You may need to slow down the swiper by reprogramming it so that the computer can have more time to process the information it receives. Use the information below.



  • Before proceeding, make sure that you are logged on to the computer as a user with administrator rights.





Measure initial speed

Before you start, you should test how quickly your swiper is reading characters. Here's how:

  1. Open up Notepad on your computer.
  2. Click inside of the Notepad.
  3. Plug in your USB credit card swiper.
  4. Swipe a credit card.
  5. Note how quickly it swipes.
  6. When we are done, we will do this again and you should see a noticeable difference.


Download utility

  1. Download the utility from MagTek here. Scroll down to the Demo Program section, and click download.
  2. The utility will allow you to type in cryptic commands that allow you to change settings on the swiper.
  3. Make sure you have a swiper plugged into your USB port.
  4. Go to your desktop and open the MagTek icon to run the software.


Reprogram the swiper

Before you do this step, please measure the initial speed of the swiper, as directed above.

It will take a minute before the software recognizes the swiper and updates the displayed message from "Attach Device..." to "Swipe card...".

  1. In the orange region, enter the following: "01 02 08."
  2. Click Send Msg. This will reboot the swiper. Sometimes it takes a few moments for the command to process and show a result. You should eventually see its light turn red, but this is not required.
  3. Then, type "02" and click Send Msg.
  4. If after sending the reset command ("02"), the swiper does not reboot (indicated by changing light colors), you can unplug the swiper and plug it back in. 


Measure the new speed

Now, open up Notepad and swipe a card like you did above. You should see that the swiper goes just a little slower than it originally did. If you have additional questions, then please contact
