FAQ
Frequently asked questions
Do my customers need an app?
No. The card lands in Apple Wallet or Google Wallet, both pre-installed on practically every smartphone. Scan the QR, add the card, done.
Does it work with Apple and Google Wallet?
Yes, with both. Gainback detects the device automatically and delivers the right pass, you don't have to set anything up.
Do I need a new register or hardware?
No. Stamping happens via a QR code at the front desk or a scan with any smartphone.
What does it cost for my studio?
That depends on the size of your studio. You get a clear quote in your call, with no setup fee and cancellable monthly.
Does it work across multiple locations?
Yes. One card is valid in every location, managed from a central dashboard, from the Growth plan with two locations, unlimited on Pro.
How many stamps should my card have?
Eight to ten works well: close enough to motivate, and enough visits for the reward to pay off. Tip: give the first stamp right when the card is added, started cards get filled far more often.
Can I switch from paper cards without losing my existing balances?
Yes. On the first scan you simply carry over the existing paper stamps as a starting balance on the digital card, no one starts from zero.
