When working with transactional data in structured formats for card operations, which approach is preferable? - Keep the current implementation to minimize changes - Develop a specialized parser from scratch - Use standard libraries considering banking data specifics - Ask developers for a ready-made solution

It is preferable to use standard libraries considering the specifics of banking data.

Justification:

• Standard libraries are usually well-optimized and tested over time, reducing the likelihood of errors.
• They provide support and updates, which are important for security and compliance.
• Taking into account the specifics of banking data (such as formats, masking, validation) allows adapting standard tools to specific tasks without the need for development from scratch.

Developing a specialized parser from scratch requires significant resources and time, and maintaining the current implementation may not ensure the necessary performance and reliability. Requesting a ready-made solution from developers may be justified, but it is better to first use proven tools and adapt them.
