When a barcode scanner is said to be POS (Point of sale) does this mean by default that it scans automatically without having to use the trigger?

I want to add a barcode reader to an App I made, and know little about them. From what I gather some are automatic...it will read a barcode as soon as it sees  one, others you have to pull the trigger. I need an automatic one for POS. There are alot for sale on eBay, but when I search for info on the product, they don't talk aboout that...is that because by default they read automatically?
Thanks for any input.

Hi pigeonbr,

There are a bunch of different hardware models for scanners.  Some are trigger-based, some just project the laser no matter what.

We've used the Wasp scanner as a pos device and while it is trigger-based, it also comes with a stand that you can rest the device on and it converts it to a downwards facing automatic setup.  The trigger rests on the stand which presses it in.

Ok..I see...so I think you just answered a question I had been asking myself...the stand just pushes the trigger...all I have to do is hard-wire the switch on the scanner and that takes care of any reader that you must use the trigger.

When you do use your stand, does the scanner send a carriage return after scanning the code? From what I gather, these scanners are pretty plug and play...that is, you connect it to the computer (USB lets say) and if you have a box on screen where the cursor is, the scanner will automatically read the data into the box, right? Then if the scanner sends an auto carriage return, I can program my edit box to do what it wants with the data?

Am I way off or am I on the right track?
Thanls for your input. Feel free to elaborate if I'm way off.

Pretty much.  Even a rubber band will do the trick in a pinch.

You generally put that information in the barcode if possible.  So if you are scanning to a data entry screen and the Tab key sends the cursor to the next input and the Enter key saves the entry, you code the barcode like so:

data1^tdata2^tdata3^crlf

Where ^t is the setting for a tab and ^crlf is the setting for carriage return/line feed or what have you.  The codes for the various barcodes are fairly well documented.

If you are not creating the barcodes yourself, you want to make sure you can append and prepend codes by configuring the scanner.

Thanks very very much. I know this wasn't difficult but I needed to be sure of a few things...now I can jump.
