How it Works

Hunaja is an RFID access control system that enables users to remotely check who is logged in at a physical location by using the Web or a mobile phone.

Hunaja was developed in 2001-2002 by Aula Cooperative, which is a non-profit organization based in Helsinki, Finland. In addition to controlling the doors of the Aula space, Hunaja has three unique features:

Linkage to Aula's weblog - enabling online members to remotely see who is logged in at Aula's physical space

SMS access - enabling members to check who's there with their mobile phones

A speech synthesizer at the door - enabling online members to send greeting messages. The messages are announced by a computer voice when the recipient logs inat Aula's door


For three months (May-July, 2002), Aula issued a trial set of 50 RFID tags to its members. Of those 50 members, 9 members were selected for this user study. All of the participants were in the 20-35 year-old age group, and their use of the system was followed and recorded for two weeks during the month of July.
