Hi,
it’s possible to make the login process simpler.
Voucher can be used straight away without the ‘activation’ process. If your users type the voucher code into the username in the login box field, the voucher will be activated and the user will log in straight away.
So you should turn the voucher activation module and you can also modify the printed voucher code to have the instructions to type the voucher code into the username field and that’s it.
Furthermore if you have a voucher only location, you can even use a simple login form, where the system only asks for the username only (this is a setting in the control center).
Hope that helps.
