Payment Processor

Overview

The Payment Processor is a Ruby application designed to process payment data from a CSV file and generate a detailed report of the processed payments.

Features

• Processes payment data from a CSV file.
• Identifies the card type (Visa, Mastercard, AmEx) based on the card number.
• Checks for card expiration and skips processing expired cards.
• Generates a detailed report including total payments and dollar amounts by card type.

Installation

1. Clone the repository:

   git clone <repository_url>

2. Install the required dependencies. This project requires the timecop gem for mocking time:

   • Name
   • Card Number
   • CCV
   • Zip Code
   • Expiration Date (MM/YYYY)
   • Amount (in cents)
   • Card Type

   Example:

   Name,Card Number,CCV,Zip Code,Expiration Date,Amount (in cents),Card Type
   John Doe,4242424242424242,123,12345,12/2023,5000,Visa
   

2. Run the payment processor script with the path to your CSV file as an argument:

   ruby payment_processor.rb path/to/your/input.csv

   Example:

   ruby payment_processor.rb inputs.csv

3. View the generated report.
