I like how easy it is for me as an end user, or even developer who wants to create their own apps with this API's. It has been very helpful in creating applications where data can be sent from one device (mobile phone) via WiFi network connection to another mobile app/device when using NFC technology. The only down side of this product would probably be its price tag but overall great! So far so good nothing at all dislike about this product yet because there are no problems being experienced right now. If i was asked what could have made my life easier while developing my application, then maybe adding more options such as multiple connections per single MOKANIX card? That way we will not need to download each time new files which contain different functions. This helps us save storage space since most devices do hold limited amount of memory capacity.
