for push-based lba, users must opt-into the company's lba program; this would most likely be done via the seller's website or at the store. then users would be requested to provide their personal information, such as mobile phone number, first name, and other related information. after the data are all submitted, the company would send a text message requesting users to confirm the lba subscription. once these steps have been completed, the company can now use location-based technology to provide their customers with geographically based offers and incentives.
