thanks a lot

for those who have trouble understanding this

1. Passive Tracking (Wi-Fi & Bluetooth Beacons)

   Your phone constantly searches for nearby Wi-Fi and Bluetooth signals.

   Retailers place Wi-Fi routers or Bluetooth beacons in stores to detect these signals.

   Each device has a unique MAC address (though modern phones often randomize this to prevent persistent tracking).

   These devices log when and where a phone is detected, creating a record of customer movement.

2. What They Can Track:

   When a customer enters or exits the store

   How long they stay

   Which areas of the store they visit

   Repeat visits (if the MAC address isn’t randomized)

   Whether they've visited other locations (if the same system is deployed across multiple stores)
