In Berlin, Germany, a start-up company is hoping to revolutionise the way we get into our homes. The idea involves swapping a traditional metal key for a Kiwi Ki, which is a little plastic square which automatically unlocks your door as you get close. It is essentially a transponder and uses radio-frequency identification technology. The new device is said to be the first of its kind to connect to a smartphone app, which means that doors can also be opened remotely.
According to the Co-founder of Kiwi.ki, Claudia Nagel, she had the idea for Kiwi in November 2007. She had just had her first son and was standing in front of an apartment building, with a baby in one arm and bags over the other. At the time, it was raining and it was cold and she couldn’t find her key. “That’s when I thought there had to be an easier way to open doors,” she said.
Over 15-thousand households in Berlin have access to the system, and recycling collectors in the city are also testing it out.
