Hi

The current device is a coin operated Multi drop bus dispenser -
person puts in a $1 coin, machine dispenses $1 worth of liquid, $5 =
$5 worth etc

The owner wants to stop using coins and have everything built on
barcodes so that:
Each customer has bottles of various sizes, each with a barcode and
related to an inventory for managing who can dispense how much liquid
and bottle size. The customer places bottle in fron of scanning
device, database does a quick calculation and if cust has enough
credit, tells dispensing device to dispense correct amount.

Hello All,

I have been asked to build a simple database that will operate and
track a liquid dispensing device. The machine is run in a multi-bus
drop (coin operated basis) but I need to make it run on a barcode
scanner basis. I have no idea if this is even possible (or if there
are examples that have already been done) I have never set up a
barcode scanner before and certainly never had to interface with a
machine like this.

I would really appreciate if someone could point me in the right
direction.

Many thanks
John

Im not entirly sure what you are trying to do, is this for some kind of
embedded system or for a PC?...

Some barcode scanners work by plugging inbetween the keyboard and the
computer so its transparent, when you scan it just sends keys as tho youd
typed them into the keyboard...

Whats being scanned? What do you mean on a barcode scanner basis?

I don't believe that a Windows operating system is robust enough for
an application that requires weeks of uninterrupted operation. Linux
might be a better choice. I would go with Java for development...
that would give you a reliable system that uses a minimum of resources
and doesn't require a fast processor. Most processor issues are heat
related and are directly proportional to the amount of calculations
being processed per second. If you want reliability - keep the
processor cool!
