With the growing use of RFID technology, standards are developed to make sure that RFID will be compatible with industries and manufacturers. They control protocols and make communication between tags and readers go hands free. This article explains key RFID standards and their impact on the world.

What RFID Standards Are?

RFID standards are the globally recognized guidelines of how RFID systems work. They guarantee that the RFID devices and software are compatible, secure and efficient. Without them, companies and industries would be working with mismatched technology that would make it harder to track and manage assets effectively.

Why RFID Standards Important?

RFID standards will ensure that products are interoperable across the vendor and the user. They are set of guidelines that enable companies to create complementary products like various types of tags, readers, software and accessories.

Standards also facilitate the expansion of markets and the competition among the industry, which leads to the lowering of the prices of standardized RFID products. They also contribute to building widespread confidence in RFID technology, and help businesses to adopt and integrate RFID technology into their operations.

Industry specific, national, regional and global organizations develop and issue standards. And two leading the way are the International Organization for Standardization (ISO) and GS1. Together these groups approve standards and protocols for universal specifications of RFID equipment. They create global standards for technologies to be adopted worldwide.

What are the current RFID standards?

The continuous development of RFID technology is accompanied by standard creation to fulfill the requirements of emerging industries. Several current appropriate standards exist within the RFID domain.

1. ISO Standards

The International Organization for Standardization through its standards enables RFID components to work together via standardized protocols for tag data structure, wireless communication and security functionalities and testing specifications. The following three standards represent common examples among those developed by ISO:

• Contactless smart card ISO 14443
• For vicinity cards, ISO 15693
• For air interface communication, ISO 18000
• ISO 19794 for biometric identification

The standards and guidelines set by this organization help create a safe RFID technology foundation that enables inter-industry interoperability at global levels.

2. EPC Standards

EPC system assigns exclusive Electronic Product Codes to RFID tags which creates possible identification through EPCglobal Network tracking systems. The Auto-ID Center began developing the EPC system that GS1 now administers through its position as the global non-profit organization focused on supply chain standard management. EPC standards include:

• Generation 2 EPC for UHF tags
• EPCIS for information sharing
• EPC Discovery for tracking tags

Standards established through EPC have enabled businesses to optimize their logistics operations which allows them better inventory management while supplying enhanced supply chain visibility.

3. NFC Standards

NFC works as an interface that permits devices like smartphones along with smart tags to communicate through wireless connections within limited range distances. NFC technology depends on ISO standards ISO 14443 and ISO 18092 while using further specifications that include:

• The encoding of data takes place through the NFC Data Exchange Format (NDEF).
• NFC Forum Type Tags for compatibility between different NFC-enabled devices
• Companies utilize NFC Forum Tag Certification as an independent assessment program for sustaining product quality and meeting industry standards.

Contactless payments together with access control systems and interactive advertising are the main areas where NFC technology finds its applications.

4. RAIN Standards

RAIN RFID is a passive UHF RFID system which operates between the frequency range of 860-960 MHz. RAIN RFID Alliance works as a worldwide organization that supports standards for UHF RFID adoption. RAIN RFID standards integrate ISO 18000-6C and EPC Gen2 with additional features that include RCI (RAIN Communication Interface) and TMM (RAIN Tag Memory Mapping) and API (RAIN Application Programming Interface).

• The RAIN Communication Interface (RCI) allows readers to be configured through this exportable and importable format.
• RAIN Tag Memory Mapping (TMM) provides an organization system for tag memory contents.
• Through RAIN Application Programming Interface (API) organizations gain the ability to implement software integration that functions effortlessly.

The RAIN RFID technology operates in three primary sectors: retail establishments along with logistics networks and asset identification operations. Through automation it helps businesses run their inventory management tasks better and operate more efficiently.

Organizations That Standardize RFID

A variety of organizations take on the responsibility to set and maintain RFID standards. Here are the big players:

4. ANSI (American National Standards Institute)

ANSI maintains control of RFID standards operating in the United States to fulfill both international regulations and domestic requirements.

Classification of RFID Standards

The RFID standards are divided into categories of industry, geographic scope, and national regulations. Here’s how they break down:

1. Industry-Specific RFID Guidelines

RFID regulations are developed to regulate a particular industry like veterinary services, security and tracking. There are different sectors that have unique needs for RFID use, so that such use is in compliance and efficient in their respective fields.

2. International RFID Standards

International bodies have set these standards to regulate the RFID operations worldwide. The two leading global regulatory agencies are ISO and GS1. They develop universal specifications in order to set up RFID technologies to work without fail across borders.

3. Local RFID Guidelines

RFID operations in a specific region are governed by these standards. In order to reduce interference and increase efficiency, it offers the operating guidelines for frequency bands like 5725–5850 MHz, 2400.0–2483.5 MHz, and 900–928 MHz.

4. RFID National Guidelines

Each country has its own regulation in overseeing local RFID operations.

RFID Standards by Country

Standards in Japan

The Ministry of Internal Affairs and Communications (MIC) is responsible for establishing RFID standards in Japan. The nation has allotted the 952–954 MHz UHF spectrum for RFID usage. High-powered passive tag systems can function with an antenna power of 10 mW to 1 W and an antenna gain of 6 dBi, yielding an EIRP of up to 4 W. Low-powered systems up to 10 mW do not require a license, however users of high-powered systems do.

Standards in China

Not to mention that China is working hard to align its RFID standards with international standards. The Standardization Administration of China (SAC) is in charge of this procedure, while the RFID National Standards Working Group is in charge of hardware-related matters including frequency allocation and tag-to-reader communication. It is the responsibility of the Article Numbering Center of China (ANCC) to ensure that products with Chinese labels are coded in accordance with the Electronic Product Code (EPC) system.
