RFID (Radio-Frequency Identification) technology is governed by various standards that define the rules and specifications for RFID systems. These standards ensure interoperability, compatibility, and reliability across different RFID devices and applications. Here are some of the key RFID standards:
ISO 14443: ISO/IEC 14443 defines standards for contactless smart card communication. It includes two parts:
- Part 1: Specifies physical characteristics and radio frequency (RF) power and signal interface.
- Part 2: Specifies the proximity card's initialization and anticollision protocol.
ISO 15693: ISO/IEC 15693 defines standards for vicinity cards (cards with a read range typically up to 1.5 meters). It specifies the communication protocol for high-frequency (13.56 MHz) RFID systems.
ISO 18000: ISO/IEC 18000 is a series of standards that define RFID air interface protocols for various frequencies and applications. Some key parts of this standard include:
- Part 1: Defines the general requirements for RFID air interfaces.
- Part 3: Specifies the parameters for the air interface in the 2.45 GHz frequency range (known as the "Active RFID" frequency).
- Part 6: Specifies the parameters for the air interface in the 860-960 MHz frequency range (known as the UHF RFID frequency).
EPCglobal: EPCglobal is an organization that develops standards for RFID in supply chain and logistics applications. EPCglobal's most well-known standard is the Electronic Product Code (EPC) standard. EPC is often used with the EPC Gen2 protocol, which is widely adopted for UHF RFID systems.
NFC (Near Field Communication): NFC is a set of standards for contactless communication at short distances (typically up to 4 cm). While NFC is often associated with mobile payments and smartphone interactions, it is based on RFID technology. Key standards include ISO/IEC 14443 and ISO/IEC 18092.
AIM (Automatic Identification and Mobility): AIM is an industry association that publishes various standards and guidelines related to automatic identification technologies, including RFID.
ASTM (American Society for Testing and Materials): ASTM has published standards related to RFID, including performance and testing standards.
IEEE (Institute of Electrical and Electronics Engineers): IEEE has published standards related to RFID, such as those specifying air interface protocols and application standards.
UHF Gen2: The UHF Gen2 standard is a widely used air interface protocol for UHF RFID systems, often referred to as "Gen2" or "EPC Gen2." It is recognized by EPCglobal and is commonly used in supply chain and logistics applications.
These are just a few of the many RFID standards and specifications that exist, covering a wide range of frequencies, applications, and use cases. The choice of which standard to follow depends on the specific requirements of the RFID application.
