Data Editing Formulas
The set of instructions programmed into the reader to define data fields and
than arrange them into a format is known as the data editing “formula.”
A maximum of four formulas can be resident in the reader’s memory at any
one time. If more than one formula is stored in memory, the reader will apply
the first formula to the decoded data. If the data format matches the format
(credit card, driver’s license, etc.) of the first formula, then it will re-arrange,
add, and drop the data fields as you have indicated and output the reformatted
data to the host.
However, if the data does not match the criteria spelled out in the first
formula, then the criteria of the second formula stored in memory will be
applied. And so on. This process will continue for each of the successive
formulas until a match is found. If no matches are found for any of the
formulas programmed into the reader, then the unedited data record will be
transmitted to the host by default (unless DO NOT SEND DATA has been
selected).
The number of formulas the reader will store is limited by the amount of
memory available. Caution should therefore be used when entering a number
of long formulas, as all might not fit.
