Ultra-wideband-enabled devices and systems

A method of operating an ultra-wideband-enabled payment acceptance system comprising:

• an ultra-wideband (UWB) anchor and a terminal device communicably coupled to the UWB anchor, the method comprising:
• transmitting, by the UWB anchor, a first pulse to UWB-enabled devices;
• receiving, by the UWB anchor, a second pulse from a particular UWB-enabled device;
• determining, by the UWB anchor, an approach angle of the particular UWB-enabled device and a distance between the UWB anchor and the particular UWB-enabled device;
• determining, by the UWB anchor, an intent to perform a payment transaction from the particular UWB-enabled device based on the approach angle and the distance between the UWB anchor and the particular UWB-enabled device;
• in response to determining the intent to perform the payment transaction from the particular UWB-enabled device, establishing, by the UWB anchor, a secure UWB communication channel with the particular UWB-enabled device;
• communicating, by the terminal device via the UWB anchor, transaction related information to the particular UWB-enabled device over the secure UWB communication channel;
• and
• receiving, by the terminal device via the UWB anchor, a transaction payload from the particular UWB-enabled device over the secure UWB communication channel based on authentication and consent processes carried out at the particular UWB-enabled device.
