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.
