Abstract
One embodiment provides a method that performs the steps of collecting network signal information from a sensor of a mobile device located in a designated vendor area. The network signal information is produced by a fixed transmitting device and has a corresponding network time stamp. The mobile device located in the designated vendor area receives a payment notification from a vendor; extracting from the payment notification, time stamp information and a name of the vendor sending the payment notification; and matching the time stamp information with the corresponding network time stamp and automatically updating a labeled localization database. The labeled localization database comprises previously mapped localization information corresponding to multiple spatial zones of the designated vendor area and the updating comprises linking the name of the vendor sending the payment notification with a physical location of the fixed transmitting device. Other aspects are described and claimed.
