Systems and methods for integrated, secure point-of-sale transactions

A system for processing transactions, comprising:

• a base station comprising:
• a processor;
• a Wi-Fi communication module;
• a plurality of payment modules configured to perform payment transactions;
• and
• a first Wi-Fi transportation authority application, which causes the processor to control the Wi-Fi communication module;
• a gateway server which transmits payment transaction requests from the plurality of payment modules and receives transaction data in response to the payment transaction requests;
• and
• at least one mobile device comprising:
• a processor;
• a point-of-sale (POS) module configured to perform POS operations;
• a Wi-Fi Communication module;
• and
• a second Wi-Fi transportation authority application which causes the processor to control the POS module and the Wi-Fi communications module;
• wherein the first Wi-Fi transportation authority application is configured to cause the processor of the base station to prevent the Wi-Fi communication module of the base station from communicating with the POS module unless the second Wi-Fi transportation authority application has been authenticated by the first Wi-Fi transportation authority application;
• and
• wherein the second Wi-Fi transportation authority application is configured to cause the processor of the at least one mobile device to prevent the POS module and the Wi-Fi communication module of the at least one mobile device from communicating with the Wi-Fi communication module of the base station unless the first Wi-Fi transportation authority application has been authenticated by the second Wi-Fi transportation authority application.
