Riders who tag their card at a recently synchronized payment collection device will have their card updated to reflect their true account balance. The waiting period between synchronizations may cause some cards to report lower funds than are actually on the corresponding Clipper account. In order to alleviate this problem, Clipper allows riders to go as low as -$11.25 on the card before funds need to be added. Mobile wallets On April 15, 2021, the Clipper mobile app for iOS was released, and Clipper became available in Apple Wallet, joining other transit cards such as Suica, Pasmo, and TAP. Supported devices include iPhone 8 or later and Apple Watch Series 3 or later. Customers can create new virtual Clipper cards or transfer their existing plastic Clipper cards to Apple Wallet by using their iPhone's built-in NFC reader. On May 19, 2021, the Clipper mobile app was released for Android, and Clipper became available in Google Pay. Phones must have an NFC chip and be running Android 5.0 (Lollipop) or later to be used for mobile payment. Physical Clipper cards transferred to mobile wallets can no longer be reloaded or used to pay for fares, but will continue to work as keys to unlock Bay Wheels bikes and BikeLink bike lockers (see "" above). TransLink cards cannot be directly transferred to mobile wallets, as they cannot be read by the NFC reader inside a mobile phone. Clipper cards with a San Francisco State University Gator Pass or VTA SmartPass also cannot be transferred to mobile wallets.
