Advice needed on POS equipment for Delphi application !!

Hi all,

I have written a program for a local medical outlet - basic database
stuff - everything going well thus far. Stage two of development requires
intregration of some POS (point of sale) gear, namely the following:

(1) Receipt printer
(2) Smart-card or mag-card reader
(3) Cash drawer
(4) Bar-code sticker printer
(5) Bar code reader (only perhaps!)

So the questions are:

(a) What products should I be looking at (suppliers/brands/models etc)
(b) What kind of extra programming am I getting myself into
(c) What *min* spec should I have for the PCs (by way of ports, etc)

Obviously I want to keep the cost as low as possible. Does anyone know
perhaps of a small dot-matrix printer that would have say two feed rolls
... one for stickers, the other for receipts?

Appreciate any answers copied to me by email!  (tec...@cargo.iol.ie)
remove the capitals for the old anti-spam measure!

Thanks a lot,

- Allen.

Star produces small receipt printers. There are others but don't know them.
This is a specialised arena. Check with stores already using this kind of
equipment. Search the net. Search thru magazines.

There's a significant difference between a smart-card and a mag-card.
Mag-card just has a magnetic strip. Smart cards have a chip on them (memory
or processor/memory).
A suggestion: If this is only for in-house use (identification of
customers) go for the bar-code reader and give people a card with a
bar-code on it. This way you only have to buy/implement/maintain the
bar-code reader for both identification of customers and products.
If people already have identification cards issued by some organisation ask
them for the format and their recommended equipment.
They come in two flavors: with their own ISA-card or with a
serial(RS232)-port connector.

Don't know anything about it but should be quite simple.

> (4) Bar-code sticker printer

Some possibilities come to mind:
I'd guess it's quite possible to do the sticker printing before or after
business hours. If so you could change the rolls on the receipt printer and
use it to print the stickers (make sure that the printer can be used to
print bar-codes!!!).
You could buy a specialized printer for the bar-code stickers.
If you need reporting there will probably also be a 'normal' printer. If
the batches of stickers are large enough you could easily use this printer
for the stickers (Small batches in this case will usually lead to a lot of
wasted paper unless you make your program so that it can start printing on
any position of the page. (if this is too cryptic mail me and I'll explain
further).

Lots and lots of them around.
Basically three types:
- with their own ISA-card and proprietary driver: disadvantage: you might
need a new driver if your going to a new/updated OS.
- connected via RS232(serial)-port
- connected via the keyboard-port. Here your program will believe that the
information scanned came from your keyboard.

Check out the mag's, the net and talk to shops that already have this kind
of equipment.

Receipts and barcode printing: is basically like creating reports.
Barcode reader: accepting input, wether you let the user type in a produkt
identification number or scan it doesn't matter, you'll have to validate
the input and match it with your product table.
Smart/mag-cards: accepting input, validating the input (might need some
encoding), match it with your customer table.
Cash-drawer: This is just opening the cash-drawer, isn't it?

Depents on what you're going to buy. If you require two printers you'll
want a second LPT-port.
You might need some extra serial-ports

Don't know.

Some door access vendors use cards which have a bar-code overlaid with opaque
(to visual light) tape . So individuals cannot read the bar-code but the card
reader (? using UV or ir light) can read the card.
