Abstract: Systems and methods that facilitate authenticating a user making a payment using microelectromechanical systems (MEMs) devices (i.e., smart dust). The MEMs devices may have sensors that collect data and transfer it to a base station device. The MEMs devices can collect sensor data, including biometric data and/or capture images of the person. The MEMs can also collect sensor data such as audio data, optical data, temperature data, pressure data, and motion data and compare it to data associated with a user profile to determine that the person making the payment is the same person associated with the user profile. Once the person's identity has been confirmed, and thus authenticated, the payment request can be confirmed and payment made, via either the mobile device or credit card.

Abstract: A first electronic computing device receives a first message from a first user at a second electronic computing device to establish a communication. A determination is made as to whether a device identifier for the second electronic computing device is included in a profile of permissible electronic computing devices. When a determination is made that the device identifier is included in the profile, a communication session is established with the second electronic computing device. A second message is received from a second user at a third electronic computing device. A determination is made as to whether the second user is the same as a first user. When a device identifier for the third electronic computing device is included in the profile and the second user is the same as the first user, the communication session is transferred from the second electronic computing device to the third electronic computing device.
