Establishment of a secure session between a card reader and a mobile device

A mobile device comprising:

• a processor;
• one or more non-transitory computer-readable media storing instructions fora functional software module which, when executed by the processor, cause the processor to perform operations comprising:
• sending, by the processor, security related information of the functional software module to a computer system via a network, the security related information generated by the processor to include information representative of at least one of:
• content of the functional software module, or content of a software environment of the functional software module;
• receiving, by the processor, a validation result of a validation process performed by the computer system based on the security related information of the functional software module;
• and
• establishing, by the processor, a secure communication session between the mobile device and a mobile card reader coupled to the mobile device based on the validation result of the validation process indicating that the security related information of the functional software module has been determined to be valid by the computer system.

A non-transitory computer-readable medium storing executable instructions of a functional software module that are executable by one or more processors of a mobile device to configure the one or more processors to perform operations comprising:

• sending security related information of the functional software module to a computer system via a network, the security related information generated by the processor to include information representative of at least one of:
• content of the functional software module, or content of a software environment of the functional software module;
• receiving a validation result of a validation process performed by the computer system based on the security related information of the functional software module;
• and
• establishing a secure communication session between the mobile device and a mobile card reader coupled to the mobile device based on the validation result of the validation process indicating that the security related information of the functional software module has been determined to be valid by the computer system.
