Submitted is a major revision of the existing Arizona House Bill 2005, which uses a specific in-app payment system as an exclusive means of user payments to developers residing in Arizona. The content is that it is prohibited to request. It also protects users in Arizona from making payments with an exclusive payment system.

The bill does not name a specific app store, but it is believed to target the App Store and Google Play, which require access to the store's payment system. Retribution to developers who did not use the store's payment system is also prohibited, but online stores for game consoles and music players are excluded.

The bill was passed 31-29 at a parliament meeting held on March 3, 2021. However, it is still uncertain whether it will be state law, as there will be a subsequent Senate vote, and if it is passed, Governor Doug Ducey can decide whether to dismiss it.

App store payment fees are also one of the causes of the legal battle between Fortnite developer Epic Games and Apple and Google.

Apple and Google have not commented on this matter.
