WASHINGTON – A high tech office complex in Sweden is trying a new approach to giving employees access to their offices and office equipment. They’re getting “chipped” – having tiny RFID (radio-frequency identification) chips inserted into their hands.

The chip lets workers enter the complex, enter individual offices and even operate the photocopier, BBC reports.

The chip is the size of a grain of rice and feels like an injection when inserted.

Some 700 people in the complex will be offered the chance to get chipped.

Eventually, those who do also will be able to use their chip to buy food in the café.

Some in the Epicenter building are looking forward to the chips, but others are worried about the process.

BBC Technology Correspondent Rory Cellan-Jones had the chip inserted into himself to see how the process works. Watch the video:
