1. A system comprising:

  • a security device unit comprising;

    a housing;

    means for communicating wirelessly using technology to limit a separable distance for operation;

    a processor for;

    verifying a validity of a request for a transaction;

    issuing an alert of receiving a valid request;

    acknowledging a user'"'"'s indication of an acceptance of the request;

    generating a first one-time identifier, upon the acknowledgment, the first one-time identifier at least comprising a security device identification, a transaction number, a date and a time;

    storing the request and transaction number to form an audit trail;

    incrementing the transaction number for each subsequent transaction;

    instructing said communicating means to communicate the first one-time identifier;

    verifying a validity of a second one-time identifier for a processed transaction; and

    instructing said communicating means to communicate an acceptance of the transaction upon the second one-time identifier being validated;

    an indicator for receiving the alert from said processor to alert the user; and

    a sensor for receiving the user'"'"'s indication of an acceptance and transmitting the indication to said processor;

    an application programmable device executing an application, said application programmable device for;

    communicating with said communicating means;

    communicating the request for the transaction to said communicating means;

    receiving the first one-time identifier from said communicating means;

    verifying a validity of the security device identification;

    sending the first one-time identifier and transaction for processing, upon verification of the validity;

    receiving a second one-time identifier indicating the transaction processed; and

    communicating the second one-time identifier to said security device; and

    an application controlling institute for;

    communicating with said application programmable device;

    supplying the application to said application programmable device;

    receiving the first one-time identifier and transaction for processing;

    verifying a validity of the first one-time identifier;

    processing the transaction using the security device identification to determine account information, upon verification of the validity;

    generating the second one-time identifier; and

    sending the second one-time identifier to said application programmable device, wherein said security device, application programmable device, and application controlling institute securely process the transaction.
