What Are Blank Credit Cards Used For? Legitimate Uses and Federal Penalties

Blank credit cards are unprinted plastic cards with a magnetic stripe or EMV chip and no account data, cardholder name, or bank branding on them. They are used legitimately to test payment terminals, to produce employee ID badges, and to create gift cards and loyalty cards for businesses that want their own branded plastic. They are used illegitimately to clone stolen payment card data onto a working counterfeit. The cards themselves are legal to buy, but federal law treats possession of fifteen or more counterfeit access devices, or possession of card-encoding equipment with intent to defraud, as a felony carrying up to fifteen years in prison.

What a Blank Card Is

Industry insiders call these “white plastic” because the cards ship without logos, colors, or printed text. Every card has a magnetic stripe on the back capable of holding account data across two or three tracks, and some versions include a blank EMV chip on the front for contact-based transactions. Without personalization, the card does nothing at a register or an ATM. Turning it into something usable, lawfully or not, requires a card printer, an encoder, or both.

Legitimate Uses

Payment System Testing

Software engineers and payment terminal manufacturers rely on blank cards. When a company develops a new point-of-sale system or updates card reader firmware, it has to run thousands of test transactions without touching real accounts. Engineers encode test data onto blank cards and swipe or insert them to verify that the system reads each track correctly, handles errors, and rejects malformed data. It is routine, unglamorous work, and it is one of the main reasons blank cards exist as a commercial product.

Employee ID Badges

Large organizations buy blank cards in bulk to produce employee identification. With a thermal card printer, a company can print its logo, the employee’s photo and name, and encode access credentials onto the magnetic stripe or chip. The same card can open doors, log attendance, and pay for lunch in the cafeteria.

Gift Cards and Loyalty Programs

A local gym, bookstore, or salon can create branded membership or gift cards without signing up for a bank-issued card program. Entry-level card printers start around $750 to $1,300, which makes in-house printing practical even for small operations. Professional printing services that handle the job externally typically charge between $5 and $12 per card, depending on order volume and features like holographic overlays or RFID encoding.

The Illegitimate Use: Credit Card Cloning

Cloning turns a blank card into a working copy of someone else’s payment card. A criminal obtains stolen card data, usually through a skimming device attached to an ATM or gas pump, a retailer data breach, or a dark-web marketplace selling card numbers in bulk. That data gets written onto the magnetic stripe of a blank card using a magnetic stripe reader/writer. Once encoded, the blank card is functionally identical to the victim’s card for any transaction that relies on the stripe.

Cloned cards work at point-of-sale terminals and ATMs where the card is physically present, which often bypasses the fraud filters built for online transactions. Fraudsters target high-value, easily resalable goods or pull cash from ATMs. The victim usually doesn’t notice until a fraud alert fires or an unfamiliar charge shows up on a statement, and that lag is what makes the scheme profitable.

When Possession Becomes a Federal Crime

The primary federal statute is 18 U.S.C. § 1029, which criminalizes fraud involving “access devices.” The term is broad: it covers physical cards, card numbers, account numbers, PINs, and any other code that can be used to obtain money or goods.1Office of the Law Revision Counsel. 18 USC 1029 Fraud and Related Activity in Connection with Access Devices Buying a blank, unencoded card is legal. Criminal liability attaches when the cards carry stolen data or when encoding equipment is possessed with intent to commit fraud.

The main penalty tiers:

Prosecutors rarely charge § 1029 alone. In skimming and cloning cases, federal grand juries routinely add wire fraud, bank fraud, money laundering, and conspiracy counts. The charge that adds the most real time is aggravated identity theft under 18 U.S.C. § 1028A, which applies whenever someone uses another person’s identification during a fraud-related felony. A conviction carries a mandatory two-year prison sentence that must run consecutively, meaning the judge adds it on top of whatever sentence the underlying fraud conviction produces.2Office of the Law Revision Counsel. 18 U.S. Code 1028A – Aggravated Identity Theft There is no probation option. A cloning operation that might produce a 10-year sentence under § 1029 lands at 12 years minimum once the aggravated identity theft count attaches.

Intent is the hinge. A print shop stocking white plastic for corporate ID orders is doing what the industry does every day. The same shop stocking the same cards next to a magnetic stripe writer and a spreadsheet of stolen account numbers is looking at a federal case.

If Your Own Card Has Been Cloned

If you landed here because unfamiliar charges appeared on your statement, the response path is well-defined. Federal law caps your liability for unauthorized credit card charges at $50, and the burden of proof falls on the card issuer, not you, to show the conditions for that liability have been met.3Office of the Law Revision Counsel. 15 U.S. Code 1643 – Liability of Holder of Credit Card Most major issuers go further with zero-liability policies that waive even that $50. Once you notify the issuer, you are not responsible for any charges that follow.

Call the issuer immediately by phone to freeze the account, then follow up in writing. The written dispute must reach the issuer within 60 days of the first statement showing the fraudulent charge. The issuer then has 30 days to acknowledge it and 90 days to resolve the investigation. While the dispute is open, you can withhold payment on the contested amount without penalty.4Federal Trade Commission. Using Credit Cards and Disputing Charges File a report at IdentityTheft.gov, and consider a police report if the fraud is part of a larger pattern. Those records matter if the case escalates or if other accounts of yours turn out to be compromised too.
