GORILLA SUPPLY Credit Card Cleaning Cards, Dual Side Card Reader Cleaner, POS Terminal Magnetic Head Pre-Saturated Swipe Alcohol-Free CR80 (50 Cards)

I work for a big retailer and these work wonders on our card readers. I will definitely purchase again

Seems to work well enough.

My work never cleans their credit card machines and I was tired of my card not working. These did the trick.

Fantastic but need to fold in half to clean infrared sensor in pin pads as they are super thin

I manage a hotel, and these are a great price for a great quantity. Anyone who deals in key cards knows how frustrating it is when the key maker is dirty and will not encode a key and someone is staring at you tapping their watch and rolling their eyes. A quantity like this will last quite a while even at a hotel. But they definitely are fantastic, and they feel good quality. Perfect for key makers, pin pads (both swipe and insert), as well as electronic door locks that accept key cards (especially on the outsides of buildings with dirt and dust in the air).

I use these to clean the credit card swipe readers on outdoor locker kiosks. They are always in the weather with moisture and dirt on top of that. They work great cleaning the inside of the readers. They are very easy to use. They are white with some texture so they really show the dirt.

Good for office use or Hotel keys machine

If your credit card terminal's chip reader is not working I highly suggest trying these. It is probably just some dust. They work great!! High;y recommended
