In order for you to use a Voucher during a sale you will need to scan it into the transaction as if it was an item. To do that you will need to create a barcode of the voucher number.
This is the voucher number which can be found under REPORTS->EXPORTS->LOYALTY VOUCHER PROGRAM
Copy the number in yellow above and paste it into this barcode generator. Then print out the barcode on your receipt printer or any printer so that you can scan it with your barcode reader.
