Data Architecture
Every Column Counts
Precision is the protocol
Each of 80 columns holds exactly one character — no ambiguity, no interpretation, no exceptions.
The format is the contract
Standardized dimensions mean any reader, any sorter, any program processes the data without translation layers.
Errors leave a permanent trace
A misplaced hole is a permanent record on the card — integrity is enforced by the medium itself.
Scale demands rigidity
When millions of cards flow through a system, every formatting decision becomes an institutional guarantee.
