Epicenter is a co-working space that houses more than 100 companies and about 2,000 workers. It started its microchip implant service in January 2015. To-date, about 150 workers have subscribed to the ID microchip system using a near field communications (NFC) technology. It's the same technology being used in contactless credit cards or mobile payments.

The Daily Mail reported that the technology itself is not new as some companies have already been using it to track deliveries and pet owners using them as virtual collar plates for their pets. It's just the first time that the technology was used for a large-scale  ID microchip system for humans.

According to Hexus, employees with the implanted microchip can wave a hand to open doors, operate printers, faxes, and copiers, or even purchase drinks from smoothie machine.
