Two questions, one upload. Is this thing registered? Photograph the pack — start with the front, square-on, filling the frame; owners can sign the back and top too, so whichever side faces you can match. Is this media registered? Any photo, video or audio is checked for its Ehopto signature. Fingerprinted on the spot — nothing is stored.

A loose tablet has three clues built in: the imprint (letters or numbers pressed into it — the strongest one), its shape, and its colour. Possible matches only — always confirm with a pharmacist.
