Product Overview
The DO-12FPC-D23 high-frequency flexible FPC NFC tag is a compact, durable RFID inlay engineered for access control, public transit, and secure identification systems. With a diameter of just 12 mm and an ultra-thin 0.08 mm profile, this tag integrates the MIFARE DESFire EV1 D23 chip, operating at 13.56 MHz under the ISO 14443A standard. Designed for projects requiring long-term reliability and high-temperature resistance, this NFC tag is a preferred choice for system integrators and industrial buyers who need stable performance in confined spaces or harsh environments.
Key Features
- Ultra-compact 12 mm diameter — ideal for space-constrained installations such as smart rings, key fobs, small asset tags, and embedded access credentials.
- Flexible FPC substrate — conforms to curved or irregular surfaces without compromising antenna performance or read reliability.
- MIFARE DESFire EV1 D23 chip — supports triple DES and AES encryption for secure access control and payment-grade applications.
- High-temperature tolerance — withstands 150 °C for 2 hours and 200 °C for 3–5 minutes, enabling integration into industrial manufacturing or automotive processes.
- 2 kB memory — flexible data storage with sector-level access control and support for multiple applications on a single tag.
- 25-year data retention and 200,000 write cycles — built for long-term deployment without frequent replacement.
- True anti-collision — allows multiple tags to be read simultaneously in a field without data corruption.

Industrial Applications
This tag is deployed across multiple commercial and industrial sectors where small size, security, and environmental resilience are critical. Common applications include:
- Access control systems — used in office buildings, parking facilities, and restricted areas where secure credential verification is required.
- Public transportation — integrated into contactless fare cards, wearable bands, and ticket tokens for metro, bus, and toll systems.
- Electronic toll collection — embedded in windshield stickers or vehicle tags for automated fee deduction at high-speed checkpoints.
- Campus and facility management — student ID cards, staff badges, and visitor passes requiring encrypted data storage and fast read times.
- Industrial asset tracking — attached to small tools, components, or consumables where space is limited and exposure to heat or chemicals is possible.
- Secure identification — anti-counterfeiting labels for high-value products, brand protection, and supply chain authentication.
Product Advantages
System integrators and procurement teams choose this tag for several practical reasons. The 12 mm form factor allows embedding into products where larger tags simply do not fit — such as smart rings, thin plastic cards, or metal-framed access tokens. The FPC flexible substrate ensures the antenna maintains its tuning even when bent during installation or normal use. The MIFARE DESFire EV1 D23 chip provides enterprise-grade encryption, making it suitable for payment and identity applications that require compliance with industry security standards. The wide operating temperature range and short-term heat resistance enable deployment in environments like powder coating lines, injection molding, or automotive assembly where thermal exposure is unavoidable.
OEM / ODM Manufacturing Support
As a dedicated do rfid reader manufacturer, we offer complete OEM and ODM customization for this NFC tag. Buyers can specify custom chip encoding, antenna tuning for specific substrates, printed branding or serial numbering, and custom packaging formats (reel, roll, sheet, or individual blister). We support bulk purchasing with consistent batch-to-batch performance, ensuring each tag meets the same electrical and mechanical specifications. For project deployment involving thousands or millions of units, we provide pre-personalization services including UID locking, application data pre-write, and security key injection at the factory level.
Factory Production Advantages
Our manufacturing facility is equipped for large-scale production of flexible FPC tags with strict process control. We maintain stable production capacity year-round, enabling us to fulfill wholesale orders and long-term supply agreements without interruption. Every production lot undergoes in-line testing for resonance frequency, read range, and data integrity. This level of process control directly supports system integrators and distributors who require batch consistency across multiple project phases. Our fast lead time — typically 1–7 days for samples and 7–20 days for mass production — helps buyers meet tight deployment schedules without compromising on quality or compatibility with existing systems.
Bulk Supply & Project Deployment Support
We work directly with wholesale buyers, distributors, and industrial solution providers who need a reliable supply chain for ongoing RFID projects. Whether you are deploying access control across a multi-site enterprise, integrating NFC into a consumer product line, or upgrading a transportation fare system, we offer volume pricing, scheduled shipments, and technical support throughout the product lifecycle. Our commercial applications expertise means we can recommend the right chip configuration, antenna design, and packaging format for your specific use case — reducing trial-and-error during integration.
