Keysy RFID Duplicator

The Keysy RFID Duplicator can copy up to four key fobs or cards onto one Keysy remote. This is convenient if you have multiple cards that you’re constantly switching between; this remote can streamline everything for you.

You can only duplicate it on a Keysy branded fob or card, so check with your security or building administrator before purchasing this duplicator. There may be restrictions regarding what a duplicated fob or card can look like. It is for 125 kHz cards. 

MM Electronicles Handheld RFID ID Card Copier

It is simple and easy to understand and comes with five key tags you can copy onto. Unlike Keysy, you can only put one card or tag onto each duplicated tag.

This is a great, inexpensive option if you anticipate making many key tag copies or want a simple option. It is for 125 kHz cards. 


Use the ACR1252U USB NFC RFID Reader III to copy 13.56 MHz cards. It can read and write more encrypted RFID cards. In addition, it has two other modes: peer-to-peer mode and card emulation mode.

The RFID reader also supports post-deployment firmware upgrades, meaning you won’t need to modify the hardware.

MIFARE Classic Tool

If you have an Android phone, you’re in luck. You can copy your high-frequency 13.56 MHz MIFARE RFID card directly from your phone.

This app allows you to read and write RFID cards; just make sure your phone has NFC enabled first.

What Is an RFID Card Copier? 

An RFID card uses radio frequency waves in key fobs or cards to transfer data and grant entry to buildings or other areas using entry controls.

The key card includes an antenna and an integrated circuit (IC); these components communicate information confirming your identity and granting you entry to a door.

An RFID card duplicator takes the information on one card or key fob and writes it to a new card, fob, or tag. With the right equipment, copying an RFID card can be relatively straightforward.

It’s important to note that criminals sometimes use an RFID duplicator to make unauthorized copies of keys, which we don’t condone. If you want to make multiple copies of your key for your apartment building or office, request permission first and explain why you want an extra copy.

Building owners and administrators should know how many copies of keys are floating around. This is important from a security standpoint.

How Does It Work? 

RFID copiers work by copying the data on your card and writing it to a new card, key fob, or tag. In the simplest cases, they work by simply pressing one button to read the data on the original RFID card and then pressing another button to write the data on the new device.  

The process of duplicating a 125-z EM4100 card or fob is pretty easy. First, hold the original card up to the duplicator, then push the red button. When you do this, you’ll hear an audible beep.

Next, hold the empty card, fob, or tag up to the duplicator and press the write button. That’s it; after this step, the card should be ready to go, and the data on the new card will be identical to the data on the original card.  

It’s more difficult to copy a 13.56 MHz card, which is what most HID cards are. These cards have radio frequency waves and must send more bits per second.

They are also inherently more secure than lower-frequency cards. To recopy one of these cards, you’ll need additional equipment and a computer.

Where To Buy an RFID Card Duplicator

You can easily buy an RFID card copier from online retailers like Amazon or eBay. When searching for products, you might see them labeled RFID key fob duplicator, card duplicator, card cloner, or key card maker. You can also check out our list of the best key card copiers below. 

Before buying, be sure to look at the iteration of your key card. Fobs, cards, or tags that run at higher frequencies are usually more complicated to copy than those at lower frequencies.

You might need additional equipment beyond a straightforward copier for these security cards. It’s also important to look at your key card’s brand or manufacturer and ensure it’s compatible with the RFID card duplicator you’re looking to buy. 

Basic copiers for lower-frequency cards are inexpensive; some are as low as $10. Copiers with higher frequencies will cost more money because copying the card is more complicated. 

Buying Guide 

  • Compatibility: Ensure that the duplicator supports the frequency and protocol of the RFID tags you intend to copy. Compatibility ensures successful duplication without compatibility issues.
  • Functionality: Consider the features and capabilities of the RFID copier, such as the ability to read and write different types of RFID tags, clone multiple tags, and store tag data.
  • Ease of Use: Look for a user-friendly RFID duplicator with intuitive controls and clear instructions. A simple interface simplifies the copying process and reduces the risk of errors.
  • Security Features: Ensure the RFID copier includes security features to prevent unauthorized duplication of sensitive RFID tags. Features such as password protection and encryption enhance security in your office or building. 
  • Durability: Choose a durable RFID copier that withstands regular use and environmental conditions. Quality construction and robust materials ensure longevity and reliability.
  • Cost: Compare the cost of RFID copiers from different manufacturers and suppliers. Consider your budget and the value provided by the features and capabilities of each device.


What types of RFID tags can be copied with an RFID copier?

The types of RFID tags that can be copied with an RFID copier depend on the device’s capabilities. Some RFID copiers can copy various types of RFID tags, including LF, HF, and UHF. 

Is it legal to use an RFID copier to duplicate RFID tags?

The legality of using an RFID copier to duplicate RFID tags varies depending on the jurisdiction and the intended use of the copied tags. In some cases, duplicating certain types of RFID tags may be illegal, especially if they are used for access controls or payment systems without proper authorization.

The key card comprises an antenna and an integrated circuit (IC). These components work together to transmit information, for example, verify your identity, and allow entry to a door. The reader will run and check the credentials, which means you cannot secure entry or exit if you have false credentials.

Final Thoughts

RFID copier technology has offered a convenient and efficient solution for duplicating RFID cards for over a decade. It provides flexibility and convenience in managing access control systems.

If you have an RFID card, it’s good to know the process on how it works. By leveraging RFID copiers, businesses, organizations, and individuals can easily create copies of RFID credentials for various applications, including office access, asset tracking, and inventory management.
