Why it is called an integrated circuit card
ICC stands for Integrated Circuit Card. The name describes the electronic circuit, or chip, built into the card. In payment technology, ICC appears in technical materials about chip-card transactions and equipment.
You might see ICC in a payment terminal manual, setup screen, or card-acceptance specification. The label tells you the card has a chip, but it does not identify whether the card communicates by contact or contactless, or whether it is used for payment, identification, or access. Those details matter when you check whether a reader supports the cards your business accepts.
ICC is a technical label for the same general type of card called a smart card. The rest of this page explains smart cards and what they mean for your business.
What a smart card is
A smart card is a physical card with an embedded chip that stores data or processes information. A reader connects with the chip through electrical contacts or a wireless signal. Smart cards are used for payment cards, employee IDs, transit fares, health insurance cards and access credentials.
The term describes a broad technology, not one payment method. A transit card or building-access card can be a smart card without being a payment card. EMV (Chip Card) is a payment-card standard that uses chip technology, so it is one specific use of smart cards, not a synonym for every smart card.
A smart card describes the chip, not a special processing fee or a guarantee against fraud.
How smart cards work
With a contact card, you insert the card into a compatible reader. With a contactless card, the reader communicates wirelessly with the chip. A dual-interface card supports both methods. The reader passes information to the system that checks the card and decides what action to take, such as approving a payment or granting access.
Smart cards include memory-chip cards and microprocessor cards. A memory chip stores data, while a microprocessor can process information and support programmed functions. The card, reader and connected system must be compatible; a chip card that a reader cannot read can slow checkout or require another payment method.
What smart cards mean for payment costs
For a US merchant, accepting a smart-card payment requires a terminal or reader that supports the card's contact or contactless method. If you replace equipment or add a card-based access system, that hardware and setup can add operating costs. There is no single smart-card fee or standard statement line identified by the term itself.
A smart card does not remove the usual components of card-processing costs. For a payment card, your costs still depend on the card transaction and its processing, not simply on the fact that it contains a chip. Chip technology can reduce reliance on static magnetic-stripe data, but it does not prevent every fraud attempt or remove the need to monitor transactions.
What you can actually change
You control whether your equipment and procedures support the smart cards you accept. Before deployment, test the card, reader and connected system together, including what staff should do when a read fails.
- Confirm your payment terminal accepts the contact or contactless chip cards your customers use.
- Test card reads at checkout and train staff on the fallback process for failed reads.
- For ID or access cards, limit access to the data and functions each card needs.
- Review your statement's actual processing and equipment charges instead of treating smart card as a fee category.
- Test your readers. Run contact and contactless cards through your equipment before relying on them at checkout.
- Train for read failures. Give staff a clear next step when a chip cannot be read, so customers are not left waiting.
- Separate real charges. Compare card-processing and equipment charges on your statement without assuming smart card is a fee line.
Frequently asked questions
Is an Integrated Circuit Card the same as a smart card?
Yes. Integrated Circuit Card describes a card with a built-in chip, and smart card is the broader, more familiar name for that card type. The terms do not identify a separate processing fee.
Does ICC mean a payment card?
No. An ICC can be used for payment, identification, access, or other data tasks. In a payment terminal manual, the surrounding instructions tell you whether the reference is specifically about chip-card payments.
Does ICC tell me whether my terminal accepts contactless cards?
No. ICC identifies the card's integrated chip, not its communication method. Check your terminal's specifications for support for contact, contactless, or both.
