We would like to mention that we provide a free, GPL, open source PHP_Class Real Time Transaction Processing Module that drives our free, open source, GPL Secure Payment Gateway and Merchant Accounts. Download at: http://www.openecho.com/php/echophp-1.4.tar.gz Supports all Credit Card as well as online check transactions. Since we are the Merchant Processor and Gateway in one, we can provide the same services at a much lower cost. Cybercash will make you pay a $495 license fee for their gateway/software, and a monthly access fee of $15 to $25. Here is a price comparison with them: http://www.openecho.com/rate_compare.htm Support and source code are available at www.openecho.com Main site is www.echo-inc.com Thanks to PHP!!!
