The alphabetic character or number is perpendicularly marked on the plastic ring up and down (it enables it to read from three directions). In the case of an alphabetic character and a number, a horizontal line is located in the bottom, in the case of two numbers, no horizontal line, in the case of two alphabetic characters a horizontal line between them(see Photo.).
