Description
一种电子交易卡，尤其是指一种利用整流稳压模块及开关单元分别与外接的无线读卡机及芯片读卡机连接，由无线读卡机及芯片读卡机直接供电的无电池电子交易卡。
现今常用的功能性卡片、例如芯片金融卡、悠游卡或是保健卡，皆能将多笔使用者资讯存储于卡片中，例如芯片金融卡存储个人及帐户数据，保健卡则存储个人的病历数据。由于此类的塑胶卡片能存储大量的个人数据，普及率越来越高，因此身上往往必须携带多种不同的功能卡片以应付不同状况(例如领钱时使用金融卡、看病时使用保健卡)，造成携带上的不便。同时，由于功能性卡片含有大量个人隐私的数据，在现今盗取个资的犯罪愈渐猖狂下，此类功能性卡片的防盗机制备受考验。
为兼顾方便携带及隐私权保护，一种电子交易卡于焉诞生。此种电子交易卡包含了一般塑胶卡片会有的感应线圈及IC芯片，其中IC芯片存储各种不同种类的使用者数据，可插入芯片读卡机以存取使用者数据，或是经由感应线圈感应后存取IC芯片的数据，藉此将多种卡片的功能整合于所述电子交易卡中，易于携带。除此之外，更包含有生物辨识单元及显示单元，使用者可通过生物辨识单元辨识使用者身份，防止个人数据被窃取。而显示单元能显示所述IC芯片中存储的数据，让使用者仅需启动电子交易卡即能查看IC芯片中的各项数据，无须通过芯片读卡机。
所述电子交易卡为了提供多项功能(数据整合、防数据窃取、显示)，必须采用至少一种电源供电。若所述电子交易卡插入芯片读卡机，可通过芯片读卡机对其供电。但若是使用感应式的读卡机操作，感应式读卡机无法对电子交易卡提供电力，在所述电子交易卡中必须设置电池以独立供电至上述各种器件，因此现有的电子交易卡中皆设置电池来对各种器件供电，使得电子交易卡在制作上必须增加安装电池的时间成本，以及采购电池等相关零件的费用。另外，在长期使用下电池可能会没电，使用者必须烦恼供电问题。更甚者，若电池老化或损坏，可能造成电力不稳而损害IC芯片中的数据，而更换电池的过程又会造成使用上的麻烦及困扰。
发明内容
为使电子交易卡能长期使用且提供简便的供电，本发明提供一种无电池电子交易卡，通过整流稳压模块接收无线读卡机的电力，使无线读卡机可直接对本发明的交易卡供电，避免因电子交易卡本身的电池问题造成无法使用。
为达成上述目的，本发明提供的无电池电子交易卡能与外接的一无线读卡机或一芯片读卡机连接供电，所述无电池电子交易卡包含：
一整流稳压模块，能与所述无线读卡机无线连接，以接收所述无线读卡机提供的一交流信号并将所述交流信号转换成一第一直流电压；
一开关单元，与所述整流稳压模块电性连接，以及接收所述芯片读卡机提供的一第二直流电压；
一芯片单元，与所述开关单元电性连接，用以存储多个使用者数据，以及接收所述芯片读卡机提供的所述第二直流电压；
一电源管理电路，与所述开关单元电性连接，且包含一第一转换单元，所述第一转换单元降压所述第一直流电压或所述第二直流电压至一第一工作电压；
一显示单元，与所述第一转换单元电性连接，所述显示单元由所述第一工作电压供电运作；

另外，本发明亦可利用有线的所述芯片读卡机供电，同样不须设置独立电池来供电，且使用者可自由选择较便利的方式存取所述交易卡中的数据。
本发明更可设置一第二转换单元及一无线通信单元，在使用时可用手机、平板等使用者设备通过所述无线通信单元与所述交易卡连线，进而在使用者设备上浏览、读取使用者数据，提高便利性。
就安全层面而言，本发明利用所述生物辨识单元确保数据不被盗取。当所述生物辨识单元辨识使用者身份失败时，所述开关单元停止供电至所述芯片单元、所述显示单元及所述生物辨识单元，有心人无法破解取得数据。且由于本发明是由外接设备供电运作，使用者于所述交易卡使用完毕后离开所述无线读卡机或所述芯片读卡机的使用范围，所述交易卡会因无电力供应而自动断电，避免所述交易卡因持续供电运作而使有心人从中监听复制或非法下载，保护数据安全。

步骤S221：若辨识成功，所述生物辨识单元60发送一成功信号至所述开关单元20，所述开关单元20根据所述成功信号启动所述芯片单元30，使用者可通过所述芯片读卡机90存取所述芯片单元30的所述多个使用者数据。
步骤S222：若辨识失败，所述生物辨识单元60发送一失败信号至所述开关单元20，所述开关单元20根据所述失败信号停止对所述芯片单元30、所述显示单元50及所述生物辨识单元60供电，达到数据保护的作用。
在本发明的另一较佳实施例中，可进一步包含一第二转换单元42及一无线通信单元70。所述第二转换单元42可设置于所述电源管理电路40中，并与所述开关单元20、所述无线通信单元70电性连接，其中所述第二转换单元42同样可降压所述第一直流电压或所述第二直流电压至一第二工作电压并提供至所述无线通信单元70，使所述无线通信单元70可正常运作。所述无线通信单元70用以与外接设备、例如手机、平板、笔电、桌机等使用者设备连线。所述无线通信单元70能为可接收2.4GHz的无线传输电路，或是蓝牙、Wi-Fi电路。
当所述生物辨识单元60成功辨识使用者身份时，所述开关单元20除了启动所述芯片单元30外，同时启动所述无线通信单元70与所述外接设备通信连线，藉此让使用者可通过上述外接设备存取所述交易卡1的所述多个使用者数据。当所述生物辨识单元60辨识使用者身份失败时，所述开关单元20除了停止供电至所述芯片单元30、所述显示单元50及所述生物辨识单元60外，更进一步停止供电至所述无线通信单元70，使所述外接设备无法通过所述无线通信单元70存取所述芯片单元30存储的所述多个使用者数据，保护数据安全。
本发明利用所述整流稳压模块10使所述交易卡1拥有无线及有线两种供电功能，能利用所述无线读卡机80对所述交易卡1无线供电，亦能利用所述芯片读卡机90对所述交易卡1有线供电，不需要在所述交易卡1中设置电池，减少制作上的工时及零件成本，同时亦可避免电池老化而必须更换电池的困扰。
