About this app

We have added lots of new features to the G-tos app.
Now the app can write data on writable NFC tags.


The Gtos / G-tos app can scan/read NFC tags, Qr codes, and Barcodes. The app can also write NFC data on to NFC tags.

We designed the app to provide you with a much better presentation of scanned data and also to give you the right options related to the data you scanned.

We are constantly working on perfecting the app, so please if you find any issues let us know.
