doesn't give me that option and i'm stuck with the card transmitting, any way to shield it? >> there are wallets to keep the credit card with the rfid in the wallet that will shield it from sending out the signal. that way you dope have to worry about someone sitting next to you and grabbing it. only time to transmit is pulling it out and you set it next to, you know, an rfid reader. >> i should look for a wallet like that. what do you think the future is of this? passing fad or you think it's here forever? >> it's here forever and it's going to get worse. this is my personal opinion, at some point we're all going to have rfids. might be in our fingers and require it. where everything on it. driver's license will be an rfid chip, our credit card number, all of our information will be on the chip and you have a bunch of scanners that can read it. >> a new world out there. >> whole new world and scary world at that.
