No problem. You have two options:
1. You can order a TAP card online for $2 at TAPtogo.net.
2. You can ride on Metro Bike Share without a TAP card: Download the Metro Bike Share app and log in to your Metro Bike Share account to access mobile bike check out. You can also walk up to a Metro Bike Share station and use your phone number at the kiosk to unlock a bike.
