Electronic key capable of operating under non-contact communication mode

Abstract

The invention relates to an electronic password key, in particular to an electronic key capable of operating under a non-contact communication mode, which comprises a CPU (central processing unit), an electronic chip and an antenna, the CPU is connected with the electronic chip, and the electronic chip is connected with the antenna. The antenna is fixed in a groove. By means of the non-contact intelligent card chip in the electronic key and the antenna connected with the non-contact intelligent card chip, the electronic key can operate not only under a contact communication mode but also under the non-contact communication mode, so the universality of the electronic key in use is enhanced.

Description

technical field [0001] The invention relates to an electronic password key, in particular to an electronic key which can work in a non-contact communication mode. Background technique [0002] The electronic key is the core component of the third generation computer anti-theft alarm. One electronic key can manage and check all user-installed alarms. The key adopts programmed design, LCD screen display, independent power supply, and easy operation. It is the only tool for customers to modify passwords, unlock, and detect the status and functions of the alarm. Electronic key consists of CA digital certificate (software) and electronic key (hardware). The use of electronic keys is a way to realize electronic signatures. Electronic keys are the carrier of digital certificates. Digital certificates identify the unique identity of users on the network, which is equivalent to the user's "network ID card". The functions of electronic keys: (1) Authenticity: ensure that the identi...

Problems solved by technology

[0003] In the process of using smart card chips, most of the existing smart card chips are contact smart cards, so the card reader must be in contact with the contacts of the card to exchange information with the card, such as the bus card commonly used by everyone. , and all kinds of parking cards, but if the card is severely worn, it may cause poor contact between the card and the reader, and data cannot be provided or data errors occur. Moreover, the communication rate of the contact smart card chip is low, and sometimes the card often appears Put it on the card reader, there is no response or slow response

Thus, this greatly limits the use and reduces the versatility of the product
