The European Union antitrust regulators have opened two investigations against Apple regarding the activities of the App Store and the Apple Pay, saying that restrictions imposed by the iPhone manufacturer may violate EU competition rules, Reuters reported.

According to the European Commission, one investigation would look into the mandatory use of Apple’s in-app purchase system and rules preventing app developers from informing iPhone and iPad users of cheaper options elsewhere. 

The second case focuses on Apple’s terms and conditions on how its payment service Apple Pay should be used both in merchants’ apps and websites and the company’s refusal to allow opponents access to the payment system.
