iBeacon transmitters use Bluetooth 4.0 tech, and can be dialed in to a range of different distance sensitivities, which means that it can work on a hyper local basis, sending specific information only when you’re in the area for demos and workshops, for instance, or next to a particular product display. At the same time, it can provide general alerts to anyone who enters a store’s doors.
The upside for retailers using iBeacons is two-fold: First, they can offer more specific, targeted information to customers, which in theory helps with customer service (and could cut down on minor requests that would normally occupy staff). Second, iBeacons provides them with hyper-local data regarding customer movements within a store (apps could contain an opt-in for allowing use of that info). That kind of granular look at shopper behaviour could pay huge dividends in terms of helping formulate evolving retail strategy.
Can your mobile phone become a replacement for manually typing in a password? That’s the promise of a new application called Knock, launching today, which uses an iPhone paired with a Mac desktop or laptop computer to log you in to your locked machine. The system takes advantage of the newer low-energy Bluetooth technology to enable the connection between the two devices, allowing you to just knock (you know, knock, like on a door) on your iPhone to login. But the company has ambitions to expand beyond unlocking computers, and envisions bringing Knock to browsers to log into websites, and eventually letting you “knock” to open anything, including even your home’s front door, perhaps.
If you’ve looked at the hardware specifications for a top of the line handset at any point in the last few years, there’s a good chance that you’ve seen NFC listed on the spec sheet. But despite the age of NFC, it hasn’t yet become the norm for all smartphones. If you’re content with an older handset, or can’t quite justify springing for the latest top of the line model, you may be wondering what all the fuss is about. So here’s a rundown of what NFC is, how it works, and what it can be used for.
NFC stands for “Near Field Communication” and, as the name implies, it enables short range communication between compatible devices. This requires at least one transmitting device, and another to receive the signal. A range of devices can use the NFC standard and can be considered either passive or active, depending on how the device works.
