The best thing about this is that it works with all devices, not just Android or iOS. It's easy to use as well - I like how they have made sure there are no unnecessary features for those who don't need them. It does take some time getting used to because of its complexity but once you get the hang of it you'll love it! We're solving problems by allowing our customers to pay in-store using their smartphone so we needed something which was secure and could work across multiple platforms. This has solved both issues perfectly.
