Push, not pull
• An OCT credits the card instead of debiting it
• The recipient shares only a card number, no bank details
• Funds usually post in seconds to minutes
Gates before money moves
• Limit checks bound velocity and per-transfer ceilings
• PAN eligibility confirms the card can receive a push
• Funding is authorized before the OCT is submitted
Reversals and returns
• A reversal unwinds a push the network still owns
• An issuer return sends funds back after the credit posts
• Both restore the payer funding source
