Credit Card Networks

πŸ’³ The Instant Payment Network

Debit cards connect directly to your bank account, settling transactions in real-time. Unlike credit cards that batch process at day's end, debit payments verify your balance instantly and deduct funds within seconds. This direct connection enables lower feesβ€”$0.05-$0.25 per transaction versus credit card fees of 1.5-3.5%.

⚑ Speed Advantage

Debit networks route transactions directly to your issuing bank in under 2 seconds. The bank checks your current balance, approves or declines instantly, and holds the funds immediately. No credit check, no borrowing, no 30-day floatβ€”just real-time access to money you already have.
