# 4x6 RFID Labels: The Ultimate Guide for Modern Applications ## What Are 4x6 RFID Labels? **4x6 RFID labels** represent a specific form factor of radio-frequency identification tags that measure 4 inches by 6 inches. In my experience managing inventory for a mid-sized logistics company, transitioning to this size label was a game-changer. We needed a tag large enough to hold significant human-readable information and barcodes alongside the RFID inlay, and the 4x6 dimension proved perfect for pallet and large asset tagging. The visibility and scan reliability improved dramatically compared to smaller tags we had used previously. ## Technical Specifications and Parameters of 4x6 RFID Labels When evaluating **4x6 RFID labels**, understanding the technical underpinnings is crucial. Here are detailed specifications based on common industry products. *Please note: These technical parameters are for reference data; specifics need to be contacted with back-end management.* * **Dimensions:** Precisely 4.00 inches (101.6 mm) in width by 6.00 inches (152.4 mm) in height. This is the finished label size. * **RFID Inlay/Strap Specifications:** * **Chip Model:** Often based on Impinj Monza R6 (code: R6-P) or NXP UCODE 8 (code: U8-D) for high-performance applications. Alien Higgs-3 (code: H3) is also common. * **Memory:** Typically 96-bit or 128-bit EPC memory, with optional user memory blocks (e.g., 32-bit TID, up to 512-bit user memory). * **Frequency:** UHF (860-960 MHz), compliant with EPCglobal Gen2v2 / ISO 18000-63 standards. * **Read Range:** Varies with reader and environment, but typically 5-10 meters (16-33 feet) with a standard handheld reader. * **Label Material Construction:** * **Face Stock:** Durable 4 mil (100 micron) white thermal transfer polyester (PET) or polypropylene (PP). * **Adhesive:** Permanent acrylic-based adhesive with a minimum peel adhesion of 10 N/25mm. * **Liner:** 3.2 mil (80 micron) densified kraft liner for reliable dispensing. * **Environmental Performance:** * **Operating Temperature:** -40°C to +85°C (-40°F to +185°F). * **Resistance:** Resistant to water, chemicals, and UV exposure for outdoor durability. ## My Personal Skill Development with RFID Implementation My personal journey with RFID, particularly with **4x6 RFID labels**, involved developing a niche skill: custom encoding and d
