In-person responses

Number Cards

Collect 1–5 ratings in the room with reusable cards and a phone camera.

Give each person a five-card set. When they hold up a number, the scanner reads the corner tags and adds their person number and response to a table.

When to use them

Before and after training
Ask the same confidence question at the start and finish. Keep the same sets so you can compare responses by person number.
Quick room polls
Ask for a rating, a vote between numbered options or a check on how well the group understands a topic.
Live results alongside slides
Pair the scanner with a presentation to show the room’s responses and mean while you scan.
