payment through sponsors(#238)

[husain537404]

The revised version of the original payment policy makes several key changes to improve clarity, structure, and inclusivity.

1. More Precise Terminology
   The original text used terms like "recipients" and "attendees," whereas the new version uses "supported participants" and "sponsors" for greater clarity about who is involved.
   This helps differentiate between those receiving financial assistance and those providing it.

2. Acknowledging the Financial Burden More Explicitly
   The original version briefly mentioned that waiting for reimbursement "can be a financial burden on scholarship recipients."
   The new version expands on this by stating that some participants may not have the financial resources to cover upfront costs, making the issue clearer and more empathetic.

3. Stronger Recommendation for Direct Payment by Sponsors
   The original version encouraged conferences to cover costs directly but framed it as an optional best practice.
   The new version strongly recommends that sponsors cover major expenses whenever possible (e.g., flights, hotels, deposits).
   This shifts responsibility from participants to sponsors, reducing financial strain.

4. Introduction of a Practical Solution: Virtual Credit Cards
   The original version only mentioned reimbursements, direct payments, or lump sums without alternative solutions.
   The new version introduces virtual credit cards (e.g., Ramp) as a practical, modern solution for handling expenses that cannot be prepaid.
   This eliminates the need for participants to pay upfront while giving sponsors better financial control.

Overall Impact
The new version shifts the burden away from participants and onto sponsors, making financial support more accessible.
It also provides an actionable solution (virtual credit cards) instead of just listing payment methods.
The message is clearer, stronger, and more structured, making it easier for sponsors to adopt best practices.
