electronic circuit chip.

Abstract: Aspects of the present disclosure relate to phase-change materials. In accordance with an example embodiment, a phase-change material has a crystalline structure that manifests changes that increase as a function of time. For example, such changes may be implemented for monitoring the time that a perishable item has been exposed to an environment having a temperature that is greater than a threshold temperature. Based on the changes, a characterization is provided, indicative of the exposure of the phase-change material to the environment having the temperature that is greater than the threshold temperature.
