A number of employees like, Ann-Catherine Liska, have opted for the traditional pass for now.
'I don't feel that its necessary for opening doors or connecting with machines.' Ms Liska said.
Hannes Sjoblad, one of the tiny RFID (radio-frequency identification) chip developers, said they could be part of all future workplaces.
"We already interact with technology all the time. Today it's a bit messy - we need pin codes and passwords. Wouldn't it be easy to just touch with your hand? That's really intuitive."' Mr Sjoblad said.
He said its launch at the Sime office in Stockholm will provide more research into the technology.
"We want to be able to understand this technology before big corporates and big government come to us and say everyone should get chipped - the tax authority chip, the Google or Facebook chip." Mr Sjoblad said.
