What it leaves behind
Templates, override logs, retention, leavers, and what the records will support when asked.
What the Record Will Support
A biometric read is stronger evidence than a card swipe and weaker than people assume. Knowing the weight of each entry prevents it being overloaded.
The Override Log as a Management Figure
One monthly number tells you whether enrolment is degrading, whether a terminal is failing, and whether a department has been abandoned by the system.
How Long Any of It Is Kept
Three different kinds of data with three different retention answers, all set by a default in a configuration screen that nobody has opened.
The Template That Should Have Gone
Deleting a leaver's biometric data is a two-minute task on nobody's list, which is why most systems hold templates for years of former staff.
Taking a Reader Out
A terminal that is replaced, returned under warranty or sold on may be carrying the templates of everybody who ever used it, and nobody checks.
What Gets Asked For
Inspectors, representatives and individuals ask for the same handful of things, in roughly the same order, and most sites can produce about half of them.
What a Working Arrangement Looks Like
A description to compare yours against. Nothing in it requires new equipment, and most of it is a list that was written down and a setting somebody decided.
