Inquiry about Marker-Based Talking Pen NEW

I am developing an interactive children’s book system using an OEM talking pen with micro-marker recognition. I specifically need a marker-based system with icon-sized markers (approximately 3–5 mm), not QR code or OID dot-grid solutions. Key requirements include: - Details on the marker system: supported marker types, minimum size, embedding capability, and availability of a generation tool or SDK. - Information on content mapping: how markers are linked to audio files, and if a mapping tool is provided for self-management. - Pen specifications: storage capacity, speaker quality, battery life, and USB upload functionality. - Book production options: printing capabilities for books with embedded markers and associated requirements. - Pricing for sample units: cost for 2–5 demo pens and a small demo book, as well as mass production quotes for 500 and 1000 pens, and per-unit book production.
