We present an adhesive sticker which allows contactless Smartcard function widely independent of the object material which it is sticked to. Recently interest raised for such a sticker to be attached on any mobile phone for contactless payment applications. This is seen as precessor of near field communication (NFC) technology helping to introduce contactless payment with mobile phone. In this context we consider antenna design with field simulation software and evaluate electrical antenna parameters of samples fabricated in the Smartcard process flow. Aspects for conformance to the ISO/IEC14443-2 and NFC card standard are considered and an optimized composite design is proposed.
