Abstract
In some examples, a computer system receives, via a network and from a software module executable on a mobile device coupled to a card reader, security information that includes first security information associated with the card reader and second security information that is based on content of the software module and/or a software environment of the software module. The computer system determines validity of the first security information associated with the card reader based at least on information previously stored in the card reader and also accessible to the computer system. The computer system also determines the validity of the second security information. Based on determining the first and second security information are valid, the computer system sends, to the mobile device, an indication that the computer system has validated the security information, prompting the software module and the card reader to establish a secure communication session with each other.
