บัตรของขวัญ Bunnings

Bought a $200 Bunnings voucher using Doge and saved the pdf to my phone. Displayed the PDF on the phoneso the 2 barcodes were visible. Turned up brightness a bit and the lady at the checkout experimented resizing the barcode a few times and bingo - all good.. So about an hour after purchasing the e-card i was already walking out of bunnings with my purchase... Will be much easier if you can print the voucher - as if they can't scan it the checkout person will have to manually enter 2 codes, but it can still be done either way... i just didn't have a printer handy to print out the PDF.
