根據行政院主計處資料，2003年我國每百人行動電話用戶數為110.8 戶居全球之冠。近年無線通訊技術由2G、2.5G至3G傳輸速率大幅提昇但價格下降，消費者可在行動通訊中搭配多媒體影音，輕易處理圖像、音樂、視頻等多媒體訊息，透過手機上網的行動商務將是一個符合消費者需求的全新的服務產業。

成功的行動商務不是將現有網頁加以修改配合手機螢幕大小與操作方式，而必須了解行動商務要成功須朝向個人化發展，所以如何安全又方便進行身分識別，將會是關鍵成功因素。傳統GSM系統對於身分識別已有很好的解決方案，利用SIM卡與STK技術，但唯有行動通訊業者能夠進行身分識別，導致行動入口網站僅有電信業者經營，這也是台灣行動商務發展受限原因。

若能打破此僵局，更多企業投入行動入口服務，建立起特有之社群，將來透過手機上網戶數將會超越由PC上網戶數，行動商務所能提供的服務將會消費者所需要的，以往電子商務難以獲利的窘境會被打破。對此本文提出以行動憑證進行身分識別與交易，會是一種可能讓行動入口網站獨立經營，不再是電信業者寡佔的市場。

According to the Directorate-General of Budget, Accounting and Statistics, Executive Yuan, R.O.C material, in 2003 our country every hundred person of mobile phone user number is 110.8 households, occupies crown of the global.
