It'd be the same mechanism as other rapid tests. After a person swabs their nose with rhinoswab, detach the swab ends and put them in a tube prefilled with a reagent. Shake the tube for about 30 secs. The tube has two caps: one with a larger hole to put the swabs in, and the other is a small end with a pipette like shape. Open the pipette end and drop the reagent onto a test card. Wait for 15 minutes. If positive, a tape on the card will change color.
