ICODE®SLIX Reader What is ICODE®SLIX reader ?

The NXP ICODE® SLIX RFID reader-writer is equipped with a USB 2.0 interface that can be easily connected to any network and can be used with the most common ISO 15693 chips on the market. These are ICODE® 1, ICODE® SLI, ICODE® SLI-L, ICODE® SLI-S, ICODE® ILT, ICODE® ILT-M, ICODE® SLIX, ICODE® SLIX2, ICODE® SLIX-L, ICODE® SLIX-S are from the same ICODE® family of chips. They are both manufactured by NXP.

The ICODE SLIX is part of NXP's ICODE family of chips. The ICODE®series is older than NXP's NTAG series and has a number of significant differences - particularly a longer 8 byte UID and a longer memory retention specification of 50 years. However, this ICODE® SLIX2 variant is newer and contains a large number of feature enhancements.

The I ICODE® SLIX reader working voltage is DC 5V and it is a cost-efficient USB interface plug and play RFID reader with integrated Keyboard Emulation (KEMU). It supports reading multiple tags at one scan for the anti-collision algorithm.

ISO 15693 Standard

The standard for vicinity tags is ISO 15693. The ISO 15693 tags must operate at 13.56 MHz and have a maximum read distance of 1 meter, according to this standard (3.3 ft.). For uniform implementation, ISO/IEC 15693 also regulates the power and communications between the cord and the reading device. Aside from that, the standard specifies the physical size of cards as well as card and reader commands.

ISO 15693 differs from the NFC standard in that it provides for a read range larger than 10 cm. The NFC specification does, however, enable ISO 15693 tags that are structured in the NDEF format. Furthermore, many (but not all) NFC-enabled devices can communicate with ISO 15693 tags that aren't NDEF compliant. For ISO 15693 tags and NFC tags, there are various separate standards that describe the modulation type, maximum read distance, and data rate of the tags. In addition, the standards will usually include a list of acceptable standard commands to guarantee that compliant ISO 15693 readers and ISO 15693 tags work together.

What Is the Difference Between ISO 15693 and ISO 14443A ?

ISO 14443A tags are designed for financial transactions. The read distance is supposed to be very short—a few inches—to protect against someone intercepting data sent from a tag to a reader. As a result, such tags aren't appropriate for tracking library books. They could operate with a desktop PAD reader, but the short read range would be a disadvantage if you wanted to install security gates at entrances or allow workers to inventory products.

The ISO 15683 standard was created for access control, and tags that comply with it have a read range of up to three feet (0.9 meters). For inventory control, such tags became common in libraries and other applications. It would be better for tracking books at a library because of the longer read range.
