In a glimpse of what the future may hold， tiny microchips are being implanted in humans so they can unlock doors and get into their computers without using keys or passwords.

Sydney woman Shanti Korporaal has had two implants inserted in her hands which she now uses like she has superhuman powers， the Adelaide Advertiser reports.

Her goal now is to completely do away with her wallet and cards so that she can lead a futuristic lifestyle， and the sky is the limit as to what can be done next."You could set up your life so you never have to worry about any password or PINs ."she said， "Its the same technology as Paypass， so Im hoping youll be able to pay for things with it."

With Opal you get a unique identification number that could be programmed into the chip. Any door with a swipe card ... it could open your computer， photocopier. Loyalty cards for shops are just another thing for your wallet.

The implant is almost impossible to spot as it is just the size of a grain of rice. The microchips can be used in the same way as a smartphone and store complex data.

Ms Korporaal has even set up a distribution service for the implants with her husband， Skeeve Stevens， called Chip My Life in what is a niche market.

However， although it is a niche market at the moment it is gaining interest as a firm in Sweden proved when it gave its employees the choice of having chips implanted instead of a work pass— more than 400 took up the offer.
