Abstract

The invention discloses a security method for dual-card combination used for a communication terminal, which comprises the following steps that: a first card is provided; a second card is combined with the first card so as to form the dual-card combination; the first card or the second card is initialized so as to ensure the first identification code of the first card or a second identification code of the second card come into effect; the initialized first identification code or the second identification code is checked, so the dual-code combination loses effectiveness when the first card orthe second card is replaced by other cards or the first identification code or second identification code is ineffective.

Description

technical field [0001] The present invention relates to a dual-card system, in particular to a security method for dual-card combination of a communication terminal (such as a mobile phone). Background technique [0002] In general, many types of telecommunication networks have been established to provide diverse services to network users. The most widely used and well-known service provided by telecommunication networks is of course mobile telephony services, such as cell phones. At the same time, in order to make the functions of the electronic device provide more services, various surface contact cards with special circuits have been widely used in the electronic device. For example, a Subscriber Identity Module (SIM) card can be placed in a mobile phone, allowing the SIM card holder to use the phone's functions. By swapping SIM cards, one phone can be used by multiple SIM card holders, just like a personal phone. Furthermore, some telecommunications networks provide o...
