To spend your Ucoins, find a merchant participating in the project. You can easily find Ucoins on the map in your wallet. Once you have found a merchant you want to go to, use the map in the app to find your way to their business. When you pay for your order, let the business owner know that you want to pay with Ucoins. The business owner will then provide you with a QR code that you can scan using the "Pay" button in your app. Once you have scanned the merchant's QR code, confirm the payment on your smartphone and the transaction is done!
