Overview
IEC 63563-8:2025 - Qi Specification version 2.0, Part 8: NFC Tag Protection provides guidelines for detecting the presence of RFID tags and NFC cards within the operating range of a wireless Power Transmitter and for preventing damage to those tags or cards. Published by the IEC and based on the Wireless Power Consortium (WPC) Qi v2.0 NFC Tag Protection document, this standard addresses integration, detection procedures, and test methods to safely co‑exist wireless charging (Qi) and NFC/RFID functionality.
Key Topics
- Scope & Compliance: Clarifies that provisions are mandatory unless marked otherwise and follows ISO/IEC directives for normative language (shall/should/may).
- NFC tag detection: Methods for detecting passive NFC/RFID tags using dedicated NFC hardware or by leveraging power‑transfer signals.
- Antenna and transceiver integration: Guidelines for integrating an NFC antenna and NFC transceiver into Power Transmitter products to ensure reliable detection and minimal interference with wireless power transfer.
- Polling and detection modes: Procedures for NFC polling and recommended detection sequences during both standby and active power-transfer phases (including low‑power detection).
- Power Receiver considerations: Design guidance and recommended detection procedures for Power Receiver products to help protect nearby NFC tags.
- Test methods: Definition and construction of a Test PICC (test NFC card) including calibration and a stepwise test procedure to evaluate the impact of a Power Transmitter on NFC tags.
- Documentation & references: Cross‑references to WPC resources, Electropedia, and IEC publication tools.
Applications and Who Uses It
This standard is intended for:
- Wireless charging device manufacturers (Power Transmitters and Receivers) integrating Qi wireless power with NFC coexistence.
- Hardware and antenna designers working on coil layouts and NFC antenna placement.
- Test labs and compliance engineers performing NFC tag protection testing using the Test PICC procedures.
- Product managers and systems architects ensuring products meet safety and interoperability expectations when NFC cards may be present on charging surfaces.
Practical applications include preventing data loss or physical damage to contactless payment cards, access badges, transit cards, and other RFID/NFC tags placed on or near wireless chargers.
