1 - What's the point in trying to armchair-design payment processing systems? You obviously don't work in the field.
2 - You DO NOT want secure data stored as a cookie to be sent to the domain with *every single request* (this is how cookies work).. This just makes it that much easier to acquire during redirection attacks on the browser, and is totally not needed.
3 - It wouldn't help anyway, because it would mean that every single request coming from your browser to the domain would contain the sensitive data, so it would be even less controlled, even on the server side.
You claim people are shooting down ideas without offering solutions, but they *are* pointing out solutions. For example I said using Stripe could achieve this, and it would be more secure than the current situation (Stripe's whole business is secure transactions and they have a lot of smart people who've been successful at other online payment organizations). You're just objecting because they don't agree this would be a win.
*sigh* I do work in the field, not game design but other IT, and it has been awhile since I learned web design but I thought a cookie could be used to just talk to the website when you go there, so like when I go to buy something it could pull that info when I go to check out. But regardless it was a spitball idea, to offer something constructive. You did not, however, say why having the GoG Galaxy save it would not work...nor did you come up with anything that might make GoG offer faster checkout without a 3rd party.
And sadly, while you have a good point, I'd sooner keep my credit card handy, than to go though Stipe, but most potential users will not use it nor go digging for their card. I do not object because nobody agrees, but because everyone is so firm on the idea that the GoG gods that they are can't possibly be seen as not user friendly to a large group of people. This is not really about me, as I said I have my solution to buy games here.
What is the point of arm-chair design? Maybe we could come up with something useful? Make GoG a better place? Make it bigger? Make devs fight to get their games on here like the used to when steam was halfway respectable? It may be point less, but I tried. Maybe all the GoG fans are too into the way things run here, I know the steam fanbase is horrible now days...I would hope here maybe people could kick around some ideas, think outside the box and find a way to get more people involved. Even if you never use it yourself, there is nothing wrong with more sales and games here, i'd probably use it though if it could be made safe, and many who would not buy games here now might start.
@onarliog, you replied while posting
I was seeing it as an option, like when you go to check out, it would say, "Would you like us to store you credit card information on your computer for easy check out next time" and you can tick the check if you want to...or not. It would not have to be encrypted, I'd think they could say if it was or not.
