MIT researchers have come up with the brilliant usage of radio tags that can be used to reduce card thefts, radio tags will be working as per the signals of your fingers and you do not have to use your signature to make payments. The trial of this new technology by MasterCard has come out successfully. The working of radio tags depends on the radio signals, which can be turned off and on to prevent theft.



This technology is really wonderful and has come out in the right time when there were maximum thefts happening across the US.
