UWB access rights update

A method of updating access rights between a physical access control terminal and a mobile device, the physical access control terminal comprising an electronic circuit and an ultra-wideband transceiver connected to the electronic circuit, wherein the method comprises:

• transmitting, by the electronic circuit via the ultra-wideband transceiver, a request message to the mobile device;
• receiving, by the electronic circuit via the ultra-wideband transceiver, a response message from the mobile device;
• determining, in the electronic circuit, using the response message, a distance of the mobile device from the physical access control terminal, wherein the distance is from a physical location of the mobile device to a physical location of the physical access control terminal;
• determining, in the electronic circuit, if the mobile device is within a pre-determined geometric proximity range of the physical access control terminal based at least in part on the distance;
• and
• based on a determination that the mobile device is within the pre-determined geometric proximity range of the physical access control terminal, transmitting, from the electronic circuit to the mobile device one or more update messages configured to update access rights data in a data store of the mobile device, wherein the updated access rights data define user access rights for one or more access control points and grant a user of the mobile device access at certain access control points.

A computer program product comprising a non-transitory computer readable medium having stored thereon computer code configured to control a processor of a physical access control terminal comprising an ultra-wideband transceiver, such that the processor performs the steps of:

• transmitting, via the ultra-wideband transceiver, a request message to a mobile device;
• receiving, via the ultra-wideband transceiver, a response message from the mobile device;
• determining, using the response message, a distance of the mobile device from the physical access control terminal, wherein the distance is from a physical location of the mobile device to a physical location of the physical access control terminal;
• determining, if the mobile device is within a pre-determined geometric proximity range of the physical access control terminal based at least in part on the distance;
• and
• based on a determination that the mobile device is within the pre-determined geometric proximity range of the physical access control terminal, transmitting to the mobile device one or more update messages configured to update access rights data in a data store of the mobile device, wherein the updated access rights data define user access rights for one or more access control points and grant a user of the mobile device access at certain access control points.
