The display panel is typically activated when user uses the card. This can occur when the card is swiped, and/or is powered up via an integrated energy panel (e.g., by an external light source). Alternatively, the card can be powered by RFID coupling, smart IC contact, battery, etc. Upon powering up, displayed information is used to: identify the user; and/or show private information to user only. Along these lines, displayed information can remain in card memory and/or on the display until next transaction, or it can be deleted after a programmed duration. ## Claims ### Claim 1 A card for dynamically displaying information pursuant to user authentication, comprising: a dynamic display for displaying information; an integrated circuit (IC) for controlling the dynamic display and for accessing a memory medium on the card, the memory medium storing the information; and an energy component, wherein the card is powered by alignment of the energy component with a light source of a point of sale terminal; a biometric reader; and an imager; wherein the user authentication is performed by: receiving a source verification code (SVC) via the imager, the SVC being generated based on the card information; generating a card validation code (CVC) on the card using the SVC; generating a user validation code (UVC) pertaining to a validation of a user, the UVC code being generated based on a biometric reading taken via the biometric reader; communicating the SVC, the CVC, and the UVC to a transaction validator via a website; generating a validation result for the commercial transaction based on the SVC, the CVC, and the UVC; and displaying the validation result on the dynamic display. ### Claim 2 (depends on 1) The card of claim 1, the dynamic display comprising a column-row array of pixels. ### Claim 3 (depends on 2) The card of claim 2, the dynamic display further comprising at least one decoder coupled to the column-row matrix of pixels. ### Claim 4 (depends on 3) The card of claim 3, the at least one decoder comprising an analog de-multiplexer. ### Claim 5 (depends on 2) The card of claim 2, the column-row array of pixels comprising a set of transistors. ### Claim 6 (depends on 1) The card of claim 1, the IC comprising: a central processing unit (CPU); a display input/output (I/O) coupled to the CPU; a smart IC I/O coupled to the CPU; and an RFID I/O coupled to the CPU. ### Claim 7 (depends on 6) The card of claim 6, the memory medium being integrated within the IC. ### Claim 8 (depends on 7) The card of claim 7, the memory medium comprising at least one of the following: random access memory (RAM), read only memory (ROM), or flash memory. ### Claim 9 (depends on 6) The card of claim 6, further comprising: a smart IC contact coupled to the smart IC I/O; and an antenna coupled to the RFID I/O. ### Claim 10 (depends on 1) The card of claim 1, the card and the dynamic display further being powered by at least one of the following: an external power source, a capacitor battery, radio frequency coupling, a radio frequency coupling through RFID, or a smart IC contact. ### Claim 11 A method for automated card information exchange pursuant to user authentication, comprising: activating and powering up a card used to complete the user authentication; performing the user authentication by processing information obtained from at least one of the card and a user interaction through a host terminal or a live agent, the user authentication comprising: receiving a source verification code (SVC) via an imager positioned on the card, the SVC being generated based on the information; generating a card validation code (CVC) on the card using the SVC; generating a user validation code (UVC) pertaining to a validation of a user, the UVC code being generated based on a biometric reading taken via a biometric reader positioned on the card; communicating the SVC, the CVC, and the UVC to a transaction validator via a website; generating a validation result for the commercial transaction based on the SVC, the CVC, and the UVC; displaying the validation result and the processed information pursuant to the authorizing on a dynamic display integrated on the card. ### Claim 12 (depends on 11) The method of claim 11, further comprising requesting additional information pursuant to the processed information not being valid. ### Claim 13 (depends on 11) The method of claim 11, the card comprising: a dynamic display for displaying information; and an integrated circuit (IC) for controlling the dynamic display and for accessing a memory medium on the card, the memory medium storing the information. ### Claim 14 (depends on 11) The method of claim 11, the dynamic display comprising a column-row array of pixels. ### Claim 15 (depends on 14) The method of claim 14, the dynamic display further comprising at least one decoder coupled to the column-row matrix of pixels. ### Claim 16 (depends on 15) The method of claim 15, the at least one decoder comprising an analog de-multiplexer. ### Claim 17 (depends on 14) The method of claim 14, the column-row array of pixels comprising a set of transistors. ### Claim 18 (depends on 13) The method of claim 13, the IC comprising: a central processing unit (CPU); a display input/output (I/O) coupled to the CPU; a smart IC I/O coupled to the CPU; and an RFID I/O coupled to the CPU. ### Claim 19 A method for automated card information exchange pursuant to user authentication, comprising: powering a card by aligning an energy component of the card with a light source of a host terminal; activating the card used to complete the user authentication; performing the user authentication by processing information obtained from the card and a user interaction through at least one of the host terminal or a live agent, the user authentication comprising: receiving a source verification code (SVC) via an imager positioned on the card, the SVC being generated based on the information; generating a card validation code (CVC) on the card using the SVC; generating a user validation code (UVC) pertaining to a validation of a user, the UVC code being generated based on a biometric reading taken via a biometric reader positioned on the card; communicating the SVC, the CVC, and the UVC to a transaction validator via a website; generating a validation result for the commercial transaction based on the SVC, the CVC, and the UVC; displaying the validation result on a dynamic display integrated on the card. ### Claim 20 (depends on 19) The method of claim 19, further comprising requesting additional information pursuant to the additional authentication not being valid.
