LATAM context
Pure digital statements almost never need ICR, but physical bank forms or legacy documents with handwritten notes are where ICR makes the difference between extracting the data or not.
Concrete example
A branch deposit voucher with a hand-written amount gets processed with ICR to pull the amount out as digital, numeric data.
How it shows up on your bank statement
Like OCR, ICR is part of the processing, not something that shows up in the document itself. It becomes relevant when a statement carries handwritten notes (a received-by signature, a margin note from an accountant) that printed-text recognition can't read.
How does finO$ handle this?
finO$ uses ICR in edge cases when it detects handwritten areas on scanned documents.
