CreditCard 1.8 build: 9639 released: 2008-03-06 compiled with: Java 1.8.0_131 Jet jet12.0-pro-x86/1.8.0_131 Validates Credit Card Numbers. Copyright: (c) 1999-2017 Canadian Mind Products. signed Java Applet (that can also be run as an application). Download from: http://mindprod.com/products1.html#CREDITCARD View HTML to run this program online at: http://mindprod.com/applet/creditcard.html ---- Notes: You must install the Java JRE to use this program. See http://mindprod.com/jgloss/jgloss/jre.html This hybrid program is mainly designed to be used as an Applet in a browser but is can also be used from the command prompt, e.g. under Windows command.exe or JPSoft tcc.exe, formerly called the DOS box. Just clicking the programs in a directory listing will not do anything useful. Just typing the program names at the command prompt will not either. This program requires a manual install! See below. I put out an avalanche of free software into the world, and submit PAD files to hundreds of distribution sites, but I rarely hear back from anyone. What's happening? Does it all just work fine? It is so complicated nobody can figure out how to use it and they give up on it? It is it useful? Since everyone has the source, do people just fix the programs to their liking themselves? Did you have trouble installing? Do I presume you know too much? I would be happy to hear from you about your experiences, positive or negative and your requests for improvements. A one-line email to roedy@mindprod.com would be great. ===> Free <=== Full source included. You may even include the source code, modified or unmodified in free/commercial open source/proprietary programs that you write and distribute. May be used freely for any purpose but military. For more details on this restriction, see http://mindprod.com/contact/nonmil.html If you include any Canadian Mind Products code in your own applications, your app too must be labelled non-military use only. http://mindprod.com/contact/nonmil.html All Java jars and source code are included. If you need the class files or Javadoc, you will have to build them yourself. To streamline the zip downloads, class files and Javadoc have been removed. ---- Prerequisites: This program runs under any OS that supports Java, (e.g.W2K/XP/W2003/Vista/W2008/W7-32/W7-64/W8-32/W8-64/Linux/LinuxARM/LinuxX86 /LinuxX64/Ubuntu/Solaris/SolarisSPARC/SolarisSPARC64/SolarisX86/SolarisX64/OSX/AIX...) so long as you have <><> Java version 1.8 <><> or later installed (32-bit or 64-bit Java). See http://mindprod.com/jgloss/installingjava.html for details. ---- Installing on a PC: Download source and compiled jar files to run on your own machine as an application or Applet First install a recent Java JDK or JVM. See http://mindprod.com/jgloss/installingjava.html. To install, extract the zip download with WinZip (or similar unzip utility) into any directory you please, often J:\ -- ticking off the use folder names option. To run as an application, type: java.exe %JAVA_OPTIONS -ea -jar J:\com\mindprod\creditcard\creditcard.jar {put any parms here} adjusting as necessary to account for where the jar file is. ---- Installing on a MacIntosh: Use Safari to download source and compiled jar files to run on your own machine as an application or Applet. Safari will automatically unpack the zip into ~/Downloads (version 10.5) [or on the Desktop (version 10.4 and earlier)]. First install a recent Java JDK or JVM. See http://mindprod.com/jgloss/installingjava.html. You may optionally move the download tree to a permanent home. I don't have a MacIntosh, just a PC, so I can't test my Java programs for Mac compatibility. In theory they should work without problems, but in practice that does not always happen. If you have problems please, let me know, preferably with screenshots and complete verbatim error messages. To run as an application, without parameters, just double click the jar file. To run as an application with parameters, in bash shell type: open Terminal.app cd ~/Desktop java.exe -ea -jar com/mindprod/creditcard/creditcard.jar {put any parms here} adjusting as necessary to account for where the jar file is. ---- Rebuilding: The zip already contains the necessary jar files, so unless you modify the program, there is no need to recompile the source or rebuild the jar. Configure.java basedir="E:/" in rebuild.xml to the drive where your files are. Configure.java your certificate name with environment SET cert=mindprodcert2017rsa Configure.java your certificate password with environment SET jarsignerpassword=sesame Use ANT and rebuild.xml, not build.xml, to recompile and recreate the jar. ---- Use: The CreditCard Validator will help you tell: 1. if a credit card number is valid, 2. which credit card vendor handles that number. It is a simple Applet to demonstrate the use of the ValidateCreditCard class. It validates the prefix and the checkdigit. It does *not* contact the credit card company to ensure that number has actually been issued and that the account is in good standing. It will also tell you which of the following credit card companies issued the card: Amex, Diners Club, Carte Blanche, Discover, enRoute, JCB, MasterCard or Visa. ATM cards use a different secret scheme which this program does not handle. Unfortunately, there is not even a reliable way to tell an ATM card from a credit card just by the number. It is primarily designed to be included in your own Java program, though it can be used standalone or as an Applet. To install, Extract the zip download with WinZip, available from http://www.winzip.com (or similar unzip utility) into any directory you please, often C:\ -- ticking off the "user folder names" option. To run as an application, type: java.exe -jar C:\com\mindprod\creditcard\creditcard.jar adjusting as necessary to account for where the jar file is. ---- Version History: 1.0 1999-08-17 1.1 1999-08-17 1.2 1999-08-17 not enough and too few digits messages. catch NumberFormatException when too big to fit in long.\ 1.3 1999-08-19 ignore dashes in numbers 1.4 2005-06-17 stomped BAT files, added about box, cleaner GridBag 1.5 2005-12-16 add Javadoc 1.6 2006-03-04 reformat with IntelliJ, add Javadoc 1.7 2007-05-17 add pad and icon. 1.8 2008-03-06 convert to jdk 1.5. add build number to title. simplify with enum. -30-
