This Walmart store uses Mobile Location Analytics (MLA) technology to understand the traffic patterns of people during their visit. By learning and using insights, such as how long customers stand in line and how they generally move around an area, this facility can enhance operational efficiency and improve user experience.

Most MLA technologies operate by detecting your device’s WiFi MAC address or Bluetooth address – a 12 digit string of letters and numbers assigned to your device by its manufacturers. You can enter your MAC address at this site to opt out of the use of your MAC address for these programs by Walmart. Enter both your WiFi and Bluetooth MAC addresses to ensure the opt-out is effective across all participating Walmart stores. Opt outs are processed and take effect on a daily basis. Turning off your device’s WiFi or Bluetooth will also prevent your MAC address from being detected.

Your MAC address will be retained for the duration of Walmart’s use of MLA technology and will be used only for the purpose of maintaining the device’s opt-out status.

Devices running Apple iOS 8 automatically generate random WiFi MAC addresses, instead of broadcasting a consistent one (except when users have joined a particular network or certain other times). As a result, for iOS 8 users, tracking is limited in those circumstances and the WiFi opt-out is limited.

How to find your Wi-Fi or Bluetooth address

A Wi-Fi or Bluetooth address is a unique 12 digit identifier that is also commonly called a MAC (Media Access Control) address or network name:

e.g. 01-23-45-67-89-ab or 01:23:45:67:89:ab

A MAC address is unique to your device and is stored in your device's networking hardware by the device manufacturer. It allows your device to connect to Wi-Fi, Bluetooth or other wireless networks.
