                  问题描述

                  有没有办法将读卡器连接到我的网络应用程序 (javascript),这样用户就不必手动输入信用卡信息?

                  Is there a way to connect a card reader to my web application (javascript) so that the user don't have to manually type in the credit card information?

                  此网络应用程序用于在商店购买产品.用户点击要购买的商品,然后在阅读器中刷信用卡,他会得到一张收据.

                  This web app is for buying products on a store. The user clicks on what items he want to purchase and then he swipes the credit card in the reader and he will get a receipt.

                  推荐答案

                  其实是有可能的,因为简单的 USB 读卡器作为键盘输入设备.由于它充当键盘输入,一旦输入框成为焦点,您就可以刷卡,使用一些漂亮的 jQuery 等将其推送到隐藏字段,然后从那里处理它.

                  Actually, it is possible due to the fact that simple USB card readers act as keyboard input devices. Since it acts as a keyboard input, once an inputbox is in focus you could swipe the card, push it to a hidden field using some nifty jQuery etc and then process it from there.
