Over 4,000 people in Sweden have had microchips implanted in their skin, which help them carry out every day activities.
The chip is very small; the size of a single grain of rice. The implant implant allows them to pay for things simply by swiping their hand> it can also monitor the user’s health, and can be used to get them into buildings, kinda like a key FOB.
Some people are worried about the safety of the implants, particularly when it comes to cyber-crime. Also there are concerns over who owns the data gathered.
The chips aren't available in the US... yet. The designers want to bring them here.
Pros: Don't have to worry about your wallet, or building keys. Also the health monitoring this is good.
Cons: It's creepy! Plus that's what an apple watch does, and nothing needs to be implanted into me!
