OISY Pay

OISY Pay lets you complete real-world and online payments using Open CryptoPay. It’s designed for simple checkout flows where you either scan a QR code or paste a payment link, then send the exact amount from the asset and network you choose.

Where you can use it

OISY Pay works with all Open CryptoPay-enabled merchants, including:

• SPAR Switzerland

• Shopware stores

• WooCommerce stores

For more details see here: https://opencryptopay.io/ecosystem.html

How it works

Merchants generate a payment request (QR code or URL) via Open CryptoPay.

You approve camera access (for QR scans) or paste a link manually, choose what you want to pay with, then confirm the transaction in OISY.

Supported assets

When paying, you can select from:

• ICP

• ckBTC

• VCHF

• VEUR

• BTC

• WBTC

• ETH

• USDC

• USDT

• dEURO

• ZCHF (Frankencoin)

• DAI

• BNB

• SOL

Pay flow

1. Open OISY

2. Tap the Universal Scanner icon (top-right)

3. Choose how to enter the payment request:

   • Scan QR code (enable camera permission when prompted)

   • Paste URL (manual link input)

4. Select the asset and chain you want to pay with

5. Review recipient details (tap the arrow next to Recipient to expand)

6. Tap Pay

7. After confirmation, you’ll see a Payment Confirmed screen with the merchant name and amount

Recipient details you can review

Before you pay, you can expand the recipient section to view:

• Name

• Address

• Country

• Phone number

• Email address

• Website

Payment confirmation

Once the transaction is successful, OISY displays a confirmation screen showing:

• The merchant (example: Paid at SPAR)

• The amount paid (example shown in USDC)

• “Powered by Open CryptoPay” branding for clarity on the payment rail

Notes

• If scanning is blocked, check your device camera permissions for OISY.

• If you received a link instead of a QR code, you can paste the URL directly to start the same flow.
