Smart QR insert cards for online sellers
Turn every insert card into a loyal customer.
Put a Kartzo QR code in the box. Buyers scan it to register their product, watch setup videos and join your list. You get their email, honest feedback and a clear view of what to improve.
Works for Amazon, Etsy, Shopify, Walmart, eBay and your own store.
From the box to your brand in three steps.
No app to download. Buyers scan with their phone camera.
Build your card
Pick your products, add a setup video or guide, and choose a thank-you offer if you want one. Kartzo makes the QR code and a print-ready card.
Buyers scan
They land on your branded page, register their product, get help, and share how it's going. Every buyer sees the same steps.
