The Dos and Don'ts of Cleaning Card Readers with Cleaning Cards


Card readers have become an integral part of our daily lives. From credit card machines at retail stores to access control systems in offices, card readers are responsible for reading and processing various types of cards. However, over time, these card readers can accumulate dirt, dust, and debris, leading to performance issues and even complete malfunctions. That's where cleaning cards come in. In this article, we will explore the dos and don'ts of cleaning card readers with cleaning cards, providing you with essential tips to ensure the longevity and efficiency of your card reader.

1. Understanding the Importance of Cleaning Card Readers

Card readers, just like any other electronic device, require regular maintenance to function optimally. Without proper cleaning, these devices can suffer from reduced performance, inaccurate readings, and ultimately, a shorter lifespan. Cleaning card readers with cleaning cards helps remove built-up dirt, dust, oils, and even magnetic particles that might hinder the card reader's proper functioning. Regular cleaning not only enhances performance but also prevents costly repairs or replacements.

2. Dos of Cleaning Card Readers:

2.1 Use Appropriate Cleaning Cards

When it comes to cleaning card readers, using the right cleaning cards is crucial. Not all cleaning cards are created equal, and using an incompatible or subpar cleaning card can potentially damage your card reader. Check the manufacturer's recommendations or consult the user manual to identify the correct type of cleaning card that suits your device. It is worth investing in high-quality cleaning cards specifically designed for card readers to ensure maximum effectiveness and safety.

2.2 Follow Proper Insertion Instructions

Each card reader might have slightly different instructions for inserting the cleaning card correctly. Familiarize yourself with the user manual or any instructional guides that accompany your card reader. Typically, the cleaning card needs to be inserted in the same manner as a regular card, following the designated slot and orientation. Make sure to insert the cleaning card slowly and with caution to avoid any potential damage to the internal mechanisms.

2.3 Avoid Excessive Force

While cleaning card readers, it is essential to remember that excessive force is not necessary. Cleaning cards are designed to perform their job efficiently without the need for excessive pressure. Applying too much force while inserting or running the cleaning card can result in bent or damaged components within the card reader. Gently insert the cleaning card and allow it to glide through the reader, employing a light touch.

2.4 Clean Regularly

Regular cleaning is key to maintaining the optimal functionality of your card reader. Depending on the usage frequency and environment, it is advisable to clean the card reader at least once every two weeks. However, high-traffic areas or locations particularly prone to dust accumulation may require more frequent cleaning. Establish a cleaning schedule and stick to it to prevent any issues arising from neglected maintenance.

2.5 Keep the Surrounding Area Clean

It is essential to not only clean the card reader itself but also the surroundings. Dust and debris can accumulate near the card reader, especially in areas with high foot traffic or near entryways. Regularly wipe down the area surrounding the reader and ensure it is free from any loose dirt or particles that could transfer onto the cards or the cleaning card itself. Remove any potential sources of contamination, such as food or liquids, from the vicinity of the card reader.

3. Don'ts of Cleaning Card Readers:

3.1 Don't Use Abrasive Materials

When cleaning card readers, avoid using abrasive materials, such as paper towels, cloth with rough textures, or cotton swabs with hard tips. These materials can scratch or damage the sensitive components of the card reader, leading to functionality issues. Stick to using only soft, lint-free cleaning materials, such as microfiber cloths or the recommended cleaning card provided by the manufacturer.

3.2 Don't Use Excessive Moisture or Cleaning Solutions

While it is essential to keep the card reader clean, excessive moisture or the use of cleaning solutions can be detrimental. Card readers are sensitive electronic devices that can be damaged by liquid exposure. Therefore, avoid spraying any cleaning solution directly onto the card reader or the cleaning card. Instead, only slightly dampen the cleaning card with a small amount of recommended cleaning solution, if necessary, and ensure no excess moisture remains.

3.3 Don't Clean During Peak Operating Hours

Cleaning card readers should be done during periods of low activity or when the card reader is not in use. Avoid cleaning the card reader during peak operating hours to prevent any disruptions or inconveniences to customers or employees. Plan your cleaning routine accordingly, ensuring minimal impact on the regular operation of the card reader.

3.4 Don't Neglect the Chip Reading Area

While cleaning the card reader, pay special attention to the chip reading area. Chips can accumulate dirt and oils, hindering proper reading and causing errors. Utilize approved cleaning cards specifically designed to clean the chip reading area, ensuring the removal of any debris. Take care not to touch the chip directly or apply excessive pressure while cleaning.

3.5 Don't Neglect Maintenance Beyond Cleaning

Cleaning cards aid in removing external dirt and particles, but other aspects of card reader maintenance are equally important. Regularly inspect the card reader for any signs of wear and tear, loose connections, or malfunctions. If you notice any issues, immediately contact the manufacturer or a trusted technician for assistance. Regular firmware updates, when available, should also be applied to ensure the card reader is up to date with the latest security features and performance enhancements.


Cleaning card readers with cleaning cards is a vital practice that ensures longevity, reliability, and accurate performance of these essential devices. By following the dos and don'ts discussed in this article, you can maintain your card reader's optimal functionality and prevent avoidable issues. Regular cleaning, using approved cleaning cards, and adhering to manufacturer instructions will help extend the lifespan of your card reader, saving you time and money in the long run. Remember, a well-maintained card reader guarantees smoother transactions and a more secure environment for all users.
