receiving, by the payment terminal computer program and one or more customer electronic devices, a pair of replies to the range request signal, each comprising a first reply signal received at the first antenna and a second reply signal received at a second antenna; determining, by the payment terminal computer program, a distance between the UWB radio and each customer electronic device based on a time of flight; selecting, by the payment terminal computer program, the customer electronic devices having the distance that is closest to the UWB radio; and communicating, by the payment terminal computer program, an electronic receipt for a transaction to the selected customer electronic device. ## Claims ### Claim 1 A method for electronic receipt transfer via ultra-wideband electronic radio technology, comprising: causing, by a payment terminal computer program executed by a payment terminal comprising a computer processor, 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 turned on or activated; causing, by the payment terminal computer program, an ultra-wideband (UWB) radio to transmit a range request signal from a first antenna; receiving, by the payment terminal computer program and from each of the one or more customer electronic devices comprising the customer electronic device UWB radios, 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; determining, by the payment terminal computer program, a distance between the UWB radio and each customer electronic device based on a time of flight for the range request signal and the pair of reply signals; selecting, by the payment terminal computer program, one of the one or more customer electronic devices that has the distance that is closest to the UWB radio; communicating, by the payment terminal computer program and using the UWB radio, a request for approval for an electronic receipt transfer to the selected customer electronic device; receiving, by the payment terminal computer program and using the UWB radio, an approval message for the electronic receipt transfer from the selected customer electronic device without customer contact information for customer; and communicating, by the payment terminal computer program and using the UWB radio or a RF radio, an electronic receipt for a transaction at the payment terminal to the selected customer electronic device. ### Claim 2 (depends on 1) The method of claim 1, further comprising: determining, by the payment terminal computer program, that the selected customer electronic device is within a predetermined distance of the payment terminal. ### Claim 3 (depends on 1) The method of claim 1, wherein the approval message comprises an identification of a communication channel for receiving the electronic receipt comprising one of UWB Bluetooth, WiFi, NFC. ### Claim 4 (depends on 1) The method of claim 1, wherein the approval message comprises an identification of a communication channel for receiving the electronic receipt comprising one of short messaging service (SMS) and email, and an address comprising one of a SMS address and an email address. ### Claim 5 (depends on 1) The method of claim 1, further comprising: determining, by the payment terminal computer program, a position of each of the one or more customer electronic devices using an angle of arrival for each first reply signal and second reply signal. ### Claim 6 (depends on 1) The method of claim 1, wherein the electronic receipt is communicated as an image file. ### Claim 7 A payment terminal device, comprising: a memory comprising a payment terminal computer program; and 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 the 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 a desired one of the one or more customer electronic devices based on the respective time of flight of the pair of replies; 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. ### Claim 8 (depends on 7) The payment terminal device of claim 7, wherein the payment terminal computer program determines that the selected customer electronic devices is within a predetermined distance of the payment terminal device. ### Claim 9 (depends on 7) The payment terminal device of claim 7, further comprising a Bluetooth, WiFi, or NFC radio, and the approval message comprises an identification of a communication channel for receiving the electronic receipt comprising one of UWB, Bluetooth, WiFi, and NFC. ### Claim 10 (depends on 7) The payment terminal device of claim 7, wherein the approval message comprises an identification of a communication channel for receiving the electronic receipt comprising one of short messaging service (SMS) and email, and an address comprising one of a SMS address and an email address. ### Claim 11 (depends on 7) The payment terminal device of claim 7, wherein the payment terminal computer program is further configured to determine a position of each of the one or more customer electronic devices using an angle of arrival for each first reply signal and second reply signal. ### Claim 12 (depends on 7) The payment terminal device of claim 7, wherein the electronic receipt is communicated as an image file.
