US11216811B2 Systems and methods of verifying installation of building automation devices
Methods and systems may be configured to verify proper installation of Internet Protocol (IP) connectable building automation devices by installers at remote sites. The installers may be a crowdsourced installers. A service provider may engage an installer to install one or more IP connectable building automation devices. To ensure verification that the one or more IP connectable building automation devices are installed properly, parameters or values based on data from installed IP connectable building automation devices may be provided to or determined by a blockchain network. The blockchain network may compare the parameters or values to thresholds and automatically provide an indication as to whether the parameters or values meet or exceed the thresholds (e.g., verification criteria).
US11216806B2 Systems and methods for providing card interactions
A method including receiving a first application user credential associated with a user profile; comparing, for a first match, the first application user credential with a stored second application user credential, wherein the stored second application user credential is associated with a user identity; and responsive to finding a first match, verifying the user identity by performing the following: communicating with a card using near field communication; receiving a public key of a key pair of the card and cardholder identification information of an account holder of the card; instructing the card to generate a digital signature; receiving the digital signature from the card; verifying the digital signature using the public key; and comparing, for a second match, at least a portion of the user identity with at least a portion of the cardholder identification information.
US11216803B2 Authentication token for wallet based transactions
Transaction address data is received at a point of interaction (POI) device, from a payment-enabled mobile device. The transaction address data includes first address data and second address data. The first address data identifies a wallet service provider that is associated with the payment-enabled mobile device. The second address data indicates an internet address for a server function present in the payment-enabled mobile device. The first address data is used to dispatch the second address data from the POI device to the wallet service provider.
