Though there's no free trial for QR Batch, you can get a free sample QR Code.
Go to QR Batch and sign-up
Select the type of QR Code batch you want to create
Upload the data file and review the columns
Next, you'll see three QR code design options: standard black-and-white, custom with logo, and custom with background
You can add design to your batch of QR Codes and proceed to specify QR Code format and size
Once you submit these values, the app will ask you for a final confirmation
Here you'll be able to see the preview for one of the QR Codes. You can scan and test it.
If the QR Code works fine for you, you can go ahead to make payment and download the entire batch.
