want to create location tracking system (on security guards)

[Shery]

i'm confused what technology should i use to develop it..

1- RFID technology is bit expensive at my project.

2- can't get any further help on GPS tracking system.

3-what if we use Bluetooth technology for this project? how we use it?

Bluetooth tags and GPS devices are more expensive than RFID tags.

 

What problem are you trying to solve?

Rfid based wands are the traditional way to track patroling officers. Some have started to use the phone's gps though.

Static guards in an establishment used to walk to fixed scanning points there and clock in by certain predetermined times to prove they were present as contracted.

Reader of RFID are way expensive as compare to other...

Around 2USD for a RFID reader module.

GPS in mobile phone is not very accurate. Its reading jumps few meters to dozen of meters. My Samsung Galaxy S5 has options to enable/disable GPS from satellite and/or "GPS" from cell towers. There is huge difference in quality of signal from satellites and cell towers. Which can be easily seen turning one or the other on/off and walking city with Google Maps for instance. In village with a few distant cell towers around situation can be different and GPS from satellites could show more accurate result.

 

I have written Android app reading GPS from device, putting data to database, writing CSV file row, and adding it to listview on the screen.

Then wait second, or specified amount of time, and repeat.

It's consuming battery as hell.

Walking with Google Maps turned on, and we can literally see how percentage of available power is decreasing, IIRC 1-2% per minute of usage, so whole battery lasted for 70-80 minutes of experiment.

GPS devices are more expensive than RFID tags.

But everybody have mobile phone with GPS these days. It's just a matter of writing software for existing device at hand.

 

BTW,

It's illegal to distribute and sell Android app which is monitoring activity of user without his/her knowledge and permission in the Google Play Store.

So unfortunately won't be able to release soft for f.e. monitoring wife/husband activity. At least not without making whole website and store.
