In our project, there are over 200 dummy users who are not very capable of using mobile technologies or computers comfortly.
The project is essentially a MRP & Production Planning solution with machines connected to the server.
In the original idea, we thought it'd be good to have mobile tablets mounted at every machine, and give all of the users an RFID tag (a card really) to make them read by the tablet to authenticate the user.
But we've noticed that there are not too many tablets which supports NFC or RFID.
So, right now we're looking for an alternative solution.
Can anyone suggest any other technology that we can search through ?
