In first we need an android app which reads NFC-Chips.
The chips should store to a secured webbased database. If no connection to the server the chips have to save on the smartphone and try to send out in periods.
The chip is to find in the database of all active chips.
The active chips are declared in in futher columns. This 2. column and 3. column is read out and write in the display.
In example: You read a chip with S/N 123456789A then send to server, search for this S/N, and if found it give back the name (2. column) and Describtion (3. column)
Practices ideas are helpful.
In the database we need from the all readers following information
date/time of transfer
IMEI of reader or other unique of reader
date/time of reading chip
gps position, for realtime monitoring if gps is activated
