What is chip in smart card?

A standard size plastic debit or credit card which consists of an embedded microchip including magnetic stripe.
This chip encrypts all security data during transactions at different places stores, terminals, or automated teller machines (ATMs).

A chip in a smart card refers to the integrated circuit embedded within the card. This small microchip is capable of storing and processing data. Smart cards come in various forms, including credit cards, identification cards, access cards, and more, and the embedded chip distinguishes them from traditional magnetic stripe cards.

The chip in a smart card can store and process information securely. It can hold various types of data, including:

  • Personal information: Such as the cardholder’s name, ID number, and other pertinent details.
  • Authentication data: Used for secure access control, like PINs or biometric templates.
  • Cryptographic keys: Utilized for secure transactions or authentication processes.
  • Application data: Specific information related to the card’s purpose, like loyalty points, financial data, or access permissions.

The chip interacts with card readers through electrical contacts or contactless radio frequency (RFID) technology. Contact-based smart cards require physical contact with a reader for communication, while contactless cards can communicate wirelessly when in proximity to a compatible reader.

These chips provide enhanced security and functionality compared to traditional magnetic stripe cards, as the data stored within the chip is harder to duplicate or tamper with, making smart cards valuable in various industries for secure transactions, access control, and identity verification.
