What should the tourist do after completing the procedure inside the store?

The tourist must keep their sales receipt along with the Tax Free tags, and get them validated within 90 days and just before they leave the UAE.

Since the validation process takes a couple of minutes, the tourist must arrive earlier at the airport, or land/sea border crossing earlier to complete the procedure. Before they check in their luggage and go through security, they need to get their Tax Free tags validated by either a Planet staff member or one of the self-service kiosks.
