Sticker for e.g. access control, has coupling unit connected with radio frequency identification -chip over connection line, where sticker has tensile strength, which is low so that sticker is teared or rippled during substrate separation

摘要

The sticker has a foil arranged on a side of an adhesive layer. A radio frequency identification (RFID)-chip is arranged at or in the foil. A coupling unit is connected with the RFID-chip over a connection line. The sticker has a tensile strength, which is low so that the sticker is teared or rippled during separation of a substrate. The foil exhibits a set of layers and is water soluble, where the foil is dissolvable after a predetermined time interval. The foil is made of cellulose and/or polymer material. Independent claims are also included for the following: (1) a method for admission control during admission of person in delimited areas (2) a method for consumption charging for a visitor within delimited area (3) a method for product identification.
