Publication number: 20200327766Abstract: Examples of the present disclosure describe systems and methods relating to remote vending techniques. In an example, a vending device stocks one or more products to dispense to a user. A user computing device is used to communicate with a vending platform. The vending platform causes the vending device to dispense a product to the user. Since the user interacts with the vending platform and, in some instances, confirms his or her proximity to the vending device, the vending platform is able to gather and validate user information relating to the user and/or the user device. For example, the vending platform may collect a phone number, an email address, a device type, and/or a user location. Thus, such information gathered by the vending platform is usable to contact the user in the future, identify leads, and/or determine whether the vending platform assisted in converting a lead into a customer, etc.Type: ApplicationFiled: April 13, 2020Publication date: October 15, 2020Applicant: Space Station LimitedInventors: Boyd Ethan Wilkinson, William Troy Widgery, Sergii Skorostetskyi
