The craze over the Apple Watch, following its preorder on April 10 and the shipping of the device from April 24 notwithstanding, the device seems to have a major flaw.

Latin Post reports that there have been several claims over social media outlets like Twitter and Reddit alleging that the smartwatch does not function when it is worn over their tattoos.

However, this does not come as a surprise. It is well known that the Apple Watch utilizes the wearer's heart rate to find out whether you are wearing the device. The Apple Watch does this by utilizing infrared sensors that possess the ability to see through the user's skin, irrespective of the natural skin colors or scars, and determine the heart rate.

Now, the problem is that when a wearer has a tattoo under the sensors of the smartwatch, it is unable to see through the synthetic ink that colors the tattoo - this is at least ture in some cases. In effect, this causes the device to believe that it is not being used. When this happens the wearer cannot use certain apps of the device, such as Apple Pay, make calls or receive notifications.

Actually, the Apple Watch is intended to be more helpful for the fitness and wellness conscious consumer. An Apple Support page for the smartwatch offers a little breakdown on the manner in which the gadget is supposed to operate.

Here is an extract from the Apple Support page that reads, "The heart rate sensor in Apple Watch uses what is known as photoplethysmography," the support page reads. "This technology, while difficult to pronounce, is based on a very simple fact: Blood is red because it reflects red light and absorbs green light. Apple Watch uses green LED lights paired with light?sensitive photodiodes to detect the amount of blood flowing through your wrist at any given moment. When your heart beats, the blood flow in your wrist -- and the green light absorption - is greater. Between beats, it's less. By flashing its LED lights hundreds of times per second, Apple Watch can calculate the number of times the heart beats each minute -- your heart rate."

Meanwhile, CNN Money reports that one of its Reddit users have hit upon a simple fix by turning off the wrist detection. However, when the user does this, it also disables the heart rate monitor. Although this will permit the wearer to receive notifications, he/ she will still not be able to use Apple Pay or receive calls when the wrist detection is turned off.
