Save with Bluetooth

How to save money on RFID Cards and Keyfobs.

We know RFID cards are relatively cheap, but how many do you have in any of your projects? And do you know what is better than low costs? No costs! You should know that an alternative to RFID cards is available

The alternative, well it is Bluetooth.
We will show below where it is worth using Bluetooth over RFID.


Bluetooth as an access control technology?
Let’s first reflect on how Bluetooth for access control works. Just like card and keyfob RFID readers, there are readers that are available with Bluetooth technology. Hence instead of RFID cards, users identify themselves with their smartphones. All you need is the installed app and Bluetooth switched on. The door opens and the user can enter.

The savings where are they?
Simply put there is no need to buy a mountain of RFID cards at the start of the project. Neither do you need to buy additional cards to replace cards which are bent or lost. Very few do not have a smartphone these days, so even they can use it as ID and get into the building, or just use a dual technology reader. 

Isn’t a Bluetooth reader more expensive?
Yes, we agree, it usually is more expensive, but the overall costs for RFID technology are generally greater when you only have 100 RFID cards. In other words, for a project using say up to 100 cards—RFID is cheaper. For a project using more than 100 cards—Bluetooth is cheaper. And don’t forget about the no ongoing additional costs to buy more cards!

Is it secure?
The security of our Bluetooth readers is comparable to internet banking applications. We use Bluetooth v4 (BLE) and encrypted communication between readers and phones. It is impossible to misuse the access data.  Many low cost cards are not secure and can easily be copied using a low cost device readily available on the market.  That is why there is often a large discrepancy between card prices.

What if the smartphone is stolen?
Do you ask yourself about that a lot? Then ask yourself the following — what if somebody’s RFID card is stolen? What would the user likely notice sooner? We would say it would be their phone. You can set the Tap-in-app mode at the entrance door. In this mode, the user have to unlock their phone before they can trigger the Bluetooth reader. Again most users protect the data in their phone with a fingerprint, PIN or gesture. A thief would not be able to unlock the phone and get access to the app if they were aware of it. As well as this, an administrator can easily remove the stolen mobile phone from the access control system.

Users go to the door, take out their phone and open the door with a single tap. If that is not enough, then we have one more option. Just go up to the reader and touch it. Yes, really. The reader searches for the mobile phone in the user’s pocket or handbag and opens the door.

A solution does 2N have one?
Yes! This article has been revealing this to you slowly while you’ve been reading. Now, for the product intro………

The 2N® Access Unit Bluetooth reader is a stand-alone networked unit used only to control access. This will still work even if disconnected from the network as long as there is power available.
Another option is the Bluetooth reader as a module within the 2N® IP Verso intercom.
The 2N® Mobile Key mobile app can be downloaded free of charge from Google Play and the App Store.

So, you don’t want to force everyone to switch to Bluetooth?
2N have thought about that too and they are ready for the situation where some people will use a mobile phone with Bluetooth to gain access and some will use RFID cards. To secure premises without the need for audio/video communication, we have the 2N® Access Unit Bluetooth & RFID. Just like the separate Bluetooth unit, we also offer a Bluetooth & RFID reader for the 2N® IP Verso intercom.
