Match repeated information
Compare names, dates, document numbers and other repeated fields exactly as the current reference and policy direct.
Review design continuity
Consider whether front and reverse layouts, materials and information structure form one coherent document rather than two isolated surfaces.
Treat machine-readable data as one signal
If an approved tool is used, compare its result with visible information; a successful read does not independently establish authenticity.
Build a cross-side field map
Training material can identify which visible fields repeat, which are encoded or represented differently and which appear on only one side. Reviewers should use the map for the exact document type rather than expecting every jurisdiction to follow the same pattern. When a value cannot be compared, record the limitation instead of assuming inconsistency.
Check physical continuity
Observe whether edges, materials, orientation and design transitions are coherent from front to reverse under normal handling. Compare with a current reference and account for wear. Physical continuity is one part of the complete review; it does not replace checking personalized information, date fields, portrait presentation or the organization’s other required steps.
Handle encoded data responsibly
Use a scanner only when approved and necessary. Compare relevant returned values with visible fields, note unreadable results without treating them as proof and prevent unnecessary storage or display. A machine-readable area can be copied or damaged, so the tool result must remain one observation within a broader trained inspection and privacy-controlled workflow.
Complete the cross-side review
Use a current field map, compare repeated values and observe physical and design continuity without expecting every format to match local conventions. If scanning is authorized, keep its output subordinate to the complete review and apply privacy controls. Route unresolved inconsistencies with precise observations so the next reviewer can assess both sides without inheriting a conclusion.
