Recently I came across a web service over at ProgammableWeb that generates barcodes. This might be useful if you scan barcodes, and want an alternate method to create barcodes in your FileMaker solution.
The web service, Barcodes4.me, is a RESTful service and requires no API or fee. It supports a handful of barcodes types, as well as QR codes, and requires a simple URL call. Using FileMaker 12’s Insert from URL you can send a query to this web services and insert a barcode image into a container field.
Given that this is a free service, there is no guarantee how long it will remain available or a free service. The types of barcodes available also are limited. This is still a good option to keep in mind when developing and testing a mobile solution with barcodes. I have included a small demo file to show this in action.
