The setup for Transit Mode / Express Mode / Tap to ride without opening wallet varies by platform.
Step 1: Add a debit or credit card to your Apple, Google, or Samsung Wallet
Step 2: In Settings, enable “Express Mode” (iOS) or “Tap to ride without opening Wallet” (Android)
Step 3: Check before you travel. Does the public transport system in your city support regular contactless payments (authenticate phone first) or Express Transit Mode (fastest, just tap phone). Check the city list.
