History and development of RFID

A technology with several origins

Radio frequency identification developed through advances in radio communication, transponders, semiconductor memory and automated data processing. Its history is best understood as a sequence of capabilities: detecting a responding object, assigning an identity, storing application data and exchanging that identity across business systems. A patent date or a commercial introduction represents one milestone within this wider development.

The distinction between detection and identification remains relevant. A device that indicates the presence of an object does not necessarily transmit a unique identifier. A modern RFID transaction may include an identifier, memory access and authentication, depending on the selected IC and system.

1970–1973: a documented memory transponder milestone

Mario Cardullo and William Parks filed the application for US Patent 3,713,148 on 21 May 1970. It was granted on 23 January 1973. The patent describes a transponder system with alterable memory and energy obtained from an interrogation signal. It provides a primary record of combining remotely accessible data with a radio powered device. Cardullo and Parks, US Patent 3,713,148: Transponder apparatus and system, 1973.

This principle matters because a passive credential can hold information without a user replaceable battery. Later product families implemented different memory technologies, protocols and mechanisms for controlling access. The patent is a historical milestone, not a basis for treating all subsequent RFID implementations as technically equivalent.

From individual readers to networked identification

Commercial value expanded as identification data became connected to operational software. In a 2007 lecture, MIT Auto-ID Laboratory director John Williams described the challenge of converting numerous RFID observations into useful business events and sharing them across organizations. The problem extended beyond radio performance to context, data protection and enterprise integration. John Williams, MIT Auto-ID Laboratory: RFID systems and business events, 2007 lecture.

The resulting architectural distinction is fundamental: a reader observes a tag, while a business application interprets the observation. An inventory movement requires context such as location, time and process state. Repeated radio reads alone do not establish that a shipment has been received or that an asset has changed ownership.

Standards and contemporary systems

Air interface standards and event data standards address different layers of the system. GS1 Gen2 specifies UHF tag and reader communication. EPCIS defines a framework for exchanging visibility events; release 2.0 includes sensor related information. NFC specifications support interoperable proximity interactions across devices and tags. GS1 EPC Gen2 Air Interface Protocol, release 3.0.1, February 2026; GS1 EPCIS Standard, release 2.0, June 2022; NFC Forum: NFC Technology, technical overview.

Modern procurement therefore begins with the required application and installed ecosystem. Historical continuity does not make an older credential interchangeable with a newer IC. Reader commands, application structure and security configuration must be qualified together.
