Problems solved by technology

[0008] but the capabilities known so far come at a high human cost
and low level of automation
In addition, a violator may repair or replace a broken seal such that the optical identification of unauthorized tampering is virtually impossible for employees

Embodiment Construction

[0069] Figure 1a A first preferred embodiment of the invention is shown. The seal 1 comprises a connecting element 18 and a measuring element 13 . The connection member 18 is formed in a plate shape and has a thin thickness compared to the length and width. Connection element 18 includes chip 11 and antenna 12 .

[0070] In this case, the chip 11 and the antenna 12 are arranged within the connection element 18 and are surrounded by the material of the connection element. In another specific embodiment, the chip 11 and / or the antenna 12 can be arranged, for example, in the fastening element. The antenna generates electrical energy from the electromagnetic field and uses this electrical energy to power the chip 11 . The connection element 18 has a terminal opening 15 penetrating through the thickness of the connection element 18 .

[0071] The fastening element 17 protrudes from the lateral edge of the connecting element 18 . The fastening element 17 is in the form of an e...

Abstract

The invention relates to a method for sealing and testing a product having a seal (1) for manipulation, and to a corresponding seal (1). The seal (1) comprises an antenna (12), a chip (11), a measuring element (13) which is adapted such that the measuring element changes a specific physical property when the product is manipulated, and a measuring arrangement which is suitable for determining thephysical property of the measuring element (13). For sealing and testing the product for manipulation a step of arranging the seal (1) on the product to be sealed is carried out, such that the productis mechanically sealed. Furthermore, the seal (1) receives a test query by means of contactless data transfer from a write-read device, determines the physical property of the measuring element (13)as the first measured value by the seal (1), produces a reply to the query by the chip (11), transmits the reply to the write-read device by means of contactless data transfer, wherein the reply of the chip (11) relates to the first measured value and compares the first measured value with a reference value.

Description

technical field [0001] The invention relates to a method for checking whether a product has been tampered with. The present invention also relates to seals and systems for sealing the transport of items of value. Background technique [0002] To ensure the authenticity and integrity of the product, the product usually comes with a seal. With the help of seals (often also referred to as security seals), it is possible to determine whether a product has been tampered with. The integrity of the packaging of the product simultaneously indicates its integrity and is usually valid as evidence of its authenticity. Products can be containers in which items that need to be secured are arranged. [0003] The seal is not usually intended to prevent tampering of the product and / or the contents of the product; it is usually only used as a form of tamper evidence, e.g. Such as the housing of the calibration instrument) has not been (unauthorized) opened. If the seal has not been brea...
