4D for iOS: Sign and read barcodes from your app

January 26, 2021

Product

Actions using parameters have been available since 4D  v17 R5, and we’re constantly working to make your apps more and more interactive with enhanced mobile experiences. In 4D v18 R6, new parameter formats are available: Signature and Barcode!

Sign with your fingertip

With the Signature format, you can sign with your fingertip and send signatures directly from your app to the server. It’s a really nice solution to get your customer signatures after a package delivery, for example.

To integrate this feature into your app, just open the Actions section and select the Signature format for an image parameter!

Scan any barcode

The Barcode format allows any value that can be associated with a barcode (EAN13, EAN8, QR Code, etc.) to be extracted by simply scanning it from an Action form. This is a very convenient way to add an item reference by scanning a QR Code directly from your mobile application.

To add it from the project editor, just open the Actions section and select the Barcode format for a text parameter. Your mobile app will do the rest!

One very interesting thing about barcodes is that you can associate any string of characters to it and customize it easily. Many websites can help you to do this (just search for “QR code generator”).

Here’s an entertaining challenge: we have hidden a surprise text in this nice QR Code! Will you find it and share what you uncover with us on the forum?

Clue: the camera app of your phone might be helpful 🙂

Thanks to these two new parameters, you can add value to your apps so they can be more professional than ever before with a great user experience.

Don’t hesitate to give us feedback on the 4D forum and check out the documentation for more details. See you there!
