CONTACT SMART CARDS

---

Contact smart cards are a type of integrated circuit card (ICC) that require physical contact with a reader to function. These cards are embedded with a microprocessor or memory chip, enabling them to store, process, and secure data. Widely used across various industries, contact smart cards are known for their reliability, security, and versatility. Below is a detailed introduction to contact smart cards, covering their features, applications, benefits, and manufacturing processes.

What Are Contact Smart Cards?

Contact smart cards are plastic cards, typically the size of a credit card (85.6 mm x 53.98 mm), that contain an embedded microchip. The chip is exposed on the card's surface through gold-plated contact pads, which must physically touch the reader's terminals to establish communication. These cards are compliant with the ISO/IEC 7816 standard, which defines their physical and electrical characteristics.

Key Features of Contact Smart Cards

1. Embedded Microchip:
   
   • Contains a microprocessor or memory chip for data storage and processing.
   • Supports encryption and secure data handling.

1. Contact Pads:
   
   • Gold-plated contact pads enable communication with the reader.
   • Typically, 6 or 8 contact pads are present, each serving a specific function (e.g., power supply, data transmission).

1. Memory Capacity:
   
   • Ranges from a few kilobytes to several megabytes, depending on the card type.
   • Suitable for storing personal data, cryptographic keys, and application-specific information.

1. Security Features:
