There are a lot of good payment services out there. PayHere and TillyPay are two of them.
PayRequest is another great one. It is especially interesting for me because it supports Ideal which is crucial for a Dutch audience.
What I like as well is that they keep on developing new stuff.
I like the dynamic creation of QR codes for example.
So with templates in Glide you can dynamically make new QR codes depending on the price or sum in your app.
In this case I can make a template where PRODUCT is what the spreadsheet says people buy (One Stop Shop) and PRICE is what the spreadsheet says people have to pay (20 euro in this case).
I say: handy!
