Got your keys? Got your wallet? What about your privacy?

People in Sweden are implanting microchips beneath their skin, and according to NBC News, those microchips contain everything from digital identification to digital keys and digital currency.

But not everyone is fond of the development. One woman interviewed by NBC News says the idea makes her "feel less human" and more "like a robot." Another woman agrees, as she does not like the idea of implanting a foreign object inside her body.

In the U.S., Twila Brase of Citizens' Council for Health Freedom compares it to putting a barcode on individuals -- something she says is depersonalizing as well as a threat to privacy.

"People can say anything they want about it being encrypted, but the fact of the matter is the more things are computerized, the easier it is for hackers to get into all of this sensitive data. And now here you would be carrying it around with you," Brase tells OneNewsNow. "It could include your banking information, your financial information, all of this kind of information which is highly valuable to hackers and to thieves, and there it is in a little chip, available to people who would even choose to accost you and remove that chip and take it with them."

While there is no central registry to track how many people in Sweden are chipped, one source interviewed by NBC News estimates between 5,000 and 10,000.
