The most common type of digital wallet is an app on your phone that stores the data from your physical credit and debit cards, 驾照, 票和更多. 你可以通过从卡上输入数据来添加数据, 与账户同步, 或者在应用程序内给信用卡或车票拍照, 所以你的手机会为你读取信息.
购买或兑换门票, 输入你手机的密码, 或者使用ID, 然后你可以将手机对着销售点设备进行支付, 或者向代理出示您的电子机票以便扫描.
A digital wallet may also refer to the system online where you have inputted your payment details once and, 从那时起, you don't need to enter it again because the retailer or e-pay provider has stored it for you. To make purchases, you need only enter your email and password for that provider, for example 贝宝.
