Abstract
A method for sealing and checking a product for manipulation with a seal and to a corresponding seal, wherein the seal comprises an antenna, a chip, a measuring element, and a measurement device. For sealing and checking the product for manipulation, a step of arranging the seal at the product to be sealed is carried out, wherein the product is mechanically sealed. The seal receives a check query by means of contactless data transmission from a read-write device, determines the physical property of the measuring element as a first measurement value by the seal, prepares a response to the query by the chip, sends by means of contactless transmission the response to the read-write device, the response of the chip relating to the first measurement value, and compares the first measurement value with a reference value.
