Description

Technical Field

[0001] The utility model relates to a certificate, in particular to a certificate with a magnetic shielding layer double-chip double-winding antenna structure. Background Art

[0002] Documents are the carrier and handle of immigration and entry-exit management. Attracting talents is an important immigration management task. Issuing identity documents to high-level foreign talents so that they can enjoy basic working and living conveniences in China is a basic measure to achieve the purpose of attracting talents. As a document that has both entry-exit and social application functions, the identity document of foreign personnel has received great attention from the society.

[0003] Because entry and exit documents need to be used across borders, their inspection cannot be achieved by using the system-issued data verification method. Instead, according to the ICAO DOC 9303 technical specification, asymmetric cryptographic technology is used to achieve offline inspection. However, in my country, the issuance and inspection of resident identity cards has an independent operating system that is different from that of entry and exit documents. Due to the incompatibility of the two technical systems of entry and exit documents and resident identity cards, the identity cards of foreign personnel used as identity documents face irreconcilable problems in the use of immigration management departments and the public.

[0004] There are two scenarios for checking identity documents of foreign personnel: one is to check when they are used for customs clearance at border inspection ports, including domestic and foreign customs clearance ports; the other is to check when they are used as identity documents in the society, including immigration management departments and other government service and social public service departments.

[0005] 1. In the border inspection port inspection scenario: Because the passports held by foreigners and the entry and exit documents held by Chinese citizens comply with the ICAO DOC 9303 mechanism, both my country's border inspection departments and foreign border inspection departments use this mechanism for document inspection.

[0006] 2. In social use scenarios: Most of the passports, ID cards, and green cards in Western countries are issued in accordance with the ICAO DOC 9303 mechanism, and the ICAO DOC 9303 mechanism is also used for inspection in their own countries, which is consistent with the inspection method of border inspection agencies. However, in my country, because my country has the advantage of number of people and first-mover advantage in the issuance and use of ID cards, various industries have formed a huge usage base and a self-contained system, which is incompatible with the ICAO DOC 9303 mechanism. Identity documents of foreign personnel are forced to be issued using the ID card password technology system.

[0007] The embarrassment of identity documents for foreign personnel as they meet both entry and exit needs and social use needs is that: when used as entry and exit documents, they have to be in line with international standards and adopt the ICAO DOC 9303 mechanism; when used in society, they are faced with a system of identity cards that is not in line with international standards. Considering that the number of people holding identity documents for foreign personnel is relatively small (only tens of thousands), and the scenarios in which they are used are very wide, it is difficult to reconcile the two application systems of border inspection agencies and various industries in society. Therefore, the compatibility of the two can be achieved from the perspective of the document itself. Utility Model Content
