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.

Near Field Communication (NFC)contactless cards can be a wireless communication standard which helps two devices within a short range to ascertain a communication channel in a short time through radio waves from the 13.56 MHz frequency range. NFC can be a useful technology for data between two devices near one other. As it needs both the devices to get near the other person (lower than 10 cm), it is more secure thanother wireless technologies like Bluetooth and Wi-Fi. Hence, it could be described as simple and easy , secure tool for establishing quick two-way connections for data. As the biggest differentiating factor for NFC over RFID is that it's a two-way communication tool, one of many devices/cards could have a passive NFC tag which could decrease the cost but still behave in the same manner every other RFID tag.
