Mifare Ultralight Ev1
Hi everybody,
I recently finished working on a new app. It basically allows you to handle Mifare Ultralight tags.
Mifare Ultralight tags are inexpensive tags that are being used world-wide for a number of different tasks: public transportation, events, authentications and so on. The best thing about it (from my wicked point of view) is that it is not encrypted, which means that you can easily read/write those tags (as long as the contents of the tag can be overwritten).
As far as I know, there are some apps available for reading/writing tags, but most of them are either expensive or only allow you to write one word (32 bit) at a time, resulting in a long and boring process when you need to create a tag from scratch (i.e. writing 16 words on it), or editing multiple words.
This is why I came up with UltraManager. If you are in possess of Mifare Ultralight tags and you would like to find out more about their contents, this is the app you need.
At first I thought of only selling the app; but since the number of systems using Mifare Ultralight tags is getting higher as the time goes by, I wanted to allow as many people as possible to put their hands on those systems.
This is why I developed both a Lite and a Pro version. If you are only interested in doing some basic operations with your Mifare Ultralight tag, the Lite version will do just fine. There are no ads, and you will be able to read, edit and write tags.
If you find the app useful, or you need other features, there is a Pro version available as well: many other options are available for this version. The price for the Pro version is € 0.99 ($ 1.36).
The permissions required by both the Lite and the Pro apps are:
Network communication - control Near Field Communication
UltraManager Lite - Google Play
UltraManager Pro - Google Play
Any comment, suggestion and feedback is welcomed.
Thank you all,
