ISO/TS 7352:2023 relates to NFC and QR code seals used with freight containers. Posttech manufactures laser-marked metal QR code tags that can be considered as durable physical identification components for freight-container, logistics and related industrial QR code applications.
Our metal tags can carry QR codes, Data Matrix codes, barcodes, serial numbers and other variable identification data on stainless steel, aluminium and titanium substrates.
ISO/TS 7352:2023 addresses NFC and QR code seals for freight containers. It concerns the broader identification and seal system rather than prescribing a particular Posttech tag material or manufacturing method.
For companies evaluating QR-based identification for freight containers, the standard provides an important technical context for how QR or NFC information may be incorporated into container-seal systems.
Posttech uses laser marking to produce permanent machine-readable identification on suitable metal substrates. The QR code, barcode or Data Matrix can be generated from customer-provided serial data or produced as part of a variable-data serialization project.
Important design factors include tag dimensions, code size, data length, scanner distance, surface finish, contrast, mounting position and the expected operating environment.
Stainless steel is a durable general-purpose option for industrial, outdoor and long-life identification applications.
Available with QR codes, barcodes, Data Matrix codes and serialized variable data.
Aluminium, also commonly searched as aluminum, provides a lightweight option for identification plates and QR code tags.
Anodized aluminium can be selected where low weight and permanent laser-marked identification are important.
Titanium may be considered for specialized applications where its low weight, corrosion resistance or material-specific properties justify its use.
Suitability should be validated against the actual operating and mounting conditions.
A QR code seal and a metal QR identification tag are not necessarily the same thing. ISO/TS 7352:2023 concerns the overall QR/NFC seal application for freight containers.
A Posttech metal QR tag may form one physical identification component within a broader container identification or seal implementation, depending on the system design.
