IEC 63652-2:2026 pdf download,NFC Forum Specifications – Part 2: NFC Data Exchange Format.

IEC 62652-2:2026, known as the NFC Data Exchange Format (NDEF) specification, establishes a widely accepted data format for devices compliant with the NFC Forum. This specification outlines the NDEF data structure format and provides guidelines for creating a valid NDEF message, which consists of an ordered and contiguous collection of NDEF records. It also details how to designate the types of application data encapsulated within these NDEF records.

The NDEF specification focuses solely on the data structure necessary for exchanging application-specific or service-related information in an interoperable manner. It does not detail specific NDEF record types, as these are addressed in separate specifications. This specification assumes a dependable underlying protocol and does not govern the data exchange process between two NFC Forum devices.

An NFC Forum device is capable of processing NDEF information regardless of the method used to receive the NDEF message. Due to the vast array of existing message encapsulation formats, record marking protocols, and multiplexing methods, it is crucial to clearly articulate the design objectives of NDEF, especially concerning what aspects fall outside its scope.
