System and method for improving data input by using word frequency to text predict input. Other systems and methods include analyzing words already contained in a document (e.g. spell checking and OCR) and using word frequency to create a proxy system to reduce the space required to store data, allowing for more efficient usage of storage and enhancing the embedded content of matrix codes. The system displays the most common words in a language based upon the previously entered or displayed word(s), or the previously entered or displayed character or characters. Words with the most common frequency of use with the prior word(s) are displayed in a table to enable the user to quickly select one of the displayed words for rapid data entry. The input device can be a touch-sensitive display or non-touch sensitive type device.
