I first covered Radpad over a year ago. The site allows you to pay your rent with a credit or debit card (for a fee).
At the time the fee to use a credit card was 2.99%. Generally not worth it, although in a pinch it could make sense if you needed some quick credit card spend.
Now they’ve reduced the fee for using a MasterCard to 1.9%… and that can be useful for earning rewards.
