Stack · Pair · Grade
Drop a scanner stack — Fujitsu fi-8170 duplex is front then back, then the next card. Files named front/back or f/b on the same stem stay together; otherwise we pair 001 with 002, 003 with 004. If a card cannot be named, we stop and ask — same picker as a single scan. Then you can print sleeve labels or send the serials to TCSell.

Up to 33 cards — one HERMA 4613 sheet. Prefer IMG_001 + IMG_002, or the same name with front/back.
