Tesco have announced that from today customers in Tesco’s Extra stores will have access to free wifi:
From Aberdeen to Bournemouth, customers shopping in any of Tesco’s Extra stores will now have free, unlimited access by signing up with their Clubcard number. Those who do not have a Clubcard are able to use the service for 15 minutes free every 24 hours.
The signing up with a Clubcard number is really interesting. Not only will Tesco be able to track what you buy at the till, but having worked out the technicalities of in-store navigation using the triangulation of wi-fi routers they could potentially be tracking where you go in-store … or am I just being too suspicious.
