1. A method comprising: sequentially, in an imaging scanner, capturing two or more images of a single document; identifying, in the imaging scanner, a first location in a first captured image where information to be decoded is located, analyzing each character in the first location, and producing a first string including both a corresponding character and a first confidence value for each character in the first location; determining, in the imaging scanner, that a first measurement of the confidence values in the first string is beyond a range associated with a first confidence threshold and; identifying, in the imaging scanner, a second location in a second captured image where information to be decoded is located, analyzing each character in the second location, and producing a second string including both a corresponding character and a second confidence value for each character in the second location; comparing, in the imaging scanner, the first confidence value for each character in an identified location in the first string with the second confidence value for the character in the same identified location in the second string; selecting, in the imaging scanner, a character from one of the first string or the second string with a higher confidence value; and producing and outputting, by the imaging scanner, a combined string including the selected characters.
