deals site qr code generator

We are selling deals and I want to create a qr code and pass the voucher code for each dynamically created voucher.

I have the code as a shortcode [vou_code] – is it possible to do something like this?

basically I want the end user (merchant) to use an app to scan a code and then open the page on our site for code verification with the code already in the check voucher code box

here is the page they would open in their phone after scanning –

I want the code to be already in the box so all they need to do is click CHECK IT and then if it is valid click the REDEEM button
