Select a car and create a QR trade card. The car data is stored inside the QR itself, so Cloudflare is not required.
Scan their QR or paste their TapCar transfer code. This works without a Cloudflare account.
Move a copy of the selected car directly to another local TapCar account on this device.
Challenge another signed-in player by username. The server compares the selected cars across power, speed, handling and collector score.
Your local account now includes its own garage, QR trading, local multiplayer, backup/export, restore/import, and separate progress. Cloudflare is optional.
Save your local account to a backup file, then restore it on another device. This is the local alternative to cloud sync.
Only needed if you want internet multiplayer between distant devices and automatic server backup.
