Product Overview

The DO-7×7-FPC-NFC is an ultra-compact high-frequency FPC NFC tag designed for space-constrained applications where small size, flexibility, and temperature resistance are critical. Measuring just 7×7 mm with a thickness of 0.05–0.07 mm, this tag integrates the NTAG215 chip operating at 13.56 MHz and is engineered to withstand high-temperature environments up to 260°C for short durations. It is an ideal identification solution for jewelry tagging, nail labels, and other small-item tracking where traditional rigid tags cannot be deployed.

As a product developed by do rfid reader manufacturer, this tag supports standard NFC-enabled smartphones and readers for fast, contactless data exchange. The combination of ultra-small footprint, flexible substrate, and heat resistance makes it suitable for industrial deployment scenarios that demand reliable performance under thermal stress.
