Abstract: An ultra-wideband (UWB)-enabled payment acceptance system can include a UWB anchor and a terminal device. The UWB anchor identifies UWB-enabled devices within a vicinity; and in response to receiving an indication of an intent to perform a payment transaction from a particular UWB-enabled device, the UWB anchor establishes a secure communication channel with the particular UWB-enabled device. The terminal device, via the UWB anchor, communicates transaction related information over the secure communication channel to the particular UWB-enabled device and receives a transaction payload from the particular UWB-enabled device over the secure communication channel. A UWB-enabled device includes a processor, storage, a battery, and a UWB chip. Instructions can be stored in the storage of the UWB-enabled device that when executed by the processor direct the UWB-enabled device to perform various processes supporting frictionless transactions, such as with respect to the UWB-enabled payment acceptance system.
