OEM SD-CS Mifare 13.56MHz Adhesive Coin Card

SD-CS Mifare Sticker

The OEM SD-CS Mifare Card operates as a passive 13.56MHz RFID transponder designed for high-frequency access control and asset tracking. This device integrates a standard Mifare Classic 1K chip into a compact circular form factor. The design includes a high-tack 3M adhesive backing for deployment on mobile devices or existing identification badges. It utilizes the ISO/IEC 14443 Type A air interface protocol to ensure compatibility with standard proximity readers. The internal antenna design optimizes energy harvesting from the reader field for consistent data transmission. This hardware provides a reliable solution for contactless identification without requiring a full-sized plastic card.

Key Features

• Frequency and Protocol Compliance

Why Choose SD-CS Mifare Sticker

• The 13.56MHz frequency ensures rapid data processing and high collision resistance for multiple tag environments.

• The compact 25mm form factor allows for seamless integration onto existing equipment without obstructing user interfaces.

• Industrial-grade 3M adhesive maintains a secure bond even under varying thermal conditions and mechanical stress.

• Standardized ISO 14443A compliance guarantees interoperability with a wide range of commercial smart card readers.

• Robust PVC housing protects the internal RFID circuitry from moisture ingress and physical impact during daily use.

• However, mounting this specific tag directly onto metal surfaces will significantly degrade the electromagnetic read range.
