People say "my card" and "my account" as if they were one thing, and in some countries they nearly are. This guide separates the two, because the answer to "which one am I comparing?" changes with the country.
The short version
A bank account is where your money is kept. A debit card is a way to spend it: every purchase or cash withdrawal is taken from the account straight away. The card has no balance of its own; it is a key to the account.
- Bank account
- Where your money is kept, held by a bank in your name. It has an account number.
- Debit card
- A card that spends from a bank account straight away. It has a card number and no balance of its own.
- Bank card
- The everyday name in mainland China for the card of an account. It usually means a debit card, but the same words can also cover a credit card, so read the card's own label.
- Routing number
- A nine-digit code in the United States that names the bank, not you. It goes with the account number when money is sent to or from an account.
- Card number
- The long number printed on the card. In mainland China it is usually the account number too; in the United States it is not.
How the two relate, country by country
| Mainland China | United States | Hong Kong | |
|---|---|---|---|
| What you open first | A debit card, together with its account | An account (checking or savings); the bank then issues a card on it | An account (savings or current); the bank then issues a card on it |
| Card number and account number | Usually one and the same number | Different: the account has an account number and a routing number, the card has its own number | Different: the card number is not the account number |
| Cards and accounts | Usually one card is one account | One account can carry several cards, and a replacement card leaves the account unchanged | The bank decides how many cards an account can carry |
What to look at when you compare
The account carries the monthly fee and how to avoid it, the minimum balance, the interest, an opening bonus and its deadline, and deposit insurance. See how bank-account bonuses really work and deposit insurance.
The card carries the network (Visa, Mastercard, UnionPay), the fee for spending in another currency, the ATM rules, the limits and where it works. The account's terms set these, but they land on the card.
A bank's page often writes both together. Read which line is about the account and which is about the card.
If you lose the card
The money is in the account, not in the card. Block the card first and the bank can issue another. How well you are protected if someone uses it before you report depends on the country and on how fast you are; see what to do in the first hour.
Three US examples
Each of these cards sits on an account, so they are read here the way they work: first what the account is, then what the card adds. They are what each company's own page said on 10 October 2026, not recommendations and not advice.
Capital One 360 Checking debit card. The free debit card on Capital One's 360 Checking account: no monthly fee, no minimum balance and no fee for foreign transactions. Capital One says there are no fees to open, keep or use the account, or for foreign transactions. The 70,000+ fee-free ATMs are Capital One, MoneyPass and Allpoint machines; at any other machine Capital One adds no fee, but the machine's owner may. Opening an account needs a Social Security or taxpayer ID number.
Fidelity Cash Management debit card. The debit card on Fidelity's Cash Management account, an account built for spending and cash: no foreign transaction fees, and fees charged by other banks' ATMs are reimbursed worldwide. If you choose to pay in US dollars at a foreign terminal the rate may be worse than the market rate, so pay in the local currency. ATM fees are reimbursed at machines showing the Visa, Plus or Star logo. The account is a brokerage account, not a bank account: uninvested cash is eligible for FDIC insurance, while brokerage holdings are not FDIC-insured.
Wise debit card (United States). The card on a Wise multi-currency account, for spending online and in stores in over 40 currencies and in 150 countries and territories. Wise says withdrawals are free of its own charge up to the first US$250, after which a small fee applies, and that independent ATM networks may add charges of their own. A card costs a one-time US$9.00 to order; a digital card can be added to Apple Pay or Google Pay straight away.
How RewardVane treats the two
The card library lists debit cards: Debit cards, by market and by bank, each pointing to its issuer. A card is what you recognise in your wallet.
The app has a bank-account page for the accounts you hold: which bank, what you opened it for, and an opening bonus's conditions and deadline. It keeps no balances and no full account numbers.
Questions people ask
Is a debit card the same as a bank account?
No. The account holds the money and the debit card spends it. In mainland China the two are usually opened together and the card number is also the account number, which is why people often say "bank card" for both. In the United States one account can have several cards, and a replacement card leaves the account unchanged.
Which one does RewardVane list?
The card library lists debit cards, because a card is what you can recognise in your wallet. The app has a separate place for the bank accounts you hold, where you enter them yourself.
If I lose the card, is the money gone?
No. The money is in the account, not in the card. Report the card lost and the bank can block it and issue another. How well you are protected if someone uses it first depends on the country and on how quickly you report; the guide on lost cards has the steps.
