Discover Bank and Capital One 360 are two of the longest-running online banking platforms — both backed by major financial companies with decades of experience. They offer similar products (savings, checking, CDs, money market) with no monthly fees, but each has a standout feature the other can’t match: Discover’s 1% cashback checking and Capital One’s in-person Café network. Here’s the full comparison.
TL;DR:Discover Bank wins with its unique cashback debit account (1% on debit purchases, up to $360/year), strong customer service, and competitive rates. Capital One 360 wins with cash deposit access (Cafés and ATMs), a larger fee-free ATM network, and its credit card ecosystem integration.

Savings rates are nearly identical. The difference is typically $0-$25/year on $25,000 — not enough to choose one over the other based on savings APY alone.

No other major bank pays cash back on debit card purchases. If you use your debit card regularly, Discover’s cashback checking is worth $60-$360/year — significantly more than Capital One’s 0.10% interest on a typical checking balance.

Capital One wins on ATM access — more ATMs, cash deposit capability, and higher daily withdrawal limits. Discover’s ATM network is still strong at 60,000+, but the inability to deposit cash is a limitation shared with many online banks.
