7stamp puts loyalty cards into Apple Wallet and Google Wallet. No app for the customer to install, no staff training, no POS integration. Customers join in about 15 seconds by scanning a QR code. It is on Dealify at 80% off, and I bought it.
The thing I liked before the price is the honesty. The FAQ says out loud that lifetime means capacity, not unlimited, which is the sentence most of these listings avoid. When a vendor tells you where the ceiling is before you pay, the rest of the page gets easier to trust.
The entry tier is not the product. At $99 you get three business profiles and 7,500 stamps a month, which is one shop and no leverage. The real tier is the white label one: your own domain, your own branding, and ten client businesses you can sell at your own price.
That is why I bought it. I already have clients I look after, and this is something I can hand them as part of what they already pay for. It costs me nothing extra per client and it gives them a reason to stay.
My verdict: 4 stars, bought. If you run one shop, the cheap tier is not worth it. If you have clients, the white label tier is the whole point.
