What is a prepaid debit card and how does it work? You can’t redeem the rewards as actual cash during ATM withdrawals, but you can apply your cash-back balance to your next in-store or online purchase. Serve rewards you with 1% back on all your purchases, which hit your account as soon as the transaction settles. Not to be confused with the free reload card, the Serve American Express Prepaid Debit Account helps you earn cash back for purchases you would be making anyway - a true rarity for a prepaid card. Reload locations: Over 45,000 across the US Reward rates: 1% back on all online and store purchases Other fees: Card purchase is $1.50 at retail stores or free if ordered online ATM fee: Free at MoneyPass ATMs or $2.50 elsewhere
