    Abstract: Certain embodiments herein relate to determining a type of input device from which user input is received. Input devices, such as keyboards, scanners, card readers, other keypad devices, etc., may send information to a computing device. The information may include one or more characters or signals, each of which may be received by the computing device after a delay. Such a delay may be analyzed to determine a source or type of user input device. A threshold time may be established such that an identification and number of characters received before the threshold time is reached may be used to determine the source or type of an input device. In example embodiments, a distinction between a bar code scanner and a keyboard, among other types of input devices used in a product shipping application, may be determined.
