Buying this voucher through Traveloka does not have a bar code or QR code, which is very annoying. When I went to the JR pass exchange at the station, they gave me a piece of paper, only accepting vouchers with bar codes or QR codes, but only voucher numbers were not accepted, I was so scared. Luckily, the staff was enthusiastic in helping me. They had to ask me if I had time to wait because this takes a long time. I stood there for 45-50 minutes to finish. So I hope Traveloka will issue a bar code or QR code to help customers avoid suffering.
