Abstract

In order to use mobile devices for business application, mobile applications and standard have grown fast – so called m-Commerce that normally uses WAP protocol to access remote web site wirelessly. WAP protocol has moved from WAP 1.0 to WAP 2.0 in order to lessen the developer’s load by simplifying and forcing language independency. WML has been used to provide web-like user interface to mobile device on WAP 1.0. And, cHTML has been used exclusively in NTT DoCoMo service. However, WAP 2.0 chooses XHTML-MP by considering existing WAP languages. The paper introduces and compares WML, cHTML and XHTML-MP in syntax and on experimental results. Besides, m-Commerce architecture on n-tier architecture is illustrated. The financial transaction system on online game is implemented in those languages as a mobile application to be compared.
