How use USB Magnetic Stripe Reader in C#

USB Magnetic Stripe Reader

A magnetic stripe reader is a hardware device that reads the information encoded in the magnetic stripe located on the back of a plastic badge.

We can use it to read the information contained in the magnetic cards.

Below I post the C# code in order to capture the swipe:

1. Add the event:
   

   public Form1()
           {
               InitializeComponent();
               KeyPreview = true;
               KeyPress += Form1_KeyPress;
           }

2. Manage the event KeyPress in the form:
   

   private bool inputToLabel = true;
   void Form1_KeyPress(object sender, KeyPressEventArgs e)
           {
               if (inputToLabel)
               {
                   label1.Text = label1.Text + e.KeyChar;
                   e.Handled = true;
               }
               else
               {
                   e.Handled = false;
               }
               if (e.KeyChar == (char)Keys.Enter) // if is the last char I do something
               {
                   // I do something
               }
           }

Remember: before you swipe the card, put the focus on the form or textbox where you want put the information read.

Please let me know if you have problems.
