A point-of-sale terminal comprises a processor, memory operatively coupled to the processor, a display screen operatively coupled to the processor and configured to display transaction information and a reader operatively coupled to the processor and configured to read a first two-dimensional encoded image pattern comprising payment information and personal security information necessary to complete a transaction. The processor is configured to decipher the first two-dimensional encoded image pattern to obtain the payment information and personal security information and complete the transaction based on this information. The personal security information comprises at least one of GPS information, time and date information, handheld device information and PIN information. The display may be configured to display a second two dimensional encoded image pattern generated by the processor that comprises transaction information readable by a handheld device that generates the first two-dimensional encoded image in response to the second two dimensional encoded image.
