Systems and methods for tracking access to an area using ultra-wideband radio technology

A method for tracking entry to, presence in, and exit from an area using ultrawideband (UWB) radio technology, comprising:

• receiving, by a payment terminal computer program executed on a payment terminal and from an UWB radio, a first communication comprising first information for the payment terminal computer program to determine a first distance between a UWB radio-enabled mobile electronic device and the UWB radio;
• determining, by the payment terminal computer program, that the UWB radio-enabled mobile electronic device is at an entrance to the area based at least in part on the first distance;
• receiving, by the payment terminal computer program and from the UWB radio, a second communication comprising second information for the payment terminal computer program to determine a second distance between the UWB radio-enabled mobile electronic device and the UWB radio;
• determining, by the payment terminal computer program, that the UWB radio-enabled mobile electronic device is at an exit from the area based at least in part on the second distance;
• determining, by the payment terminal computer program, a fee based on the first communication and the second communication;
• receiving, by the payment terminal computer program and from the UWB radio, a third communication comprising third information for the payment terminal computer program to determine a third distance between the UWB radio-enabled mobile electronic device and the UWB radio;
• determining, by the payment terminal computer program, that the UWB radio-enabled mobile electronic device is in a sub-area of the area based at least in part on the third distance;
• adjusting, by the payment terminal computer program, the fee based on the determination;
• and
• controlling, by the payment terminal computer program, an access control device in response to receipt of the fee.
