Indemnify This is a professional tool for ski maintenance technicians and shop managers who need to quickly verify whether a ski binding is on the current indemnification list. Instead of flipping through printed PDFs or searching dense spreadsheets, import your shop's indemnification list once and get instant searchable access to every binding on it. HOW IT WORKS Import your shop's NSSRA Combined Indemnified Bindings List or manufacturer PDF The app parses the document and builds a searchable database on your device Look up any binding by brand or model name in seconds Use the camera to photograph a binding — OCR reads the text and suggests matches Tap any result to see full details and links to reference images BUILT FOR THE SHOP FLOOR Works offline — no internet needed after import All data stays on your device, never uploaded or shared Supports NSSRA combined lists, Marker retail/rental lists, and similar manufacturer PDFs Filter by brand, search by model, see current vs non-current status at a glance Import a new PDF each season to stay current CAMERA IDENTIFICATION Point your camera at a binding's label or markings. The app uses on-device text recognition to read brand names and model numbers, then cross-references your imported list to suggest matches ranked by confidence. Indemnify This does not include binding data — it is a tool for use with your shop's own purchased indemnification lists. A valid NSSRA membership or manufacturer dealer agreement is required to obtain the lists used with this app. Always verify indemnification status against official manufacturer documentation before servicing any binding.
