YINGMI C7S Dual-Mode Smart Guide System
Tap to Listen. Walk to Learn. The Future of Hands-Free Exploration.
Overview: Intelligence at Your Fingertips (and Footsteps)
The YINGMI C7S is a revolutionary neck-mounted guide system that combines two intelligent technologies for the ultimate flexible touring experience. It features both NFC Tap-to-Listen and Automatic RFID Induction, allowing venues to choose the perfect interaction mode for any exhibit layout—from densely packed galleries to expansive open spaces.

1. NFC Tap-to-Listen Mode (For Precision)
Ideal for museums, art galleries, and exhibitions with closely spaced items.
-
How it works: A discreet NFC tag card is placed next to an exhibit. Visitors simply tap the lower end of their C7S device to the tag to instantly hear the dedicated commentary.
-
Key Benefit: Eliminates signal overlap. Provides pinpoint accuracy, giving visitors full control to choose what to listen to and when, with no interference from neighboring exhibits.
2. Automatic RFID Induction Mode (For Flow)
Perfect for scenic spots, historical routes, and open-plan exhibitions.
-
How it works: Small RFID transmitters are installed at points of interest. The C7S device automatically senses the visitor's location and plays the corresponding audio, then stops as they move away.
-
Key Benefit: Creates a seamless, hands-free narrative journey. The story unfolds naturally as the visitor walks, requiring no interaction.
Key Features & Benefits
-
Fast & Easy Content Management: Update or upload thousands of MP3 audio files quickly via USB. Digital storage ensures perfect, distortion-free audio quality.
-
True Multi-Language Independence: Each visitor selects their language at the start. Both NFC tap and auto-induction modes will deliver commentary in their chosen language simultaneously within the same space.
-
Reliable & Clear Audio: Operates on a dedicated 860MHz-870MHz frequency band with advanced anti-interference technology, guaranteeing a clear, low-noise listening experience even in crowded venues.
-
All-Day Power: With an 800mAh battery and low-power design, the C7S provides over 10 hours of continuous use, easily lasting through a full day of tours.
-
Comfortable Design: The lightweight (50g) neckband is comfortable for extended wear, putting the focus on the experience, not the device.
