How can I print a gift card with a unique 2D barcode at home?

[Lucas94]

I´m searching for a possability to let my customers buy a gift card print it at home. The Problem is: We are not using Shopify POS in our restaurant and we need a possability to print a 2d barcode on the gift card. So far no problem but shopify always adds "shopify-giftcard-id-" to all barcodes printed on a gift card. Is there any opportunity to get a barcode with just the gift card code?

Thanks a lot for your time!
