Abstract
Embodiments of methods and a system for wireless transactions are disclosed. In an embodiment, the method includes performing multicast Ultra-Wideband (UWB) ranging, where the multicast UWB ranging includes calculating a distance between a first device and a second device, and calculating an angle of arrival (AoA) of the second device, determining, using the distance and the AoA, whether the second device is located in a transaction zone that is defined by the first device, exchanging wireless transaction information between the first device and the second device when the second device is located in the transaction zone, where the wireless transaction information includes a transaction request, and initiating a transaction upon the second device accepting the transaction request and upon confirming, using the distance and the AoA, that the second device is still located in the transaction zone, and the second device is oriented towards the first device.
