User told me that she have the Java program cannot read Card Reader more than 2 times.
After then, the Java program will halt.

Even she had asked another user to use their own card, the result was no different.

I had tried uninstalled and installed Card reader with using anther usb port but in vain.

The Java version is JRE 1 .8 .0.91.

Please help !

That might be an issue with the hardware itself. Check its docs

Try getAtr().getBytes() before and after the call to the reader and see what that tells you if anything.

Have some good points.
However, the program use by many people but
only the user have the problem.
If any checking program can help us?
Java 8.91 and Java 7.101 are the current Java program.

Would have been nice if you'd included that piece of information in the original problem description. This TA is more focused on Java code problems, and this is more likely than not, as has already been said, some form of hardware problem, or some old hardware or OS of the machine in question, or underpitched RAM. You'd probably get a faster answer if you tell us all the detail you have, particularly regarding the spec of this machine.

Ask the manufacturer to eliminate the hardware as a cause of the problem

My guess is that the reader is tied to a specific version of Java (which it shouldn't be). Check the docs

More guesses include :

Disable TLS2
Uptry to USB 3 or downtry to 2.0.
Try a USB cable from another machine, and/ or another reader that works.
