Section 5

DATA EDITING

In addition to adding preambles, postambles, and terminator characters, the

Omni can also rearrange, drop, or add to the data it reads from a bar code or

magnetic stripe. This enables the data to be sent to the host in the exact format

expected by the application software, thus eliminating the need for software

modiﬁ cations.

To accomplish this, the decoded data is divided into smaller blocks of data

known as “ﬁ elds.” in accordance with established standards such as ISO,

AAMVA, and CDL.* With these ﬁ elds of data deﬁ ned, the order in which

they are sent to the host can be changed. They can also be added or eliminated

as needed.

Speciﬁ cally, the following functions can be performed:

Validate the Data

: Data read from a bar code or magnetic stripe can be

checked for length, matched to a preset value, or restricted to a certain type of

input (i.e., Code 39, Code 128, etc.).

Parse the Data

: The data can be divided into separate ﬁ elds.

Rearrange the Data

: The ﬁ elds that make up one track of data can be

transmitted to the host in any order desired, regardless of the order in which

they occur on the magnetic stripe itself.

Insert Character Strings into the Data

: Additional ﬁ elds of characters can be

created and inserted into the data at any place on any track.

Delete Character Strings from the Data a Record

: Fields of characters can be

deleted from the data before it is transmitted to the host.

Search for a Character String

: Data can be searched for a speciﬁ ed string of

characters. This string of characters can then be deleted, moved, or modiﬁ ed

using other Data Editing commands.

Duplicate Fields

: Fields of data within a track can be duplicated and

transmitted to the host as many times as desired—and in any order desired.

Insert Time Delay

: Time delays can be inserted between ﬁ elds of data to give

the host time to complete an operation.

* Please see Appendix D for standard magnetic stripe data formats.
