The touchless handshake is able to be performed by sending an ultrasonic signal from one device to another (or to multiple devices) which triggers the device to vibrate to simulate a handshake. Additionally, mobile devices are able to be used to send and/or display a wave. ## Claims ### Claim 1 A method comprising: triggering, with a first device, a touchless handshake; sending a wireless signal from the first device to the second device; receiving, with a second device, the touchless handshake; and acquiring a code displayed on the second device before sending the wireless signal by the first device. ### Claim 2 (depends on 1) The method of claim 1 wherein receiving the touchless handshake includes triggering a vibration mechanism of the second device. ### Claim 3 (depends on 2) The method of claim 2 wherein the first device and the second device vibrate simultaneously. ### Claim 4 (depends on 1) The method of claim 1 wherein the wireless signal comprises an ultrasonic signal. ### Claim 5 (depends on 1) The method of claim 1 further comprising performing machine learning to learn triggering the touchless handshake. ### Claim 6 (depends on 1) The method of claim 1 further comprising receiving, with at least one or more additional devices, the touchless handshake. ### Claim 7 (depends on 1) The method of claim 1 further comprising sharing contact information during the touchless handshake. ### Claim 8 (depends on 1) The method of claim 1 further comprising implementing a privacy policy to prevent sharing personal information. ### Claim 9 A device comprising: a non-transitory memory for storing an application, the application for: triggering a touchless handshake; sending a wireless signal to a second device; receiving a confirmation of the touchless handshake; and acquiring a code displayed on the second device before sending the wireless signal by the device; and a processor coupled to the memory, the processor configured for processing the application. ### Claim 10 (depends on 9) The device of claim 9 wherein the application is further configured for triggering a vibration mechanism in the device. ### Claim 11 (depends on 10) The device of claim 10 wherein the device and the second device vibrate simultaneously. ### Claim 12 (depends on 9) The device of claim 9 wherein the wireless signal comprises an ultrasonic signal. ### Claim 13 (depends on 9) The device of claim 9 wherein the application is further configured for performing machine learning to learn triggering the touchless handshake. ### Claim 14 (depends on 9) The device of claim 9 wherein the application is further configured for sending the touchless handshake to at least one or more additional devices. ### Claim 15 (depends on 9) The device of claim 9 wherein the application is further configured for sharing contact information during the touchless handshake. ### Claim 16 (depends on 9) The device of claim 9 wherein the application is further configured for implementing a privacy policy to prevent sharing personal information. ### Claim 17 A system comprising: a first device configured for: triggering a touchless handshake; sending a wireless signal; and a second device configured for: receiving the touchless handshake; and acquiring a code displayed on the second device before sending the wireless signal from the first device. ### Claim 18 (depends on 17) The system of claim 17 wherein receiving the touchless handshake includes triggering a vibration mechanism of the second device. ### Claim 19 (depends on 18) The system of claim 18 wherein the first device and the second device vibrate simultaneously. ### Claim 20 (depends on 17) The system of claim 17 wherein the wireless signal comprises an ultrasonic signal. ### Claim 21 (depends on 17) The system of claim 17 wherein the first device is further configured for performing machine learning to learn triggering the touchless handshake. ### Claim 22 (depends on 17) The system of claim 17 wherein the first device is further configured for sending the touchless handshake to at least one or more additional devices. ### Claim 23 (depends on 17) The system of claim 17 wherein the first device is further configured for sharing contact information during the touchless handshake. ### Claim 24 (depends on 17) The system of claim 17 wherein the first device is further configured for implementing a privacy policy to prevent sharing personal information.
