How to clean my POS Mag Strip Reader? (First Gen 2.0)

  1. Obtain a cloth free of lint and oil. 
  2. Wrap the cleaning cloth around a credit card/debit card. Wrap the cloth around the card so that it completely covers the front and rear surface of the card with a single layer of cloth. 
  3. Add a very small amount of isopropyl alcohol to the cloth.
  4. Swipe the card back and forth gently through the reader. 
  5. Simply slide the card back and forth through the mag reader slot several times as though you were processing a credit sale. Do not push more vigorously or too quickly, or you might damage the reader.


Attempt to run a sale transaction. See if the reader will now recognize the information on the back of your card.
