本文介绍了php javascript java applet智能卡在服务器上签名pdf的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在创建一个php应用程序，我在服务器上生成了pdf文件，需要用智能卡（使用智能卡读卡器）进行数字签名，需要2到60人。
I am making a php app where I have generated pdf file on server which needs to be digitaly signed with smart card (using a smart card reader) by 2 to 60 people.
一个简单的按钮，上面写着
A simple button that says
然后，如果用户在读者应用程序中没有智能卡说：
Then if the user has no smart card in reader app to say:
一个新的弹出窗口：
所有结束时：
是否可以完成以及如何完成？
Can it be done and how?
