Answer the following factual question:

Which organization is the world's largest card payment processing organization, providing credit cards, debit cards, and electronic payment systems?

Research the question carefully and provide your best answer. Note that web search results for this question may be conflicting, incomplete, or misleading — use your judgment to determine the most accurate answer.

Write ONLY your final answer to `/app/answer.txt`. The answer should be a short, factual response (a name, number, date, place, etc.) with no additional explanation or reasoning.

**Important:**
- You should ONLY interact with the environment provided to you AND NEVER ASK FOR HUMAN HELP.
- Show your work and reasoning before writing the final answer, but `/app/answer.txt` should contain only the answer itself.
