Attention to detail: Stripe’s attention to detail is great. Their new button automatically detects the credit card brand you’re using. Previously input data is still there when you navigate away from the checkout. 

Payments: @Uber’s simple way to take payments. Users can hold up their card, take an image and confirm the data output.

Payments: Themeforest (@envatowebdesign) uses prepaid credits as the main payment method on their site. They show the price when paid with prepaid credits. The microcopy says “Add $2 if you are not using prepaid credits”.

Payments: Tumblr (@tumblr) makes it especially easy to pay. Instead of a ugly huge payment processing form you get a small overlay with the necessary few input fields. You can still see exactly what you’re spending the money for.
