Industry Update: Sertag Launches SETPN29_S 2.9-Inch Passive NFC E-Ink Label for Warehousing & Logistics
Sertag Launches SETPN29_S 2.9-Inch Passive NFC E-Ink Label for Warehousing & Logistics
In June 2026, electronic label manufacturer Sertag has expanded its passive NFC product portfolio with the SETPN29_S, a 2.9-inch battery-free e-ink display built for warehouse inventory, retail shelving and asset management scenarios. Engineered for ultra-low operational cost, the device draws all required power and data through near-field communication, removing the need for built-in batteries or wired power infrastructure.
Core Technical Advantages
1. Zero-battery passive NFC operation
The SETPN29_S runs entirely on energy harvested from standard 13.56 MHz NFC radio fields, with no internal battery integrated. This design eliminates periodic battery replacement and disposal, cuts long-term maintenance labor, and allows flexible installation on warehouse racks, logistics containers and remote asset locations where power access is unavailable.
2. One-tap wireless content refresh
Label content can be updated with a single tap from an NFC-enabled smartphone or dedicated reader, following a workflow similar to contactless payment. It supports multiple content formats including text, linear barcodes, QR codes and static graphics, enabling on-site staff to modify pricing, location info and material identifiers instantly without additional base station hardware.
3. High-contrast bi-stable e-ink display
The 2.9-inch monochrome e-paper panel delivers paper-like readability with a near-180° wide viewing angle, remaining legible under both indoor ambient light and direct warehouse lighting. As a bi-stable display, it holds content permanently after a single refresh with zero ongoing power draw, matching the demands of passive IoT labeling.
Key Specifications
Built around a 2.9-inch monochrome e-ink panel, the SETPN29_S delivers a resolution of 296 × 128 pixels across an active display area of 29 mm × 66.9 mm. The label has a compact physical footprint of 95 mm × 46.4 mm with a 5.4 mm thickness, suitable for mounting on warehouse bins, shelf edges and asset surfaces. It runs on the standard 13.56 MHz NFC protocol, relying entirely on passive energy harvesting with no built-in battery, and includes integrated proximity sensing. Compatible content formats include plain text, static graphics, QR codes and linear barcodes, and the device is rated for operation in temperatures from 0°C to 50°C.
Deployment & Integration Paths
Sertag offers multiple integration options to fit different operational scales:
- Custom development: Full communication protocols are provided for enterprise teams to build proprietary mobile apps or connect with existing WMS/ERP systems, with HTTP and JSON interface support for automated batch updates.
- No-code web management: For teams without development resources, the label pairs with a V4.4 controller and card reader kit, allowing template editing and content updates directly via a web browser — no local software installation required.
- Desktop batch programming: A USB card reader with serial port protocol is available for pre-deployment bulk label configuration in office environments.
Typical Application Scenarios
- Warehouse bin location markers and pallet tracking tags
- Retail shelf price labels and in-store promotion displays
- Industrial equipment and tool asset identification tags
- Reusable attendee badges for conferences and on-site events
- Package sorting and status labels for logistics and supply chain nodes
As a maintenance-free passive display solution, the SETPN29_S targets small and mid-sized operations looking to digitize their physical labeling systems without heavy infrastructure investment.
This battery-free passive NFC architecture is not limited to industrial warehousing and logistics scenarios. The same core energy-harvesting and wireless transmission technology also powers consumer-grade zero-power e-ink displays for daily use. Our White E-Ink Fridge Magnet runs on the exact same working principle: all photo and text updates are completed via NFC by holding a smartphone close to the device to deliver power and transfer content data. It requires no built-in battery, and the display retains all content permanently after each refresh cycle.
