RFID & EAS: The Key Differences


For anyone overseeing inventory management or retail security, inventory tracking is absolutely crucial, given that organized retail crime costs businesses roughly $30 billion per year. For most businesses, this means putting one of the two most prominent tracking technologies, RFID or EAS, in place. But which system is best?

Retail stores have used traditional EAS systems for tracking and loss prevention purposes since the 1960s, and to great effect.

RFID systems, on the other hand, are a more recent addition to the inventory tracking landscape, but with their read and write capabilities, businesses can use them for far more than anti-theft purposes. Both systems use physical tags (and sometimes labels) to keep track of assets and alert organizations to their loss, but only RFID systems allow organizations to go above and beyond simple source tagging and loss prevention.

In this piece, we’ll go into detail about how, exactly, EAS and RFID tags work, and explain their differences (and similarities) in order to help you make the best decision for your organization’s needs.

RFID & EAS: How These Systems Work and Their Similarities

EAS Systems

Electronic article surveillance (EAS) tagging systems have long been among the most commonly-used anti-theft measures in retail spaces, and they’re what come to mind when most people think of classic loss prevention measures.

EAS security systems consist of antennae (often placed at the store entrance in retail spaces), the EAS labels or tags themselves and tools that can deactivate or detach the labels and tags.

Strong sensor EAS tagging systems were considered the gold standard in EAS security for decades until new technologies, including RFID, began to appear.




RFID Systems

A Radio Frequency Identification (RFID) system includes RFID labels or tags and an RFID reader. RFID security tags feature integrated circuits (ICs) that store information about the source and transmit a signal containing that information, which the reader then receives.

Although it’s considered a new-and-improved EAS solution, radio frequency identification technology in fact has been around for many years, but only in recent decades has it become a popular tracking tool across numerous industries.

Despite their differences in terms of hardware, any RFID or EAS system will share certain commonalities. Both detection systems:

  • Are used as an effective security solution to organized retail crime
  • Can utilize either reusable tags or single-use labels

Where the EAS and RFID systems differ, however, is what they can tell you about the items marked with an EAS or RFID tag.


RFID & EAS: The Key Differences

While EAS and RFID systems are both helpful for anti-theft purposes, the introduction of RFID accessory tags to replace EAS systems has revolutionized inventory management.

Beyond its use in retail stores, RFID technology is useful in a range of other industries, including manufacturing, healthcare, transportation and warehouses. RFID can, for example, track items or materials as they pass through production and beyond, including automobiles, pharmaceutical products and more.

That’s because RFID tags also have read and write abilities, which means that those utilizing RFID systems can go further than simple tagging and can actually record and read specific details about items, such as their make and model, color, size, batch number, etc.

That ability enables retail store owners, warehouse managers and others to not only identify that an asset has been lost, but also generate useful data about the movement of specific assets.

EAS loss prevention systems, meanwhile, are primarily good for just that: loss prevention.

Some see EAS as the “simpler” solution in that any thought that goes into EAS tagging systems is over as soon as the tag has been placed and the assets are out in the world, but that’s an approach that ultimately leaves business owners in the dark. They will know when their organization loses assets, but not much more than that.


RFID vs. EAS: Which Is Best?

The choice between EAS and RFID systems is a complex one, and one that you shouldn’t make without considering what it is you want to get out of inventory tracking—basic loss prevention, or loss prevention and the opportunity to automatically collect asset data, optimize operational efficiency and make well-informed business decisions.
