Authentication System FAQ

Acquition, breakage and loss of a IC card

If I put my IC card in my wallet with an IC commutation pass such as ICOCA, will this have any effect on the card or pass?

A1. If you put several noncontact IC cards in your wallet together, they can be electromagnetically coupled. As a result, an IC card reader may not read their data. This problem occurs particularly with cards of the same type, such as ICOCA, PiTaPa、nanako、and WAON. Since it is possible your card will not be readable, put it in a separate wallet from your other cards.

A2. There is a commercial soft-magnetic film which you can put between IC
cards.This film might prevent their electromagnetically coupling even in the
same wallet. Please buy this type of film on your own.

For example, the following product can be used for this purpose: http://flux.bz/pass-case.html
