Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an electronic passport that can prevent being stolen, so that when the electronic passport is closed and placed in a pocket, purse or held in hand, it is impossible to use any reading device to read the non-contact smart card. The information in the chip can only be read by the reading device when the passport is opened, so as to prevent the use of illegally copied special reading devices to illegally obtain information on the electronic passport without the holder's knowledge

Embodiment Construction

[0012] Generally speaking, when there is no need to check passports, most ordinary people are used to putting their passports together in their pockets, purses, or in their hands. For the inspection by the inspectors, in addition to using special equipment for machine-readable inspection, the inspectors will also open the passport for visual inspection. The contactless smart card receives a carrier signal with sufficient energy through the antenna, converts it into energy and provides it to the contactless smart card chip for its working use. Metal materials have good shielding properties for the carrier signal sent by the non-contact smart card reader. Even if a thin layer of metal material covers both sides of the non-contact smart card chip antenna, the antenna cannot receive the signal. Carrier signal (there is no gap between the metal material and the antenna, completely covering both sides of the antenna), or the energy of the received carrier signal is not enough (there...

Abstract

The invention discloses an electronic passport capable of preventing furtive reading, wherein a non-contact intelligent card chip and an antenna of the non-contact intelligent card chip are packaged into one page in the passport; a layer of thin sheet metal is respectively embedded into the previous page and the next page of the page corresponding to the position of the antenna; and the dimension and the position of the sheet metals guarantee that the antenna can be completely shielded by the two sheet metals when the electronic passport is closed, so that carrier signals emitted by an antenna of a non-contact card reader can be shielded. The electronic passport can prevent utilization of special copying equipment to illegally acquire information in the electronic passport which is closed by a holder and placed in a pocket or a leather bag or held by hands, and prevent the electronic passport from being furtively read, and is favorable for protecting the safety of the information in the electronic passport of the holder.

Description

technical field [0001] The invention relates to an electronic passport, in particular to an electronic passport which can prevent being stolen. Background technique [0002] With the continuous development of smart card chip technology, the data encryption and protection mechanism of the contactless smart card chip is becoming more and more perfect, and the storage capacity is also increasing. It is being used in passports by more and more countries. A non-contact smart card chip with large capacity, data encryption and protection mechanism is implanted in it to realize an electronic passport that can carry more information. In addition to continuing to retain all the visual features of traditional paper passports, electronic passports can be passed through contactless The electronic card reader obtains more and more detailed information through machine reading in the non-contact smart card chip in the electronic passport, including digital photos, fingerprints, iris charact...
