The Origins of the RFID Symbol

The RFID symbol means the radio-frequency identification (RFID) technology used to identify and track objects. The RFID Lab first developed the symbol at Auburn University in the United States.

The RFID symbology was created to provide a visual representation of RFID technology and to help promote the use of RFID in various applications. The symbol was designed to be simple and easy to recognize, with a distinctive shape that would be easily recognizable even to those unfamiliar with RFID technology.

People chose interlocking arrows to represent how RFID technology uses radio waves to communicate with RFID tags.

People chose the circle to represent the global nature of RFID technology and its potential applications.

The International Organization for Standardization (ISO) officially adopted the RFID logo in 2014, and it is now recognized as the global standard for representing RFID technology. The Global RFID icon is widely used in various applications, including product labeling, packaging, and marketing materials.

The organization develops and publishes international standards in all technical and nontechnical fields other than electrical and electronic engineering, which are the responsibility of the International Electrotechnical Commission.[7] As of February 2023, the ISO has developed over 24,676 standards, covering everything from manufactured products and technology to food safety, agriculture, and healthcare.

Electronic Product Code (EPC)

The Electronic Product Code (EPC) symbol standard is a widely adopted protocol for RFID symbols, particularly in the supply chain and retail industries. It provides a unique identifier for each item, enabling real-time inventory management, visibility, and traceability throughout the supply chain. EPC symbols use a combination of letters and numbers to represent product data, such as manufacturer information, product details, and serial numbers. This standardized format ensures compatibility and interoperability across different RFID systems and enables seamless data exchange between trading partners.

The EPC symbol has also undergone several updates and revisions since its introduction, reflecting changes in technology and industry standards. The most recent version of the EPC symbol is the Global Trade Item Number (GTIN) EPC, which provides enhanced functionality and increased data capacity. → Check out how GTIN works

Do All Credit Cards have RFID Symbol?

Not all credit cards have an RFID symbol. While many credit cards today come with RFID chips embedded in them, some older cards and certain types of cards may not have this feature. Additionally, some credit card issuers may choose not to include the RFID feature on their cards.

To determine if a credit card has an RFID chip, you can check it for the RFID symbol or contact the issuer to inquire about its features. It’s important to note that having an RFID chip on a credit card does not necessarily mean it can be used for contactless payments. Some issuers require cardholders to activate this feature before they can use their credit card for contactless transactions. If you want to use your credit card for contactless payments, check with your issuer to see if it has this feature and how to activate it.

Some examples of RFID symbols include:

  • The RFID blocking symbol, a circle with a diagonal line through it, indicates that a product or device has RFID-blocking technology. This symbol may be printed on the product or packaging / displayed on a label or tag attached to the product.
  • The RFID reader symbol is a stylized representation of an RFID antenna. This symbol is often used to indicate that a device or system can read RFID tags or chips.
  • The RFID tag symbol is rectangular with a curved line on the top resembling a miniature antenna. This symbol often indicates that a product or item has an RFID tag attached, allowing it to be tracked or identified by an RFID reader.
