Dual-Sided Scanning with Grace & Comfort

0.9 Badge Holder was developed to minimize thickness while maintaining durability. A single piece of 0.7 mm vegetable-tanned leather is combined with a 0.2 mm environmentally friendly TPU film. Through internal structural optimization, material layering is reduced to achieve a total thickness of only 0.9 mm, creating a lightweight and comfortable wearing experience.

The modular system allows users to expand storage when needed. Detachable pockets provide space for small daily items such as coins, keys, stamps, or earbuds.

An expansion ring enables additional modules to be attached without altering the main structure, maintaining flexibility while preserving a clean form.

Dual-Sided Scanning with Zero Interference

To ensure reliable performance, the badge holder integrates RFID-blocking film with anti-interference sleeves. This layered structure allows both sides to be scanned independently while preventing signal conflict between cards. The result is smooth, stable scanning without cross-interference.

The 0.9 Badge Holder is crafted from sustainable materials, including Florentine aniline-dyed vegetable-tanned leather and environmentally friendly German leather fiber. The material selection supports durability while maintaining a refined appearance and tactile quality.
