What ON-AX builds

Technology development, data refinement and management, and core technology for integrated systems. All three are running today in SELL-PHONE and the overseas auction system.

Technology development

ON-AX designs and builds the whole service itself, from screens to servers and operations tools.

  • Diagnostics integrationApp results read item by item, straight into pricing
  • Deadline alertsStaff are alerted before a step runs late

Data refinement and management

Data created in operation follows a fixed path, from the moment it arrives to the moment it is deleted.

  1. CollectOnly what is needed; research is opt-in
  2. ValidateFiles checked by real content
  3. RefineLocation, time and device data removed
  4. SeparateUnlinked from the application

How SELL-PHONE is built

Under the seven steps a customer goes through, four systems work together. ON-AX builds all of them.

  1. Apply
  2. Function check
  3. Photo capture
  4. Grading
  5. Final price
  6. Shipping & payout
  7. Data erasure
  • Customer appsWeb and app sign-up, remote checks, accepting the final price, progress alerts
  • InspectionDiagnostics app integration, six-side capture, review queue with second grading, time-limit alerts
  • PricingVersioned price tables and deduction rules — the same condition gets the same price
  • Data protectionEncrypted phone numbers and IMEIs, scheduled deletion of photos and video, a record of every action

Grading-data research

ON-AX uses the grading records produced in operation to research technology that assists appearance grading. No step is skipped.

  1. Consented recordsOnly appearance photos and grades that customers opted in to share. No video, phone numbers or IMEIs.
  2. We are hereSeparated from applicationsWhen the photo retention period ends, records are de-identified and stored separately.
  3. Grading-assist researchResearch into telling appearance conditions and damage types apart.
  4. Side-by-side validationResults are compared against inspectors’ grades until they agree consistently.
  5. Gradual adoptionOnly validated areas are used, and only to assist inspectors.

How ON-AX works

  • People grade firstUntil the technology is validated, inspectors decide every grade. Some grades are re-checked by a second inspector to keep the standard steady.
  • Collect only what is neededResearch uses consented photos and grades only. Anything that identifies a person is separated, and deleted when its period ends.
  • Record every actionStatus changes, personal-data access, grading and deletion are logged so they can be checked later.
