Title: CodeCheck 1.2 Description: Check credit card numbers & VAT registration codes Author: Richard Smedley Home page: http://www.cix.co.uk/~rsmedley/s5/ INTRODUCTION ============ CodeCheck allows you to easily check credit card numbers and VAT registration codes to test whether or not they are valid. In the UK, all VAT registered companies are required by law to supply their VAT registration code on all invoices and receipts. When somebody tries to charge you 17.5% VAT on their bill, you can use this program as a quick way of checking their VAT registration code to make sure they are genuinely registered to charge VAT. If the program says that they are using an invalid code, then you will know that they are trying to rip you off! Being able to test credit card numbers could be invaluable for anybody who runs a small business. For example, if you accept credit card orders over the telephone then you could enter the customers credit card number into CodeCheck to instantly find out whether or not they have given you a valid credit card number. INSTALLATION ============ This program is fully compatible with all EPOC machines, including Psion S5/5mx, Revo, S7, Oregon Scientific Osaris, etc. Installation uses approx 12K of disk space. Simply select CODECHECK.SIS to install it on your Psion, and everything should be installed for you automatically. No additional modules or OPX's are required. HOW TO REGISTER =============== This program is shareware. The unregistered version is fully functional but there is a slight 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. After you've registered, all future updates are free. All you have to do is download them.
