Intelligent signature seal with electronic label and two-dimensional bar code

Abstract

The invention discloses an intelligent signature seal with an electronic label and a two-dimensional bar code, which is characterized in that a disposable self-locking type signature seal (1) is internally embedded with an electronic label chip (2), an electronic label inner ring antenna (3), an electronic label outer ring antenna (4) and a two-dimensional bar code (5) with a injection molding method in one step; the electronic label in the signature has the structure with the inner ring antenna and the outer ring antenna; the outer ring antenna supports the identification range of 5m, so that the identification, the mobile reading and writing, the location and the long-term tracing management of a plurality of signatures can be realized at the same time. When the signature seal is cut off normally, only the outer ring antenna is damaged; the inner ring antenna can still support the identification distance of about 10cm and is kept for the secondary verification and the file archive. The invention provides a signature seal product having functions of the storage, identification, verification and anti-counterfeit of the electronic data. Particularly, the invention is suitable for various containers, container trucks, electricity meters, postal parcels, bank cash boxes and tail boxes, and the other sealed containers or packages required to supervise and trace the information.

Description

technical field [0001] The present invention is based on the fields of radio frequency identification and sealing, and is suitable for all kinds of containers, container trucks, electric meters and electric meter boxes, postal parcels, bank cash boxes and tail boxes, and other airtight containers or packages that need to be supervised. The seal provides regulatory security with the non-reproducibility of electronic tags; at the same time, it provides safe and accurate information services for production, sales, warehousing, logistics and other links. Background technique [0002] Electronic tag RFID (Radio Frequency Identification) is a non-contact automatic identification technology, which is essentially a means of item identification. By determining an electronic code for the identified object, the electronic code is written into the electronic This electronic tag is fixed on the object to be identified. When it is necessary to identify the object, use the reader-writer c...
