Multi-location chains

Who each is designed for

Stampaki — Local businesses and agencies, especially in Greece, that want branded Wallet cards in Greek and English without a monthly platform subscription.

Boomerangme — Businesses, agencies and franchises internationally that want a wide set of card types, automation and integrations under a monthly plan.
