The European Commission says it’s made commitments offered by Apple in January legally binding, allowing third-party developers to use the NFC functionality on iOS devices without being tied to Apple Pay or Apple Wallet.

The acceptance officially settles a four-year EU investigation and spares Apple from facing fines of up to $40 billion. EU competition chief Margrethe Vestager said:

“It opens up competition in this crucial sector, by preventing Apple from excluding other mobile wallets from the iPhone’s ecosystem.”
