Product Overview

The 14mm diameter FPC NFC tag is a compact, high-frequency RFID solution designed for space-constrained applications requiring reliable contactless identification. Built around the MIFARE DESFire EV3 D43 chipset, this tag operates at 13.56 MHz and complies with ISO/IEC 14443-2/3 A standards, making it suitable for secure access control, electronic toll collection, public transit ticketing, and campus card systems. This tag is manufactured using flexible FPC (Flexible Printed Circuit) substrate material, allowing integration into curved surfaces, small enclosures, or embedded within existing equipment without compromising mechanical reliability.

System integrators, access control contractors, tolling system operators, and public transit authorities choose this tag when they require a miniature form factor combined with industrial-grade data security and memory capacity. The 14mm diameter enables deployment in key fobs, wearable credentials, embedded modules, and small-form-factor identification tokens where standard 25mm or larger tags cannot fit. For distributors and wholesalers managing large-scale campus card or transit ticketing projects, the consistent read performance and batch-to-batch reliability of this tag reduce field failures and rework costs over the deployment lifecycle.

Product Advantages

Space-optimized design for constrained deployments — The 14 mm diameter allows integration into small-form-factor credentials, wearables, and embedded modules where standard 25 mm or 30 mm tags cannot fit. This is critical for transit token manufacturers, access control credential producers, and device OEMs requiring a miniature identification component that does not compromise read performance or data security.

Industrial-grade data security — The MIFARE DESFire EV3 D43 chip provides AES-128 encryption with mutual authentication, making it suitable for applications requiring secure transaction processing, such as electronic toll collection, prepaid transit ticketing, and restricted-access campus cards. System integrators handling sensitive payment or identity data benefit from proven chip-level security that meets industry compliance requirements.

Reliable performance in demanding environments — With an operating temperature range of −20 °C to +85 °C and short-term resistance to 200 °C, this tag supports integration into products that undergo high-temperature manufacturing processes such as overmolding, lamination, or potting. Distributors supplying tags for industrial asset tracking or outdoor access control can depend on stable read performance despite temperature fluctuations.

High write endurance for frequent-use applications — Rated for 1 million write cycles, this tag is designed for systems where credentials are repeatedly read and updated, such as transit fare collection, parking access, or cafeteria payment systems. Wholesale buyers supporting high-traffic deployments benefit from reduced tag replacement frequency and lower total cost of ownership over the project lifecycle.

Industrial Applications

• Public transit ticketing — Contactless fare collection for buses, trains, and metro systems requiring secure stored-value transactions with fast read times
• Access control — Employee credential cards, visitor badges, and secure area entry for commercial buildings, government facilities, and industrial sites
• Electronic toll collection — Vehicle-mounted tags for automated toll payments on highways and bridges, requiring reliable read performance at short distances
• Parking management — Entry and exit credentials for gated parking facilities, with support for prepaid and pay-per-use models
• Campus card systems — Multi-function student ID cards combining building access, library borrowing, cafeteria payment, and printing services in a single credential
• Event ticketing and loyalty programs — Wristbands or key fobs for concerts, exhibitions, and membership programs requiring secure token-based access
• Industrial asset tracking — Small equipment identification tags for tool tracking, IT asset management, and inventory control in manufacturing and logistics environments
• Embedded OEM modules — Integration into consumer electronics, medical devices, and industrial equipment requiring NFC-based commissioning, configuration, or user authentication
