Abstract
Disclosed is a data communication system and method for communicating data between a first integrated circuit card having a first antenna and a first memory and a second integrated circuit card having a second antenna and a second memory, wherein the first antenna is magnetically coupled with the second antenna through a device having an antenna to transmit data from the first memory to the second memory.
Claims38
A data communication method for communicating data, comprising the steps of:
- providing a first integrated circuit card having a first antenna and a first memory;
- providing a second integrated circuit card having a second antenna and a second memory;
- magnetically coupling said first antenna with said second antenna through a device having an antenna;
- and
- transmitting data from said first memory to said second memory by transmitting the data from said first antenna directly to said second antenna without said device reading the data.
