What do you mean by "Non-USB"? Serial? PS2?

I'd imagine that with either PS2 or USB would work the same, as the OS handles the text input all the same. If it's some other input, it might be different-- you might need to know if PHP has an interface to a certain device driver.

What exactly are you trying to do? Surely this is a problem for the client interface, not the server?

hi

i'm having a similar problem. I'm trying to get a barcode reader to work on an embedded system, but for now just on my desktop running debian with a 2.4.26 kernel. I've got a ps2 barcode scanner in a ps2/usb connector connected to the usb port.

the kernel registers the ps2 connector, but i have no idea how to access the device. Any ideas. At the moment it seems i need to write a device driver for the device, but would love it if there was an easier way.

what device would I have to access to read the scanner? /dev/usb/??? i can't seem to find it. also i'm using the usbkbd driver. I know its limited, but i can't get the keybdev driver to work on the embedded system....

thanks in advance

The joy of barcode readers. I have worked with serial readers and basically as long as you can read from a serial port and detect Start and End of Text you can usually frame the data. With that said the wand when inserted into the well or whatvever will dumps its data quite rapidly. Thus your application needs to be able to read the serial feed rapidly. So is this PHP-able? This sounds a little dicey given the small window that exists for the data dump. Ultimately if the wand you are using is more sophisticated (i.e. allows a delay) then you may be able to read it. As always good luck

We build linux based POS systems with PHP/MySQL. We plug a good USB scanner (try cobra) and it reads the barcode and translates to text. There's not a script side parsing from code39 to text that you have to do, that's what the reader does. If your reader sends delimiters, (like mag stripe readers do) you will need to strip those but that's easy enough. We've used serial port readers but its always a pain getting compatible drivers etc. Just drop a few more bucks and go USB to save headaches.

Interesting discussion; I actually have a barcode scanner that I could experiement with, and maybe I can make something out of it - or at least make it work, for starters.

Hi starsunited. I'll need to do that work soon. A co-worker did it and as far as I remember when talked to him he used handhelds with bar code readers. Basically the handheld has WinCE so he was able to read the barcode and the handheld passed the information directly to a PHP page that handled the code. This is a pretty good thing because if you have a wireless connection you can make live connections to a master database to process orders. I'll try to find more information about how they implemented it.

Thanks RamiroS.

Hey,

I have web based ERP system and going to attach barcode reader to the web interface.

Any idea how to use webbased interface for checkout process?

It seems that Javascript has to wait for "\n" (end of string) and Postback the form.
In my case to avoid Postback I'm going to use AJAX.

Does anybody have expirience with barcode and webforms ?

Thanks.
