Overview
EN 16656:2014 (CEN adoption of ISO/IEC 29160:2012, modified) defines the RFID Emblem - a public-domain visual identifier that notifies users of the presence of radio frequency identification (RFID) on items, labels, readers and equipment. The standard specifies emblem representations, minimum sizes, clear space, and the optional RFID Index: a two‑character code that conveys the tag/interrogator frequency, air‑interface protocol and data structure. Placement specifics are not prescribed; application standards or implementers should determine location on labels or products.
Key Topics and Requirements
- RFID Emblem design: Two visual variants (dark‑on‑light and light‑on‑dark). The emblem must not be modified and may be engraved, embossed or printed.
- Minimum size and clear space: Recommended minimum 14 mm × 13 mm with a 3 mm unprinted area; direct‑marking exceptions permit a minimum 5 mm square.
- RFID Index (two‑character code):
- First character: frequency range, air‑interface protocol and defining authority.
- Second character: data structure identifier.
- A generic code with an asterisk (*) is assigned per grouping for interrogators only (not for labels/tags).
- Use conditions: Emblem is free to use without fees; users self‑certify compliance with assigned codes (Table A.1). Ad‑hoc/internal two‑character assignments are prohibited.
- Maintenance and registration: Requests for new index assignments use the form in Annex C and are submitted to ISO_IEC_29160_RegistrationAuthority@aimglobal.org. Criteria include stable standards, recognized issuing bodies and demonstrable need.
- Supporting material: Annex A lists assigned codes; Annex B contains emblem drawings; Annex D discusses other industry markings.
Applications and Who Uses It
- Manufacturers of RFID tags, labels, printers/encoders and interrogators - to mark products and equipment clearly.
- Retailers, logistics and supply‑chain operators - to inform staff and consumers about RFID presence and help selection of compatible reading equipment.
- System integrators and installation planners - to ensure interrogators are suitable for the frequency/protocol/data structure indicated by the RFID Index.
- Product designers and consumer privacy advocates - to provide visible notification of RFID on consumer goods.
- Standards developers and regulators - to harmonize emblem use and incorporate placement rules into application‑specific standards.
Related Standards
