Abstract

The ISO Standard 10536 for Contactless Integrated Circuit Cards specifies several different types of inductive antennae. The present card incorporates two such antennae on a single card. Between one and four small "local" coils (1) are produced as a printed circuit in the middle of the card. The larger "remote" antenna (2) is a coil which runs around near the outer edge of the card. The coils operate in phase, but have minimal mutual inductive coupling.
