RFID+ Filemaker RFID Reader Application

Application Details (con’t)

The Scan button activates a script in FileMaker called “scan button” which contains the Open URL script

step containing the callback. (  g. 8 )

 g 8. The “scan button” script containing the callback in the Open URL script step.

The command follows the same general syntax as the pic2shop callback, but contains a pre x (“r d://”)

that the RFID+ Application is speci cally designed to use.

Remember that the URL needs to be encoded to handle certain characters. For example, the $ sign is

replaced with %24.

Of special note is that, in the callback is a) the script that will be run, when the scan is complete (what

script is ‘called back’ ) and b) where the parameter is set that the script will run with.

In the callback shown:

a) the script is ‘Scan’, in the string %3Fscript%#DScan

b) the parameter is in the string %26param%#DEAN. EAN is a placeholder that the RFID+ Application

uses to return the scan result as the actual parameter.

Note: In future releases, the ‘EAN’ string in b) can be set as a variable to tell the RFID+ Application which

type of data to return that is encoded on a RFID tag, as there are multiple types.
