A method, comprising: receiving registration information, from a cloud computing system for a client device at a facility device (206, 504), wherein the facility device has access to a collection of entries associated with a plurality of client devices (408a to 408g), each entry including user verification information for an individual associated with the client device; receiving, at the facility device, a signal transmitted by the client device, the signal including a value associated with the client device; detecting, at the facility device, a trigger condition associated with a proximity of the client device relative to the facility device based on the signal transmitted by the client device; and in response to detecting the trigger condition and based on the signal received from the client device: identifying, at the facility device, an entry from the collection of entries corresponding to the client device; updating, at the facility device, a subset of entries to include the entry from the collection of entries corresponding to the client device and including user verification information for an individual associated with the client device; wherein the subset of entries corresponds to one or more client devices that has been registered with the cloud computing system and for which the triggering condition has been detected; and further comprising tuning a transmission power of an antenna on the facility device, wherein detecting the trigger condition comprises detecting that the client device is both within a predetermined proximity and in a predetermined direction relative to the facility device, and wherein the predetermined proximity is based on the tuned transmission power of the antenna. receiving registration information, from a cloud computing system for a client device at a facility device (206, 504), wherein the facility device has access to a collection of entries associated with a plurality of client devices (408a to 408g), each entry including user verification information for an individual associated with the client device; receiving, at the facility device, a signal transmitted by the client device, the signal including a value associated with the client device; detecting, at the facility device, a trigger condition associated with a proximity of the client device relative to the facility device based on the signal transmitted by the client device; and in response to detecting the trigger condition and based on the signal received from the client device: identifying, at the facility device, an entry from the collection of entries corresponding to the client device; updating, at the facility device, a subset of entries to include the entry from the collection of entries corresponding to the client device and including user verification information for an individual associated with the client device; wherein the subset of entries corresponds to one or more client devices that has been registered with the cloud computing system and for which the triggering condition has been detected; and further comprising tuning a transmission power of an antenna on the facility device, wherein detecting the trigger condition comprises detecting that the client device is both within a predetermined proximity and in a predetermined direction relative to the facility device, and wherein the predetermined proximity is based on the tuned transmission power of the antenna. identifying, at the facility device, an entry from the collection of entries corresponding to the client device; updating, at the facility device, a subset of entries to include the entry from the collection of entries corresponding to the client device and including user verification information for an individual associated with the client device; wherein the subset of entries corresponds to one or more client devices that has been registered with the cloud computing system and for which the triggering condition has been detected; and further comprising tuning a transmission power of an antenna on the facility device, wherein detecting the trigger condition comprises detecting that the client device is both within a predetermined proximity and in a predetermined direction relative to the facility device, and wherein the predetermined proximity is based on the tuned transmission power of the antenna.
