I read this article today about how Nordstrom was using customers’ cell phone MACs to track them around their stores without their knowledge to get information on what parts of the store they go to. This technology can easily be put into Building Information Systems (BIM) which is part of a future Smart City development project. The article brings up what is the key point to future adoption of these technologies, citizen/consumer data privacy. Nordstorm was doing it without customers’ knowledge, they were forced to stop because of it after it was made public. Smart City concepts need to have near 100% transparent and closely watched/audited privacy policies. If that is put in place as the public/private Smart City developments are developed it will raise public approval.
This only works for United States and western countries. Since Smart Cities can be developed worldwide, other countries do not have the same privacy freedom expectations the United States has.
