The ICODE SLIX IC (SL2S2002, SL2S2102) is a dedicated chip for intelligent label applications such as libraries, product authentication in different industries such as pharmaceutical, medical devices and alcohol, as well as production management in different areas of the industry. This IC is the third generation of a product family of smart label ICs based on the ISO standards
ISO/IEC 15693 and ISO/IEC 18000-3 , prolonging a successful story of NXP in the field of vicinity identification systems.
The ICODE system offers the possibility of operating labels simultaneously in the field of the reader antenna (anticollision). It is designed for long range applications.
1.1 Contactless energy and data transfer
Whenever connected to a very simple and easy-to-produce type of antenna (as a result of the 13.56 MHz carrier frequency) made out of a few windings printed, winded, etched or punched coil, the ICODE SLIX IC can be operated without line of sight up to a distance of 1.5 m (gate width). No battery is needed. When the smart label is positioned in the field of an interrogator antenna, the high speed RF communication interface enables data to be transmitted up to 53 kbit/s.
1.2 Anticollision
An intelligent anticollision function enables several tags to operate in the field simultaneously. The anticollision algorithm selects each tag individually and ensures that the execution of a transaction with a selected tag is performed correctly without data corruption resulting from other tags in the field.
1.3 Security and privacy aspects
• Unique IDentifier (UID):
The UID cannot be altered and guarantees the uniqueness of each label.
• Password protected EAS and AFI functionality:
The 32-bit EAS/AFI password enables the addressed label to be set in a mode where the EAS status and the AFI value can only be changed if the correct EAS/AFI password is transmitted to the label within the mentioned commands.

As a mifare ultralight credit holder has its advantages and its setbacks. If you have good credit, you will find the financial credibility that allows you to make financial transactions far more smoothly. Just carry a card all day long instead of bother about dropping any dollar bills or change. It is possible to breeze though any purchase in a swipe. However, developing a personal credit line also makes you at risk of transforming into a victim of identity fraud.
