# Capture and check the exact value

Capture a work-order style value, preserve leading zeroes and inspect a known exact match.

## Capture and check the exact value

1. **Start capture in the focused box**

   Start capture in the focused box.

   Start capture explicitly. Only this box collects keyboard input. These keystrokes are simulated; the course does not measure a physical scanner.

2. **Scan a value with leading zeroes**

   Scan a value with leading zeroes.

   The six-character value remains text. Leading zeroes must survive unchanged; capture duration includes waiting and browser delivery.

3. **Compare with the known encoded value**

   Compare with the known encoded value.

   Use an independently known value. Copying a capture into the expectation would only prove that it matches itself. Exact match preserves every character.

4. **Inspect the captured event log**

   Inspect the captured event log.

   The log separates key and input events. The course events are simulated. Browser observations are not the original device bytes or optical decoding speed.
