Do I need to build a mobile payment app?+
No. Your POS sends a payment request from its backend. The nashi app handles Tap to Pay on a compatible phone, so your checkout can stay on the web, a tablet or your own app.
Can my POS and phone be different devices?+
Yes. Run your POS on a laptop or tablet and send the payment to a connected phone running nashi. The amount and order reference arrive together, so there’s no need to type them in again.
How does my POS know a payment is complete?+
nashi sends the payment result to your integration through a webhook, so your POS can automatically update the matching order.
How do I get started?+
to connect your merchant account and get your API credentials. You’ll need a compatible phone with the nashi app and an approved merchant account to accept payments.
