Cards and devices with multifunction magnetic emulators and methods for using same

Abstract

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable of communicating information to a magnetic stripe reader. Information used in validating a financial transaction is encrypted based on time such that a validating server requires receipt of the appropriate encrypted information for a period of time to validate a transaction for that period of time. Such dynamic information may be communicated using such an emulator such that a card may be swiped through a magnetic stripe reader—yet communicate different information based on time. An emulator may receive information as well as communicate information to a variety of receivers (e.g., an RFID receiver).

         6 . A payment card comprising:
 an electronic device operable of communicating information to a magnetic stripe reader;   a first magnetic shielding covering at least an entire side of said electronic device, wherein said magnetic shielding blocks said communicated information; and   a second magnetic shielding in the proximity of said electronic device, wherein said second magnetic shielding passes at least a portion of said communicated information.   
     
     
         7 . The payment card of  claim 6 , further comprising a battery. 
     
     
         8 . The payment card of  claim 6 , further comprising a processor. 
     
     
         9 . The payment card of  claim 6 , further comprising a display. 
     
     
         10 . The payment card of  claim 6 , wherein said magnetic shielding and said second magnetic shielding are of different shapes. 
     
     
         11 . The payment card of  claim 6 , wherein said magnetic shielding is a magnetic material. 
     
     
         12 . The payment card of  claim 6 , wherein said magnetic shielding is a magnetic material and said second magnetic shielding is a magnetic material. 
     
     
         13 . The payment card of  claim 6 , wherein said second magnetic shielding includes a space in alignment with an active portion of said electronic device. 
     
     
         14 . The payment card of  claim 6 , wherein said electronic device is disposed between said magnetic shielding and said second magnetic shielding. 
     
     
         15 . The payment card of  claim 6 , further comprising a button. 
     
     
         16 . The payment card of  claim 6 , further comprising a button, wherein said electronic device communicates said information based on a signal from said button. 
     
     
         17 . The payment card of  claim 6 , further comprising a detector, wherein said electronic device communicates said information based on a signal from said detector, said signal being indicative of a presence of said magnetic stripe reader. 
     
     
         18 . The payment card of  claim 6 , further comprising a button and a detector, wherein said detector is made operative based on a first signal from said button and said electronic device communicates said information based on a second signal from said detector, said second signal being indicative of a presence of said magnetic stripe reader. 
     
     
         19 . The payment card of  claim 6 , wherein said electronic device is provided on a printed circuit board. 
     
     
         20 . The payment card of  claim 6 , wherein said electronic device is provided on a multiple-layer printed circuit board. 
     
     
         21 . The payment card of  claim 6 , wherein said electronic device is provided on a flexible, multiple-layer printed circuit board.
