Read Barcode outputs the digits and characters encoded in a barcode on a page.
Find Barcode is an extraction method available to Data Fields in a Data Model. It is used to read barcodes on a document and populate fields in a data model with their encoded text.
There are almost 30 different types of barcode symbologies (the way data is formatted and read from barcodes) Grooper can read.
Find Barcode vs Read Barcode
Read Barcode differs slightly from Find Barcode. Read Barcode reads a barcode at the time of extraction. Find Barcode reads Layout Data obtained during an Image Processing activity. For Find Barcode to work, you must get barcode information ahead of time using Barcode Detection or Barcode Removal IP commands. Read Barcode detects the barcode and reads the result at the same time, during data extraction.
Why choose one over the other? It mostly depends on workflow and computing resources (or personal preference). You may want to get barcode data ahead of time, freeing up computing power during data extraction. In that case, Find Barcode would be more suited to your needs. If computing power during the Extract activity is not an issue, Read Barcode may be better for you.
Read Barcode is a new method of extracting barcode data into a Data Model in version 2.80. Prior to 2.80, barcode data was extracted by setting up data element overrides for a Data Field on individual Document Types. This required drawing a box on a sample document called a Field Zone where you expected to find the barcode for each Document Type you needed and set up the Barcode Reader from there. Read Barcode simplifies the whole process by setting up the Barcode Reader directly on the field being extracted rather than a field override on a Document Type. This means if you have multiple Document Types extracting a barcode to the same field, you only need to configure the Barcode Reader once.
Barcodes are used in a variety of ways. The most common usage is for product labeling, which can be used to track items in inventory or for accounting purposes. In a healthcare setting, barcodes may be used for patient identification to access patient data, such as medical history or allergy information, or to create SOAP Notes or manage medication. They also may be used to separate and index documents.

The most common form, UPC-A, consists of 12 numerical digits, which are uniquely assigned to each trade item.|
|Upce||UPC-E. This symbology differs from UPC-A in that it only uses a 6-digit code. To allow the use of UPC barcodes on smaller packages where a full 12-digit barcode may not fit, a 'zero-suppressed' version of UPC was developed called UPC-E, in which the number system digit and all trailing zeros in the manufacturer code and all leading zeros in the product code are suppressed. Encodations are a compressed form of UPC A. The DataString property holds the full uncompressed UPC A encodation for this symbology.|
|Aztec||Aztec is public domain 2D barcode symbology, formally defined by the ISO/IEC 24778:2008 standard|
How To: Configure the extractor
Before you begin
There are very little prerequisites for Read Barcode to work. You pretty much just need documents and a Content Model with a Data Model and Data Fields to populate. However, you will need to familiarize yourself with which symbology you are using in order to set up the extractor.
Set the Value Extractor to Read Barcode
Navigate to the Data Field or Data Column you wish to populate in your Data Model. Select the "Value Extractor" property. From the dropdown list, choose "Read Barcode".
1. Expand the "Value Extractor" property by double clicking it to reveal Read Barcode's properties.
2. Select the "Detection Settings" property and press the ellipsis button at the end of it. These settings control how the barcode is found and read, including what symbologies are used.
3. A new window will appear to configure settings in order to read barcodes. At bare minimum, you must select at least one barcode symbology using the "Barcode Symbologies" property. The settings in this window are the same as the Barcode Detection IP Command. Refer to the Barcode Detection article for more information on setting up these properties.
Configure the remaining properties
There are two other properties available. "Page Filter" and "Value Pattern".
The "Page Filter" property restricts the extraction to specific page numbers. If blank, Read Barcode will search all pages for barcodes and return their result. Page numbers may be entered as a comma separate list. Entering "1" would run on the first page. Entering "1, 3, 5" would run on the first, third and fifth page. You may also enter a range of "X to Y" pages. Entering "1 to 5" would run on the first to fifth page. Using negative numbers will start at the end instead of beginning of the document. Entering "-1" would run on the last page, "-1, -3, -5" would run on the last, third from last and fifth from last page, "1, -1" would run on the first and last page, and so on.
The "Value Pattern" property allows you to write a regular expression to validate the barcode's value. Part or all of what it written here must match the value extracted from Read Barcode. For example, the barcode bellow is a Code39 barcode embedded with the phrase "HELLO WORLD"
Since you expect to see alphabetic characters, any result with numerical digits would be a bad result. You could set the Value Pattern to
[^\d]+ to match anything that is not a digit character. The result would populate the field with no issue
On the other hand, if you expected to see digits and no alpha characters, you could write a different Value Pattern, such as
\d+ to match any string of digits. In that case, the field would not populate because it does not match the Value Pattern.
|Detection Settings||None||These settings control how the barcode is found and read, including what symbologies are used. Select the ellipsis button at the end of the property to bring up the Detection Settings property window. The settings in this window are the same as Barcode Detection IP Command. Refer to the Barcode Detection article for more information on setting up these properties.|
|Page Filter||The "Page Filter" property restricts the extraction to specific page numbers. If blank, Read Barcode will search all pages for barcodes and return their result. Page numbers may be entered as a comma separate list. Entering "1" would run on the first page. Entering "1, 3, 5" would run on the first, third and fifth page. You may also enter a range of "X to Y" pages. Entering "1 to 5" would run on the first to fifth page. Using negative numbers will start at the end instead of beginning of the document. Entering "-1" would run on the last page, "-1, -3, -5" would run on the last, third from last and fifth from last page, "1, -1" would run on the first and last page, and so on.|
|Value Pattern||The "Value Pattern" property allows you to write a regular expression to validate the barcode's returned value. Part or all of what it written here must match the value extracted from Read Barcode.|
