CodeCheck V1.1
Copyright (C) Richard Smedley 1998
==================================

Easily check VAT registration codes and credit card numbers, to test
whether or not they are valid. See below for details about why you might
find this useful!

CodeCheck is shareware, but fully functional. If you use it, then please
register...


INSTALLATION
------------

This program is compatible with all EPOC32 machines, like the S5 and
Geofox.

1. Make sure "Show system folder" is selected in your system prefs.

2. Create the folder "System\Apps\CodeCheck" on any drive. Now copy the
   following files into this folder:

        CodeCheck.aif
        CodeCheck.app
        CodeCheck.hlp

The CodeCheck icon will now appear on your Extras bar.

Use the Options screen to change between using the program to check VAT
registration codes, and using it to check credit card numbers.


CHECKING VAT REGISTRATION CODES
-------------------------------

Have you ever received an invoice from your electrician, only to find that
he has charged you a hefty 17.5% in VAT? Or are you worried that a plumbers
bill scrawled on the back of a cigarette packet might not be genuine?

If so, then this could put your mind at ease...

All companies who are registered to charge VAT are required by law to
supply their VAT registration code on all bills, receipts and invoices.
CodeCheck can test these 9-digit VAT codes to see whether or not they are
valid - and if you ever get a bill with an invalid code then you will
instantly know that they are *not* registered to charge VAT, and that they
are breaking the law by trying to make you pay VAT for their services.

To check a VAT code, simply type the 9-digit number into the box and press
the return key. A message will instantly appear telling you whether or not
that code is valid. You can now be sure that nobody will ever try to make
you pay VAT when they are not genuinely registered to do so!


CHECKING CREDIT CARD NUMBERS
----------------------------

This could be essential for anybody who runs a small business, and needs to
take credit card orders over the telephone.

When somebody gives you their credit card number, you can enter it into
CodeCheck to instantly find out whether or not that number is valid. This
could be extremely useful for protecting yourself against fraud, and also
gives you a quick & easy way of checking that the customer has read their
card number out properly.

Please remember though that CodeCheck only checks the validity of the
number; it doesn't test whether or not that account actually exists, or
whether their credit limit is big enough to cover the transaction. You
still need to use a credit referral agency to do that!


HOW TO REGISTER
---------------

This program is shareware. The unregistered version is fully functional,
but there is a slightly annoying delay between entering a number and the
program telling you whether or not it is valid.

When you register, you will be sent a personal registration code to enter
into the program. This will make your copy of the program fully registered,
and will remove the delays.
