Authorisation card

Your authorisation card indicates which types of combat you're authorised to compete in within the SCA. The list keeper must check this before you can enter a tournament, and you must have one of these to participate in any type of combat. The exception is if you are training for authorisation, in which case your kingdom may require you to have a 'training card' and be under the guidance of an authorised combatant or a marshal.

Authorisation cards are also used for marshals and other officers to indicate that they have met the minimum standard/qualifications for the office and are sanctioned to undertake the activities of that field, e.g. first aid for a chirurgeon.
