Systems and methods for electronic receipt transfer using ultrawideband radio technology

A payment terminal device, comprising:

• a memory comprising a payment terminal computer program;
• an ultra-wideband (UWB) radio comprising a plurality of antennas;
• a processor configured to execute the payment terminal computer program;
• wherein the payment terminal computer program is configured to:
• cause a wake-up signal to be transmitted, wherein the wake-up signal causes customer electronic device UWB radios on one or more customer electronic devices to be activated;
• cause the UWB radio to transmit a range request signal from a first antenna;
• receive from each of one or more customer electronic devices, each customer electronic device comprising a customer electronic device UWB radio, a pair of replies to the range request signal, the pair of replies comprising a first reply signal received at the first antenna and a second reply signal received at a second antenna;
• determine a distance between the UWB radio and each customer electronic devices based on a time of flight for the range request signal and the pair of reply signals;
• select one of the one or more customer electronic devices that is within a predetermined distance;
• communicate a request for approval for an electronic receipt transfer to the selected customer electronic device using the UWB radio;
• receive an approval message for the electronic receipt transfer from the selected customer electronic device without customer contact information for customer using the UWB radio;
• and
• communicate an electronic receipt for a transaction to the selected customer electronic device.
