A bank note is a piece of paper money issued by a central bank that represents a promise to pay the holder a certain amount of value
When you hold a $20 bill, you are holding a bank note. It is not backed by gold or silver sitting in a vault — it is backed by the government's promise that the note has value and can be exchanged for goods and services. The central bank (in the United States, the Federal Reserve) prints bank notes and puts them into circulation through commercial banks like yours.
Bank notes are different from coins, which are made of metal. Bank notes are made of a blend of 75 percent cotton and 25 percent linen, which is why they survive washing machines and years of handling. The paper itself is not what gives a bank note value — the government's backing and public trust in that backing is what does.
Every bank note has security features printed into it to prevent counterfeiting: a security thread embedded in the paper, color-shifting ink, microprinting, and a watermark. These features make it nearly impossible to forge a note without industrial equipment. If you receive a note that feels wrong or looks wrong, you can take it to your bank and they will examine it.
Key Takeaways
- A bank note is paper money issued by a central bank and backed by the government's promise that it holds value.
- Bank notes are made of cotton and linen, not paper, which is why they last longer and can be washed without becoming worthless.
- The Federal Reserve controls how many bank notes are printed and released into the economy to manage inflation and money supply.
- Security features like watermarks, security threads, and color-shifting ink are built into every bank note to prevent counterfeiting.
How bank notes enter the economy
The Federal Reserve does not hand bank notes directly to you. Instead, it prints them and sells them to commercial banks — your bank, Chase, Bank of America, credit unions, and others — at face value. When you withdraw cash from an ATM or ask a teller for $100, your bank is giving you bank notes that came from the Federal Reserve.
The Federal Reserve decides how many notes to print based on how much cash the economy needs. If people are using less cash and more credit cards, the Fed prints fewer notes. If there is a sudden surge in demand — like during the COVID-19 pandemic when people wanted cash on hand — the Fed prints more. This is one way the central bank manages the money supply and tries to keep inflation stable.
Why governments use bank notes instead of other forms of money
Bank notes are portable, durable, and hard to counterfeit compared to earlier forms of money. Before bank notes became standard, people used coins made of precious metals, which were heavy and straightforward to shave down (removing metal while keeping the coin). They also used ledgers and written promises to pay, which were straightforward to forge.
Bank notes solved both problems. They are light enough to carry in a wallet, they last for years, and the security features make them nearly impossible to copy without detection. A single $100 bill weighs less than a penny but represents the same value as 100 pennies.
Bank notes also give governments a way to control the money supply without having to mine precious metals. This lets them respond to economic conditions — printing more money during a recession to encourage spending, or printing less during inflation to cool down prices.
The difference between bank notes and other types of currency
Bank notes are one form of currency, but not the only one. Coins are also currency, and so are digital dollars in your checking account. The key difference is what backs them and how they are made.
| Type | What it is | Who issues it |
|---|---|---|
| Bank note | Paper money backed by government promise | Central bank (Federal Reserve) |
| Coin | Metal money, usually lower denominations | U.S. Mint |
| Digital currency | Money that exists only in bank accounts and payment systems | Commercial banks and payment networks |
| Cryptocurrency | Decentralized digital money not backed by a government | No single issuer; maintained by network users |
When you check your bank balance online, you are looking at digital currency — a number in a database that represents a claim on the bank's reserves. That number is backed by the bank's assets and the government's deposit insurance (up to $250,000 per account through the FDIC). It is not a physical bank note, but it is still money.
What happens to worn-out bank notes
Bank notes do not last forever. The average $1 bill stays in circulation for about 6.5 years before it becomes too worn to use. Higher denominations like $100 bills last longer — around 15 years — because people handle them less often and store them more carefully.
When a bank note becomes too damaged, faded, or torn, banks send it back to the Federal Reserve. The Fed destroys the damaged notes and prints new ones to replace them. This keeps the money supply stable and ensures that the notes in your wallet are readable and find.
If you have a torn or damaged bank note, you can take it to your bank and exchange it for a new one at no cost. The bank will send the damaged note to the Federal Reserve, and you will receive a replacement.
How bank notes relate to your bank account
Your bank account balance and the bank notes in your wallet are connected but separate. When you deposit cash into your account, the bank takes the physical notes and credits your account with that amount in digital form. The notes go into the bank's vault or are sent to the Federal Reserve. You no longer own those specific notes — you own a claim on the bank for that amount of money.
When you withdraw cash, the reverse happens. The bank takes digital money from your account and gives you physical bank notes in exchange. The bank gets those notes from its vault or from the Federal Reserve. The notes you receive are not the same ones you deposited — they are just notes of the same value.
This is why your bank account is insured by the FDIC up to $250,000, but the cash in your wallet is not. The cash is in your possession and is not at risk of the bank failing. The money in your account is a claim on the bank, so the government insures it in case the bank goes under.
Frequently Asked Questions
Can I refuse to accept a bank note as payment?
In the United States, all bank notes issued by the Federal Reserve are legal tender, which means they must be accepted as payment for debts. However, a business can refuse to accept cash and require credit cards or digital payment instead. Once you have received a bank note, you cannot refuse it — but a store can refuse to sell to you if you will not use an accepted payment method.
What should I do if I receive a counterfeit bank note?
If you suspect a note is counterfeit, do not spend it. Take it to your bank or the nearest Federal Reserve branch and report it. The bank will examine it and, if it is counterfeit, will not charge you for it — you will receive a legitimate note in exchange. Knowingly passing counterfeit money is a federal crime, so reporting it protects you.
Why do bank notes have pictures of dead presidents on them?
The Federal Reserve prints portraits of past presidents and other historical figures on bank notes to honor them and to make counterfeiting harder. Each denomination has a different person, and the portraits are printed with security features that are difficult to replicate. The choice of which figures appear is made by Congress, not the Federal Reserve.
Are bank notes still used if most people use cards and digital payments?
Yes. Even though digital payments are growing, bank notes are still widely used for everyday purchases, tips, and situations where digital payment is not possible. The Federal Reserve continues to print new notes every year. Some people also keep cash on hand for emergencies or situations where internet or power outages make digital payments impossible.
