While Apple was showing off its new credit card, the Apple Card, at a splashy event on Monday, it was also quietly making changes to its Apple Pay Cash feature.
Apple Pay Cash is a peer-to-peer payment feature that lets you send and receive money through iMessage.
The feature also puts a digital card in your iOS Wallet app to use for purchases in real life.
You can add money to the digital card as well.
On Monday, Apple stopped allowing users to send person-to-person payments using a credit card, according an Apple Insider report on Tuesday.
The updated terms of service for Apple Pay Cash, which is provided by Green Dot Bank, now say: "Credit cards are not Supported Payment Cards and therefore cannot be used to fund a P2P Transfer or to add funds to your Apple Pay Cash Card."
