By using Swish QR codes, you make it even easier for your customer to pay to you with Swish. Which payment details you choose for your codes should depend on when and where you’re planning on using them. Sometimes it might be sufficient with just your Swish number, but in other situations you can add an amount and a message. You can also choose if the customer should be able to adjust the amount and/or the message. If you want to make sure that the payment includes the correct amount and message you just lock those fields to prevent them from being adjusted.
