Abstract

A card may be formed using two or more printed circuit boards. Each printed circuit board may include one or more RFID antennas, RFID chips and a processor. A processor on a board may transfer data to one or more RFID chips on the same board. Alternately, a processor on a board may transfer data to one or more RFID chips on a different board via conductive terminals between boards. Data stored in one or more RFID chips may be erased after being communicated to an RFID device via an RFID antenna or after a configurable timeout period elapses. A card and a mobile device may include more than one RFID antenna to increase efficiency, reliability, and/or a number of data channels that may be communicated.

Claims

exact text as granted — not AI-modified
1 . A device, comprising:
 a first board including a first RFID chip and a first RFID antenna; and a second board including a processor, wherein first data is transferred from said processor to said first RFID chip via conductive terminals between said first and second boards and wherein said first data is communicated from said first RFID chip to a first RFID communication channel via said first RFID antenna.   
     
     
         2 . A device, comprising:
 a first board including a first RFID antenna; and   a second board including a first RFID chip and a processor, wherein first data is transferred from said processor to said RFID chip and wherein said first data is communicated from said first RFID chip to a first RFID communication channel via said first RFID antenna.   
     
     
         3 . The device of  claim 1 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip via conductive terminals between said first and second boards and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, said first and second data being the same. 
     
     
         4 . The device of  claim 1 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip via conductive terminals between said first and second boards and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, said first and second data being different. 
     
     
         5 . The device of  claim 1 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip via conductive terminals between said first and second boards and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, wherein a difference between said first and second data forms information for a third RFID communication channel. 
     
     
         6 . The device of  claim 1 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip via conductive terminals between said first and second boards and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, wherein a first difference between said first and second data forms information for a third RFID communication channel and a second difference between said first and second data forms information for a fourth RFID communication channel. 
     
     
         7 . The device of  claim 1 , wherein said first data is erased from said first RFID chip after said first data is communicated from said first RFID chip to said first RFID communication channel. 
     
     
         8 . The card of  claim 1 , wherein said first data is erased from said first RFID chip after a delay period has expired. 
     
     
         9 . The device of  claim 1 , wherein said first and second boards are encapsulated, said encapsulation being laminated between first and second lamination layers. 
     
     
         10 . The device of  claim 1 , further comprising a dynamic magnetic stripe communications device. 
     
     
         11 . The device of  claim 2 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, said first and second data being the same. 
     
     
         12 . The device of  claim 2 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, said first and second data being different. 
     
     
         13 . The device of  claim 2 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, wherein a first difference between said first and second data forms information for a third RFID communication channel. 
     
     
         14 . The device of  claim 2 , further comprising a second RFID antenna, wherein second data is transferred from said processor to a second RFID chip and wherein said second data is communicated from said second RFID chip to a second RFID communication channel via said second RFID antenna, wherein a first difference between said first and second data forms information for a third RFID communication channel and a second difference between said first and second data forms information for a fourth RFID communication channel. 
     
     
         15 . The device of  claim 2 , wherein said first data is erased from said first RFID chip after said first data is communicated from said first RFID chip to said first RFID communication channel. 
     
     
         16 . The device of  claim 2 , wherein said first data is erased from said first RFID chip after a delay period has expired. 
     
     
         17 . The device of  claim 2 , wherein said first and second boards are encapsulated, said encapsulation being laminated between first and second lamination layers. 
     
     
         18 . The device of  claim 2 , further comprising a dynamic magnetic stripe communications device. 
     
     
         19 - 20 . (canceled)
