Big Brother Is Watching

Some large retailers are also tracking your journey through their stores.
Use a credit or debit card and they have your personal info and preferences.
You are then the 'target' of 'targeted advertising'

What can you do so that doesn't happen
Turn off your smart phone before entering the store, or leave it in the car.
Turning off your GPS feature does not defeat this tracking.

What's next?
After the advertisers 'prove' the technology, the next may be government.
