Abstract

The invention relates to a subscriber identity module (SIM) card with a non-contact interface, which comprises an SIM card and an antenna device. The SIM card is provided with C1 to C8 contacts; the antenna device comprises a coil part, a connecting handle and a contact conversion module; the contact conversion module is connected with the coil part through the connecting handle and is attached to the SIM card; the contact conversion module is provided with S1 to S8 contacts which are connected with the eight contacts on the SIM card through a conductive adhesive, so that antenna contacts are electrically connected with the SIM card. The invention also aims to provide a method for connecting an antenna with the SIM card. The contact conversion module on the antenna device can be well connected with the SIM card and the stability of the antenna is improved. The SIM card and the method have the advantages that: the eight-contact conversion module is adopted, the eight contacts of the SIM card and the eight contacts of the contact conversion module can be completely overlapped, and the eight contacts are positioned on the same plane, so that the problem of poor contact due to virtual connection of the contacts caused by unevenness of the contacts is solved.

Description

technical field

[0001] The invention belongs to the field of smart card manufacturing, and relates to a dual-interface smart card and a method for connecting it to an antenna. Background technique

[0002] A SIM card with a contactless interface is a SIM card that integrates both contact and contactless communication interfaces. It combines the advantages of contact and non-contact IC cards. Contact IC cards are widely used in finance, telecommunications, public transportation, social insurance and other fields due to their large storage capacity, strong reliability and high security. All SIM cards use contact CPU cards; non-contact IC cards are obviously superior to contact cards because they do not need to be plugged in and out, are easy to operate, fast in transaction, strong in anti-environmental pollution and static electricity, and are therefore popular among people as soon as they appear. It shows a good application prospect, and it has been widely used in the field ...
