To pass building portals, badges and access cards could be replaced by a Bluetooth system connected to mobile phones, explains our columnist Anicet Mbida.

A mobile phone instead of an entrance badge? Some security companies like the Openpath startup are innovating, and offer businesses, and soon individuals, to unlock building portals using smartphones rather than access cards.

The replacement of badges and access cards by mobile phones has already begun. For you, it will change everything.

The phone is one of the few things we always have with us, which we pay attention to. While we tend to forget his card or access badge. Besides, you may remember the controversy: a company had proposed to implant the badge chip directly under the skin of employees, never to lose it.

New, slightly less painful systems are coming. There is always a box near the door. But he will communicate in Bluetooth with the phone. And if it is recognized, the door opens. There is not even to take out your mobile.

Yes, but if we break his phone, or if he is lost?

If you lose your phone, I think we will have bigger problems than entering a building. But unlike the badge, there is nothing to reprogram, just install an application on any phone, connect and we will find access. So it's much simpler and cheaper. There will no longer be a deposit that costs a fortune when you lose your badge.

It will also be much more secure. You know that today, in the offices, the card gives access to the elevator, the canteen, the photocopier and even the network. But these cards are very easy to copy, even remotely. While with a phone, you can ask for a fingerprint unlock for example. It is the Openpath startup that pushes this replacement of badges by the phones. The first installations are starting at the moment in companies.

It can also happen in car parks and apartment buildings?

This is the next step. And proof that all access will soon be managed by the phone: public transport, car start, parking and therefore, soon, access to the house and offices.
