Apparently the Face ID facial recognition system thinks kids look the same – it's fair enough really - I think they all look the same, and all babies look like Winston Churchill no matter what their mums think.

However, in a security guide, Apple recommends that children under the age of 13 do not use Face ID due to the probability of a false match being significantly higher for young children.

It is the kids' fault of course. Apple says this was because “their distinct facial features may not have fully developed”. We assume they are talking about the children and not Apple’s face scanning software.

The Tame Apple Press claims that it does not matter as few young children are likely to be given a £999 iPhone, false matches are also more likely for twins and siblings. In all those situations, the company recommends concerned users disable Face ID and use a passcode instead.

Another area where Apple is having problems is facial coverings. Apple says that “Face ID is designed to work with hats, scarves, glasses, contact lenses and many sunglasses”. 

But if the coverings have to be transparent to infrared light and the system can see the eyes, nose and mouth. While some fabrics are more transparent to infrared than they may seem, that means iPhone users who cover their faces may be forced to rely on a passcode when out and about.
