For those who are interested in an easy and secure solution for working with Stipe that is similar to Stripe checkout, but looks much better and works with multiple products and quantities. There is a new solution from Stripe Collect, called Collect WebForms. It is brand new and they are developing new features for it all the time and is tightly integrated with Stripe for working with subscriptions. There is a related cost of 1% and no monthly minimums. I like the speed to create a solution and they claim it works with any currency. Here is the link: https://collectforstripe.com/features/web-forms
We use the collect card reader and have been very happy with it and now with the Web solution, it seems like another good option. Let me know what you think? They also have an API that I have not played with yet.
