OASIS exclusion check: meeting the query duty simply and completely

What is the OASIS exclusion register?

OASIS is Germany's nationwide player-exclusion system under §§ 8 ff. GlüStV 2021, operated by the Regierungspräsidium Darmstadt. The register lists all players who have excluded themselves or been excluded by third parties. Gambling operators must check before play whether a guest is excluded — excluded persons must be denied access to gambling.

Who must run the OASIS check?

The query duty applies wherever licensed gambling takes place:

• Gaming halls — at every admission
• Hospitality venues with gaming machines — before play
• Betting shops and betting agencies — before a bet is placed

How the exclusion check works

1. 1

   Check ID

   Establish the guest's identity and age using a valid ID document.

2. 2

   Query OASIS

   Check name, date and place of birth against the exclusion register — the result arrives in seconds.

3. 3

   Act on the result and document it

   No match: play may proceed. Match: deny access to gambling. Either way, the check must be properly documented.

The exclusion check as access control

In practice the OASIS check is the core of access control: it decides who may play. Anchoring the check firmly at the entrance not only fulfils the legal duty — it protects vulnerable guests and shields your staff from liability risks.

The OASIS app turns the duty into a routine

The Ardanto OASIS app guides your staff through ID check and exclusion query and documents every result automatically — per venue, audit-proof and reusable for the social report. Runs on any smartphone or tablet, no extra hardware required.
