Ultra-Black Light-Absorbing Film for Anti-Glare QR Codes

Challenge

Outdoor QR code scanning—especially for parking lot payment systems—frequently fails under direct strong sunlight. Intense glare and reflection cause QR codes to appear washed out, blurring black-white contrast and making recognition impossible. Users are forced to exit vehicles and scan at close range, severely reducing operational efficiency and user experience.

Solution

Suzhou Tsingcarbo Nano Materials Co., Ltd. has developed an anti-glare QR code solution using its proprietary ultra-black light-absorbing film, engineered on its core nanoporous carbon technology. Unlike conventional reflective QR code substrates, this film actively absorbs strong incident light rather than reflecting it, preserving sharp black-white contrast even in harsh midday sunlight.

Key Performance

Instant Recognition: Scans successfully in 0.01 seconds under direct midday sun, with zero interference from glare or reflection.

Superior Contrast: Maintains crisp, high-contrast QR code patterns for reliable long-distance scanning.

Broad Compatibility: Easily applied to outdoor billboards, parking barriers, in-vehicle devices, and other outdoor/strong-light scenarios.

Result

This light-absorbing QR code solution eliminates the “glare failure” issue entirely. Parking lot operators achieve faster, smoother payment processing with no need for manual intervention, while users enjoy a seamless, touch-free scanning experience—even under the brightest outdoor conditions.

Ideal For

Parking lot access & payment systems

Outdoor advertising & information boards

In-vehicle QR code displays

Public facilities & smart terminals exposed to strong sunlight
