Anyone with a wrist tattoo may want to be wary of the Apple Watch.
Early users of the new Apple Watch have reported the device malfunctioning for anyone with a wrist tattoo.
The issue first arose on Reddit when a tattooed user complained that his watch would frequently become disconnected and reported inaccurate heart rate results.
Dozens of other tattooed users reported the same issue following this.
Apple Watch requests a security PIN immediately after detecting that it has left an owner’s wrist, meaning that those affected are forced to repeatedly enter their code.
It appears that the darker the tattoo, the worse the problem is. Apple explained that the watch measures heart rate by analyzing light absorption through the skin. Why they didn’t facotr skin coverings into account seems baffling.
The Reddit user posted: “So I thought my shiny new watch had a bad wrist detector sensor.
“The watch would lock up every time the screen went dark and prompted me for my password. I wouldn’t receive notifications. I couldn’t figure out why especially since the watch was definitely not losing contact with my skin.
“I decided to try holding it against my hand – my left arm is sleeved and where I wear my watch is tattooed as well – and it worked.
“My hand isn’t tattooed and the Watch stayed unlocked.
“Once I put it back on the area that is tattooed with black ink the watch would automatically lock again. Just wanted to give anyone a heads up about this issue because I don’t see it mentioned anywhere in Apple’s support documents.”
While the wrist detection feature can be turned off, it stops Apple Pay from working.
