Dear Olly
Twint Payment is used in Switzerland for about 70% as a means of payment.
And many of my customers want me to connect Twint as a means of payment in the pizza shop.
There is a lot of competition in this area and I don’t want to lose customers because they find WP Shop very good and I have about 100 customers who are all programmed with WP Shop Plugin. That’s why I have a “WPPizza All Access Pass” license!
I am aware that Saferpay Gateway also supports Twint!
However, Saferpay requires very high annual fixed costs, plus a percentage of orders.
That’s why many don’t want to sign a contract with Saferpay.
Twin gives business customers the option of connecting an online shop via a plugin, payment service or sticker code.
In the twint list there is already WordPress WooCommerce and WordPress E-Commerce.
The easiest way is if you can program a Twint plugin for us, just like PayPal etc..
I’m willing to pay you for your work.

I hope you can do it.
Best regards
umut
