Here is a screen-shot of the application:

Source code

TCL Source code:


The source may directly be executed, if a TCL virtual machine is present in the system.

Executable Program

Binaries for a couple of platforms may be generated using the LUCK service by dropping the source code in the code window.

There are no additional packages required

Pre-Build binaries

Binaries for some platforms may be downloaded below:

Windows binary::


Android binary:


Serial scanner connection

A serial scanner could be used with the program. Most USB-Scanners feature a virtual serial com (VCOM) mode, which may be used for this interface.

In this case, the interface name should be set within the settings pane.

The used scanner parameters are: no prefix, Symbology ID on, suffix: new line.

The status line shows a message if the interface was successfully opened. Otherwise, an error box is shown.

My compliant test scanner is CodeCorperation CR15 with a recent firmware (old had ECI reporting bug). Here is the configuration page in German laguage:

File PDF Acrobat iconECR15_CON9_SCI_2.pdf


the Android Support requires a certain knowledge how to get a debug signed APK on the device. It informs about old design OS from Android 10+.

The Android support currently features support for the following scanning devices:

  • ZXing "Barcode Scanner" app (currently very limitted due to bad Symbology ID support, will be continued)
  • Honeywell CN50, CN52 scanner

The Honeywell support requires the following settings:

gear-button -> Honeywell settings -> Scanning -> Internal Scanner
  "+" for new profile, name it "scanlink"
  - click on scanlink profile->Data Processing settings:
    - Off: Wedge, Launch Browser, Scan to Intent, Launch EZ Config
    - On: Data Intent, click on text "Data Intent" to open options
      - Action: de.elmicron.action.BARCODE_DATA

None of those scanners are compliant with respect to ECI processing resulting in poor performance.
There is room for improvement. Ideas welcome.

DMRE Datamatrix Rectangular Extension

What is DMRE?

Data Matrix Code with additional rectangular formats.

The example code below shows an extended rectangular Data Matrix with a module size of 8x64 fitting well in the available space on the object:DMRE

Message about DMRE from Dennis Priddy, one of the original Datamatrix developpers

"I love it! Your implementation of the Extension could not be more perfect in its simplicity, execution and effectiveness. And yes, it does make me a bit proud to know that Data Matrix can still help solve real-world problems – when in the hands of some very smart people.
Thank you!
Best regards and best wishes,
Dennis Priddy"

Message from Henri Barthel,  ISO/IEC JTC 1/SC31 Chairman

"We have just published a new DataMatrix rectangular barcode (ISO/IEC 21471), which can be engraved onto very small medical instruments and equipment for hospital theatres and used to track them. We are also working on a similar approach for a rectangular QR code (ISO/IEC 23941)."

Current Data Matrix Rectangular Formats (not DMRE)

 Data Matrix following ISO16022 ECC200 already features the following rectangular formats:

8 x 18 10 6 3  dm8x18
8 x 32 20 13 8  dm8x32
12 x 26 32 22 14  dm12x26
12 x 36 44 34 22  dm12x36
16 x 36 64 46 30  dm16x36
16 x 48 98 72 47  dm16x48

Use-Cases for extended Data Matrix Rectangular formats

The following use-cases require additional rectangular sizes if higher data amount must be encoded:

Highly rectangular marking surface


Typically, the height of 8 modules is used and should be extended to a higher width if more than 13 alphanumeric characters are encoded. The upper example encodes a standard product ID following EDIFICE guidelines for electronic products.

Curved surface

 dmre ultrakain

Curved surfaces like tubes should have a code at minimum height (typically 8 modules) and an increased width. The example features a PPN code on a drug.

Code height limited by printing technology


Continuous InkJet technology is limmited in print height while print width may be extended.

In consequence, a maximum module height of 26 modules should not be extended. Nevertheless, the requirements on data capicity for pharmaceutical products exceed the capacity of a 26x26 symbol and thus rectangular symbols help to solve this issue.

Especially the various serialization projects with inline printing processes mostly by inkjet technologies have shown a clear need for these new rectangular formats.


The ISO/IEC standard is published 2020-02-03 and may be purchased here:

DMRE was developped within the working group ISO/IEC 1 / SC 31 / WG 1 as project 70947

I want to thank the very active members of this group who made this possible.

The following presentation presented at ISO/IEC JTC1 SC31 WG1 on 2021-04-13 containing some typographic issues which will be fixed with edition 2 of the standard:

File PDF Acrobat iconWG1_21471_DMRE_2021_Tokyo.pdf

The prior versions of DMRE published by AIM and within DIN16587 had another set of chosen formats. The column "Standards" below includes the document covering the format.

The formats 24x32, 24x32 and 26x32 were present in DIN16587 and are not adopted by ISO/IEC21471 due to not sufficient width to height ratio.
New formats with height of 8 and 12 were added, as a use cases are seen for marking of round objects, specially in the scope of UDI.
New formats with height of 20 and 22 were added to support contact inkjet printing with an additional text line below the code.

technical support

paperedi emblem rotated 1200dpi grayPaperEDI is the solution for transport labels and shipping documents providing EDI functionality by 2D-Code. There is a direct link between barcode and EDI whenever logistical operations are involved. Therefore, both techniques can complement each other. One 2D-symbol can carry the whole shipping information equivalent to ane page of a delivery note.

The PaperEDI is suitable for a variety of applications. The "P'EDI" standard contains the document types "Offer, Order, Delivery note, Invoice, Order Confirmation, Consignment Replenishment/Consumption, Credit Note and Return Delivery".

PaperEDI is also suitable as "SET CODE" for products, e.g. an overpack or equipment, which includes sub-components. The "SET CODE" can carry all included parts with it's variables.

In the P'EDI standard of the revision of Jan. 7, 2021, the UDI formats have been harmonized, no matter how the UDI on the product is structured (IFA, GS1, HIBC, ISBT), in P'EDI every UDI-DI is applied with the ASC data identifier "54P". This DI indicates that products are UDI relevant  and encoded in P'EDI in the same format as stored in the UDI databases GUDID, EUDAMED, etc.
