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 The first preferred embodiment of the present invention is shown. The seal 1 includes a connecting element 18 and a measuring element 13. The connecting element 18 is formed in a plate shape and has a thin thickness compared with the length and the width. The connection element 18 includes a chip 11 and an antenna 12.

[0070]Here, the chip 11 and the antenna 12 are arranged in the connection element 18 and are surrounded by the material of the connection element. In another embodiment, the chip 11 and / or the antenna 12 may be arranged in a fastening element, for example. The antenna generates electrical energy from the electromagnetic field and uses the electrical energy to power the chip 11. The connection element 18 has a terminal opening 15 that penetrates 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 an elongated strip. In addition, the fastening el...

Abstract

The invention relates to a method for sealing and checking a product provided with a seal (1) against tampering and a corresponding seal (1). The seal (1) comprises an antenna (12); a chip (11); a measuring element (13) adapted to cause the measuring element to change a specific physical characteristic when said product is tampered with; and a measuring device adapted to for determining the physical properties of the measuring element (13). In order to seal and check the product against tampering, a step of placing a seal (1) on the product to be sealed is performed, whereby the product is mechanically sealed. In addition, the seal (1) utilizes non-contact data transmission to receive a test query from the read-write device, the physical characteristic of the measuring element (13) is determined by the seal (1) as the first measured value, and the chip (11) generates a response to the query Reply, using non-contact data transmission to send a reply to the reading and writing device, 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 invention also relates to seals and systems for sealing transportation of valuables.Background technique[0002]To ensure the authenticity and integrity of the product, the product is usually equipped with a seal. With the help of seals (also commonly referred to as security seals), it can be determined whether the product has been tampered with. The package integrity of the product also shows its integrity, which is usually effective as evidence of its authenticity. The product may be a container in which items that need to be secured are arranged.[0003]The seal is usually not intended to prevent tampering of the product and / or the items in the product; it is usually only used as a proof of tampering, for example, the seal is used to prove that the container is used for sensitive content (such as a shipping box for valuables, an envelope, or a counter such as a counter Th...
