Writable RFID Smart Card 10-Pack OSTENBIG 13.56MHz Mi‑Fare

Description

Product Overview

The OSTENBIG 10‑pack of writable RFID PVC smart cards delivers a reliable, high‑performance solution for modern access control environments. Engineered to operate at the globally recognized 13.56 MHz frequency, these cards are fully compatible with Mi‑Fare Ultralight readers and adhere to the ISO/IEC 14443A protocol, guaranteeing seamless integration with existing door access systems. Each card is fabricated from durable PVC material, providing resistance to bending, moisture, and everyday wear while maintaining a smooth surface for consistent read/write performance. With a 1 KB memory layout (16 sectors × 4 blocks), the cards offer ample space for storing user credentials, access rights, and additional data fields. The factory‑programmed unique encrypted UID (4‑byte) ensures each card starts with a secure identifier, yet remains fully reprogrammable for evolving security policies. Designed for commercial and industrial applications, the cards are lightweight (2.08 oz per pack) and conveniently packaged in a compact box measuring 5.43 × 3.31 × 0.83 in, making storage and distribution straightforward.

Usage

These writable RFID cards excel in a variety of real‑world scenarios where secure, flexible access control is essential. In corporate office buildings, facilities managers can issue cards to employees, contractors, and visitors, updating permissions instantly as roles change. Warehouses and distribution centers benefit from the cards’ rapid rewrite capability, allowing inventory managers to reassign access zones without replacing physical media. Educational campuses can deploy the cards for student ID verification, library checkout, and dormitory entry, leveraging the cards’ durability to withstand frequent handling. Healthcare facilities appreciate the cards’ ability to store patient‑specific data securely while granting staff controlled entry to restricted areas. Because the cards support a read range of 0‑10 cm, they work effectively with standard proximity readers placed at turnstiles, door hinges, and gate barriers, delivering a smooth user experience across diverse environments.
