USB barcode scanners are fairly straight forward. I've used off-brand desktop scanners, honeywell, zebra, etc. As far as keyboard wedge mode, they all mostly work the same. The one thing that might make a difference is if the scanner can add prefix/suffix characters to the scan.
Agree with @dkhayes117 response, just to add a brand to the list of scanners you can look into, I am working on a project currently and we are implementing Keyence scanners. They have been working well for us in your exact scenario. I haven't had any issues thus far with them.
Is there a tablet that can scan the bar codes to a focused input on a Perspective page directly?
So far, I have only heard about tablets scanning to applications then manually copy/pasting the text from the app to the page.
I mean to ask is there a tablet with a scanner that can be implemented as keyboard wedge?
I saw some Zebra ETXX models, but I can't tell if they are only scanning to an application only or if the tablet scanners can operate as a keyboard wedge.
I found Zebra documents at least on ET6x has the keyboard wedge functionality.
They called it OCR wedge, not sure why, but they describe the functioning the similar way.
I may be misunderstanding you but, is the tablet going to be running Perspective and you would like to scan the barcode directly into the field?
If you are using tablets with a camera to run the application, you may be able to take advantage of using the camera coupled with barcode session events to handle what you are trying to accomplish just to throw out another possible idea.
If you're using an android or iPad tablet and run the perspective app, you can use the barcode scanning functionality built into the perspective workstation app on the devices. If using Windows it doesn't support it unfortunately, but we just ordered some Windows tablets not long ago for a client that have a camera barcode scanner, but it hasn't been the most reliable (or I'm using it wrong).
We are currently using the zebra TC26 which is easy to configure, just make sure it sends each key individually.
Great for scanning, but calling quality could be better.
We started with the camera but that does not support continues scanning which was a requirement.
It's equiped with the SE4710.
We use the custom/parameter in views for communication with the ERP system, on some cases the value goes to tags for automatic time registration in cases the machine has no digital communication.
It's very easy to use in a session/view/tag.
If the scanner is setup as keyboard wedge, won't text be entered into the focus input upon a scan?
I had thought prefix and suffix were for when using the bar code scanner session technique so that text from the scanner would be delineated from general text from the keyboard.
I have setup a pre and postfix for the entire project.
As far as I know the value will not be entered in the focused element when a barcodescanner element is available.
Any input field will not be changed using the barcodescanner, the data is send over using an intent activity. Verified with the demo App.
