Sign in on a staff device

Log in on a shared or private phone.

Staff must sign in with their own stmpr account in the scanner app. On a shared counter phone, sign out at end of shift.

After login they pick a store if they belong to more than one.

Role controls what they can do: stamp, redeem, or limited view only.

Why use this?

Signed-in staff appear in the activity log so work is traceable.

Invited accounts are safer than sharing the owner password.

Biometric unlock (Face ID, fingerprint) speeds daily use.
