商業活動以支付工具完成付款作業。時代變遷，支付工具亦隨之進化演進。科技進步，電子支付工具陸續興起，電子支付工具依照特性可有不同的分類，對於不同的使用對象，在不同的使用環境，依不同需求可選擇不同的工具。 金融卡是我國重要的支付工具之一，具有提款、轉帳、餘額查詢及繳稅費等功能，磁條金融卡因安全因素將全面轉換為晶片卡，晶片金融卡除具有磁條卡的交易功能，在安全性大幅提昇後，配合網路自動櫃員機在網際網路上已成為一項方便又安全的支付機制，未來可朝全方位金流工具發展。 本研究透過了解電子支付工具的分類及特性，並探討電子支付工具之國內外應用發展趨勢及相關失敗經驗，綜合研究資料及心得，分析晶片金融卡支付工具之優劣強弱，提出晶片金融卡支付工具未來發展建議，期能讓我國消費市場電子支付工具之發展更健全，以構建發展電子支付工具之完整版圖。 關鍵字：電子支付工具(Electronic Payment Tool)、晶片金融卡(Financial Chip Card)、網路自動櫃員機(eＡＴＭ)、金流(Cash Flow) / The payment of business activity is done by the payment tool. As time goes by, the payment tool is improving. Electronic payment tool is coming through the progress of technology. There are different categories in users, environments, and demands for various characteristics of the electronic payment tool.

With the original functions of the Magnetic Stripe Card plus security control, the Financial Chip Card can be also worked with eATM on the Internet and becomes a convenient and safe payment tool toward all-around cash flow development in the future. We study not only the categories and characteristics, but also all applications, trends, and related experiences of the electronic payment tool. We combine all the information and opinions about the Financial Chip Card as a payment tool to understand its strengths and weaknesses.
