Pre-staging technology for self-service kiosks

A system for improving transaction processing efficiency of a point-of-sale (“POS”) terminal, the system comprising a smart card having a thickness not greater than 0.8 millimeters (“mm”) and a surface area not greater than 86 mm×54 mm and comprising:

• a wireless communication interface;
• a microprocessor;
• a user input system in electronic communication with the microprocessor, the user input system comprising:
• a keypad;
• an input controller that captures data entered using the keypad at a first location;
• a voice controller that generates an audio message confirming the data captured by the input controller;
• and an encryption controller that encrypts the data captured by the input controller;
• and
• executable instructions stored in a non-transitory memory, that when run by the microprocessor:
• formulates transaction instructions for the POS terminal based on the data captured by the input controller;
• configures the wireless interface to detect that the smart card is at a second location and within a wireless communication range of the POS terminal;
• when the smart card is at the second location and within the wireless communication range, initiates a secure communication channel with the POS terminal and selfauthenticates the smart card to the POS terminal;
• and
• transfers the transaction instructions to the POS terminal and autonomously triggers execution of a purchase transaction at the POS terminal, thereby improving the transaction processing efficiency of the POS terminal;
• wherein the executable instructions stored in the non-transitory memory, when run by the microprocessor:
• transfer the transaction instructions to the POS terminal over the secure communication channel;
• and
• only autonomously trigger execution of the purchase transaction after establishing contact-based communication with the POS terminal.
