Description

  The present invention relates to a portable terminal and a portable terminal cover in which a non-contact IC capable of non-contact communication is accommodated in a casing.

In recent years, a portable terminal in which a noncontact IC is accommodated in a housing has been proposed (see, for example, Patent Document 1).
The non-contact type IC receives a radio wave generated by a non-contact type reader / writer with a built-in antenna, and starts by obtaining electric power from a magnetic field generated by electromagnetic induction or the like. The non-contact IC can communicate with the reader / writer within the magnetic field range. Such a mobile terminal allows a user who has gone out to read information on a non-contact IC by holding the housing over a reader / writer at a station ticket gate, various retail stores, etc. It constitutes a part of the system that pays a predetermined amount by debit.

By the way, for reasons of characteristics of a non-contact type IC that performs communication by a reader / writer, a portable terminal equipped with a non-contact type IC is not contacted by a malicious third party without obtaining the user's consent. There is a possibility of so-called skimming in which the information is illegally read or rewritten. In order to solve such a problem, for example, a portable case has been proposed in which a skimming protective layer for blocking magnetic and electromagnetic waves is formed in a storage portion (see, for example, Patent Document 1).
