These NFC Type 5 key fobs are different than other NFC key fobs because they contain the ICODE® SLIX chip
which support the different NFC protocols, the ISO/IEC 15693 and ISO/IEC 18000-3 protocols.
They are interesting because the reading distance for these kind of chips can be from couple of centimeters to 1.5 meters. Actually, we were able to read the chips at a distance of max 10 cm, but we were using just a regular desktop reader for ISO 15693 and for achieving greater distances you have to ask for more information some specialized equipment manufacturer.
Our readers that work with ICODE SLIX chips are the SYRIS RD300-H1-G readers
The other interesting ICODE SLIX chip feature is that it has 1 kB of memory and when you store your product manufacturing information it will be there for up to 50 years. The common NFC Type 2 chips have a smaller memory size and data retention time of just 10 years.
The 8-bytes long factory pre-programmed ID number is commonly used for product or user authentication and production management in different industries.
Reading test for flexible 25 mm-sized NFC stickers with an ICODE SLIX chip and on-metal protection
Various transponders even containing the same kind of chip achieve different reading distances because they have different size, types, and quality of antennas.
The other factors affecting the reading distance are the strength of the reader signal, the electromagnetic interferences from the environment, the proximity of metallic components, etc.
We tested these stickers with different kinds of readers and measured the reading distances. This is not an official test, but was made to inform you about what reading distances you may expect with your application.
An NFC mobile phone can read the ICODE SLIX chips, but the programming is usually not supported.
