Container Inspection Software & Mobile Evidence Layer | ConPDS Checker
The structured workflow that captures every inspection, repair, lease return, and PTI record on a standard smartphone, links it to the ISO 6346-validated container number at the point of capture, and retains it under the operator's retention and access controls — replacing WhatsApp threads, mail attachments, and shared drives with the defensible record a contested repair charge or lessor audit is settled on. Read the foundational definition →
ConPDS Checker is the mobile evidence layer for container operations — capture inspection, repair, lease return, and PTI evidence on iOS or Android, validated against the container number via ISO 6346 OCR at the moment of capture, and pushed into AEMS, DepotMaster, EOS, IMARS, OVMR, FIS, or any Custom API. Built for the depot, reefer workshop, wash station, and shipping-line operations that carry the financial and audit consequence of how container documentation is run.
What it costs operations to run inspection records informally
Container depots and service facilities handle large volumes of inspections, repairs, and lease returns every day. The yard work is structured. The evidence layer underneath it usually is not — and that informality lands as written-off repair charges, failed audits, and disputes nobody can defend.
In many facilities, the inspection record is
The financial and audit consequence
A Structured Container-Based Evidence Workflow
ConPDS Checker replaces informal photo handling with a structured evidence workflow built specifically for container operations — from field capture, through ISO 6346 validation and central retrieval, to structured distribution into the depot, M&R, and shipping-line systems the operation already runs.
Capture Inspection and Repair Photos in the Yard
Field workers use the ConPDS Checker mobile app on their existing smartphones or tablets. Photos are taken during damage inspections, repair documentation, container damage documentation workflows, lease return condition reports, and pre- and post-repair checks. No additional hardware is required.
The app also supports short video clips (up to 30 seconds) and audio capture for inspections where motion or sound verification is required. All media is linked to validated container numbers and logged in the same audit trail as photo captures — providing structured multimedia evidence in a single container record.
Automatic Container Number Recognition
The system reads and validates the container number directly in the app using AI-powered OCR with ISO 6346 container number validation — ensuring photos are always linked to the correct container record. Images are automatically tagged and stored at the point of capture, eliminating manual renaming and reducing documentation errors at scale.
Immediate Web Dashboard Access
All photos are available instantly in the browser-based dashboard. Office staff can search by container number, review inspection documentation, organise repair cases, and share documentation with customers or agents. Everything is centralised and searchable.
Integration With Depot Management Systems
ConPDS Checker integrates with existing depot management and maintenance systems to ensure documentation is connected to your operational flow — not running in parallel to it.
Why Informal Tools Fail as the Evidence Layer
Messaging apps and shared drives are fast and familiar. They are also invisible to audits and unrecoverable under dispute. The short version:
Informal photo handling as the de-facto record
ConPDS Checker as the structured evidence layer
What Adding the Evidence Layer Actually Changes
ConPDS Checker does not replace your depot management system or your M&R workflow. It adds the structured photo and metadata evidence layer that DMS, AEMS, and DepotMaster do not natively carry — the layer that turns repair-claim defence, audit production, lease return handover, and reefer PTI into a reproducible record. The yard work stays the same; the record under it becomes defensible.
Built to Fit Your Operation
Depot, reefer service, wash station, independent M&R — the operation shapes the documentation workflow, not the other way around. ConPDS Checker adapts to your facility type, operational scope, integration stack, commercial setup, and rollout cadence.
In the yard. OCR at the moment of capture.
Field workers open the Checker mobile app, photograph the container, and the system reads the ISO 6346 container number directly from the image — validating the check digit and linking every photo to the correct container record before it leaves the device.
Back at the office. Any container, any case, in seconds.
Office staff search the central archive by container number, date range, or status. Filters narrow results instantly. Each case shows the full photo set with one-click actions for tagging, plate matching, and bulk distribution.
When a dispute arrives. Tamper-evident evidence, ready in seconds.
Open any photo to inspect at full resolution. The container number and timestamp are burnt into the image itself — tamper-evident at the file level, not just in metadata. Add notes, comments, or actions; adjust brightness and contrast for clarity; share without losing the audit trail.
Used in Active Container Environments
ConPDS Checker is used by container depots and service facilities across Europe, Africa, Australia and the Middle East to structure inspection and repair documentation workflows. Built by professionals with direct experience in container depot operations, field-tested since 2013 and continuously refined based on operational feedback.
ConPDS is the best app for photographing and organizing container photos — and their support is outstanding!

Frequently Asked Questions
Put a defensible evidence layer under your inspection, repair, and lease return work
If your operation runs daily inspection, repair, lease return, or PTI work, the question is no longer whether to digitise — it is whether the record underneath the operation is defensible when a contested charge, an audit, or an off-hire claim arrives. ConPDS Checker is the layer that makes it so.
