If you operate as a showman, "flying trader" or owner of a market stall, i.e. if you offer your services or goods at constantly changing locations, you are operating a travel trade. For this purpose, you need a travel trade card.

The content of the travel trade permit may be restricted, it may be issued for a limited period of time and it may be subject to conditions, insofar as this is necessary for the protection of the general public or consumers. If you have a temporary travel business card, you can renew it at the competent authority.
