How to take a photo of a coin/banknote for optimal recognition?

 

·        Place the coin or banknote on a white background (for example, on a sheet of white paper).

·        Hold the phone parallel to the coin/banknote.

·        If the image is blurry (unsharp), take the photo again. In low light conditions, turn on the flashlight or flash on your phone (You can do it directly from the app).

·        It is not necessary to hold the phone as close as possible so that the coin / banknote occupies the entire square. However, make sure that it’s fully inside the square shown on the screen. The coin must not emerge outside the square.

·       In some cases, the flash is reflected in the coin or banknote as in a mirror. In this case, turn off the flash.

·       Please note, that the app cannot recognise tokens, medals, copies of non-existent coins, stamps, notes and other objects.
