Simple QR Code Stamps This PDF is a QR Code stamp file containing three QR Code stamps. Installation instructions are provided on the next page. Each stamp has a single barcode field that covers the entire stamp surface (Figure 1). The amount of data encoded by the QR Code is limited by the size of the barcode field. All the stamps here are limited to 75 characters. To change this limit, resize both the stamp page and the barcode field covering the page.

Figure 1 – QR (Quick Response) Barcode, 27 characters

Stamp #1: The first stamp has a static text value that is hard-coded into the value calculation for the barcode field. This value is changed by editing the value calculation on the Properties Dialog for the barcode field.(Figure 2).

Figure 2 – A hard coded QR Code value is easy to setup.

Stamp #2: The second stamp acquires its QR Code value from the “baseURL” property of the document being stamped. This “baseURL” property is set on the “Advanced” tab of the Document Properties dialog (Figure 3). This is an example of acquiring dynamic stamp data from the target document. The script can be modified to automatically acquire the data in any number of ways.

Figure 3 – Any document property that can be accessed through JavaScript can be a data source for a dynamic stamp

Stamp #3: The third stamp displays a popup input box asking the user to enter text or URL data (Figure 4), when it is applied to the target document. This text is then encoded into the QR Barcode.

Figure 4 – Any text can be entered into a QR Code. But the maximum number of characters is limited by the physical size of the stamp

Stamp Installation Please install this stamp file in one of the two Acrobat Stamp Folders. Local User Folder: Stamp files placed in this folder are only visible to one user. However, this is also the only location where Acrobat will edit the stamp file when stamps are added or deleted using the stamp manager. To locate this folder you will need to run the following code from the Console Window. app.getPath("user","stamps");

Application Folder: Stamp Files placed in this folder are visible to all users on the system. Acrobat considers stamps in this folder to be immutable. Typically this folder is located at: <Acrobat Installation>/Acrobat/plug_ins/Annotations/Stamps It can also be found by running the following code in the Console Window: app.getPath("app","stamps");

The Following Pages are the Actual QR Stamps.
