Overview
One UHF + NFC dual RFID inlay for the warehouse and the phone
The ID-4020-EM4425 is a 40 × 20 mm inlay built on the EM4425 chip, which has two radio interfaces. The UHF side works with standard EPC Gen2 readers across 860–960 MHz, including India's 865–868 MHz band. The NFC side works at 13.56 MHz, so an NFC-enabled smartphone can read the same tag with a tap. One tag can then be counted in the supply chain and checked by a customer or field staff without a dedicated reader.
Plan for close-range reading
The listed read range is up to 0.5 m. Treat it as a close-range tag: UHF reads at a packing table, desktop reader or handheld held near the item, and NFC at tap distance. For long-range dock-door or portal reading, choose a standard UHF label from our UHF RFID inlays and labels range.
Where a dual inlay is useful
- Product authentication: the brand checks goods by UHF in the warehouse, and the buyer taps the pack with a phone to verify it.
- Packaging engagement: the NFC side can be set up to open a product page, user manual or registration form.
- Service and returns counters: staff confirm an item's identity with a phone instead of a UHF reader.
