Abstract
In one or more implementations, a computing device may receive information from a matrix code reader that scans multiple matrix codes, each displayed by one of multiple devices. The computing device may determine whether or not the devices are being fraudulently utilized, such as whether the devices are in the same location. Additionally, in some implementations, a computing device may receive a service request from a matrix code reader that includes an associated telephone number. The computing device may extract the number and may handle the service request based on the number. Moreover, in various implementations, a computing device may receive information from a matrix code reader that scans a displayed matrix code. The information may include an electronic signature that is included in the matrix code by the device. After receiving the information, the computing device may analyze the information to determine that the electronic signature is valid.
