在一些涉及支付功能的app，一般需要绑定银行卡，除了靠用户手动输入银行卡号，用手机扫描银行卡也是一种常用的手段，查阅了写资料，发现ionic有CardIO插件可以实现这个功能，就兴致冲冲去尝试，结果有些失望。
下面介绍一下如何在ionic中使用CardIO实现扫描银行卡功能
相关CardIO插件的ngCordova说明

1、在入口文件main.js 中

const app = angular.module("app", ["ionic", "ngCordova", "ngAnimate", "ngCordova.plugins.cardIO"]);app.config(function ($ionicConfigProvider,  $cordovaNgCardIOProvider) {"use strict";$cordovaNgCardIOProvider.setScanerConfig( // 配置显示的参数{"expiry": false,"cvv": false,"zip": false,"suppressManual": false,"suppressConfirm": false,"hideLogo": true});$cordovaNgCardIOProvider.setCardIOResponseFields( // 配置返回的参数["card_type","redacted_card_number","card_number","expiry_month","expiry_year","short_expiry_year","cvv","zip"]);
});

2、在controller文件中使用

angular.module("app").controller("mineCtrl", ["$scope", "$cordovaNgCardIO",function ($scope $cordovaNgCardIO) {"use strict";$scope.scanBankcard = () => {$cordovaNgCardIO.scanCard().then(function (response) { // 扫描成功//Success response - it`s an object with card dataconsole.log("Success response");console.log(response);},function (response) { // 取消扫描//We will go there only when user cancel a scanning.//response always nullconsole.log("when cancel scanning");console.log(response);});};   }]);

3、在html中

<ion-view view-title="扫描银行卡"><ion-content><i ng-click="scanBankcard ()" class="icon ion-camera"></i></ion-content>
</ion-view>

尝试了以后效果不是很理想，CardIO插件只能扫描16位以下，并且是浮雕数字的银行卡，无法满足设计需求，只能暂时放弃。如有大家有什么解决办法，欢迎交流
