Did your Barcode scanner come with a list of 'commands' e.g. a user manual containing bar codes that you can scan to change the scanner's settings.
I'll use the Socket 7ci scanner as an example, since another user posted he's having the same issue while using this scanner.
Socket Mobile provides various support documents for this device on their site, including Command Barcodes Sheet 1D, which lists scannable barcodes to change the settings of the scanner.
In the section titled 'Data Suffix' , located on page 5, the function of the first listed barcode is described as "Suffix – Carriage Return (default) Configures the CHS to add a carriage return after decoded data." Scanning this barcode should fix the problem described by the Socket 7ci user that posted in this thread.
Note: Scanning this barcode will not fix your issue, as you're using a scanner from a different manufacturer, and barcode commands like these are usually manufacturer specific. But I'm willing to bet your scanner has the same option, as I believe it's a pretty standard feature for scanners in general.
When a barcode scanner scans a barcode and inputs it into whatever device it's connected to, like the iPad, it's basically doing the same thing you would be doing if you were to read a barcode and enter it into a computer/ipad using a keyboard. The scanner just does it a lot faster.
When you type a search phrase or a a url in a browser on your computer, you have to hit enter at the end to initiate the search. Just like you have to hit 'Send' after you're finished typing a text message. Setting the barcode scanner to suffix each scan with a 'Carriage Return' is basically just setting it to hit 'Enter'/'Return' each time after it finishes scanning a barcode. If, for whatever reason this setting is turned off, then the scanner doesn't 'press the 'Enter' key' after it's done scanning the barcode, so no item has actually been 'selected' in the Square app until the user selects the item manually.
