The white plastic card with integrated chip card module from manufacturer ESEN, type JT-217, is a consumable for POS systems and other applications requiring contact-based data transmission. The card features a 2KBit memory, enabling a capacity of 256 characters. It is manufactured in accordance with the ISO7816 standard, ensuring compatibility with standard chip card readers. The cards are available in a pack of 100 and are intended for use in retail, service companies, or other environments where secure and reliable data transmission via contact-based interfaces is required.

Chip card
The integrated chip card enables data storage and transmission via a contact-based interface. The memory capacity of 2KBit corresponds to a maximum of 256 characters, sufficient for basic identification data, transaction information, or access rights. The card is designed for use in systems supporting the ISO7816 standard, which is globally established for contact-based smart cards. This standard defines the physical and electrical requirements for the cards as well as the communication protocols, ensuring compatibility with a wide range of readers.

Applications
The card is primarily intended for use in Point-of-Sale systems (POS), where it can serve as an identification or transaction medium. It is also suitable for access control systems requiring contact-based authentication. Its use in standard chip card readers makes it universally applicable across various industries, particularly in retail, the service sector, or administrative environments where simple and robust data transmission is necessary.

Functions and equipment in detail
The card consists of a white plastic carrier with an embedded chip module. The module supports the ISO7816 interface, enabling electrical connection via contacts. The 2KBit memory capacity is sufficient for most applications, especially when the data structure is simple. The card is not designed for storing large data volumes or complex applications, but for use in systems requiring fast and reliable data transmission with minimal memory requirements.

Technology explained simply
The ISO7816 standard defines the physical and electrical properties of contact-based smart cards. The card features contacts that connect with a corresponding reader to exchange data. Communication occurs via a serial interface, with the card acting as a passive device powered by the reader. The 2KBit memory size corresponds to approximately 256 characters, sufficient to store, for example, a username, ID number, or transaction reference.

Compatibility and accessories
The card is designed for use in standard chip card readers supporting the ISO7816 standard. This includes a wide range of readers used in POS systems, access control systems, or other applications. Compatibility is based solely on the card's conformity with the standard.

Mounting and installation
The card requires no mounting or installation. It is simply inserted into a compatible reader, ensuring the chip contacts connect with the reader's contacts. Correct orientation is essential to ensure successful communication. The card is designed for use in standard POS systems and other devices accepting contact-based smart cards.

Advantages in operation
The card offers a reliable and cost-effective solution for applications requiring contact-based data transmission. Compatibility with standard readers reduces system integration complexity. The 256-character memory capacity is sufficient for many standard applications, and the robust design ensures long service life under normal operating conditions. The packaging of 100 units enables economical procurement for businesses requiring a larger quantity of cards.
