At the moment there is a problem writing NDEF data to the xSIID. The NTAG I2C chip used in the SIID module has 2kB of memory, split into two large memory sectors. The problem is that the NTAG I2C chip is not commonly used by consumers, and at the moment there are no apps available that properly identify and write to the entire user memory. Smaller data sets which remain within the 1kB range (the first memory sector) tend to succeed, however larger data which must extend into the second memory sector will fail. We are working with NXP now to fix bugs in their TagWriter application to ensure at least TagWriter will be able to properly write data to all 2kB user memory. Other options such as NFC Tools also exhibit bugs and other issues attempting to write data, particularly large NDEF records.

xSIID Kit Contents

The xSIID kit contains the following products and materials, which are designed to enable you to bring the kit to a professional installation partner for installation.

• 1 sterile injector assembly, pre-loaded with xSIID chip implant
• 2 single use ChloraPrep antiseptic wipes
• 1 sterile gauze pad for post-installation wound care

xSIID Kit Extras

The following accessories also come with the xSIID Kit. These accessories are “field detection” tools designed to assist you with identifying the type of readers you may encounter, but also the best location and orientation to present your xSIID chip implant to any reader to get reliable performance.

• 1 RFID Diagnostic Card
• 1 13.56MHz X Field Detector

Our X Field Detectors (XFD) will show you the best position and orientation to present your chip implant to any readers of the same frequency, while our RFID Diagnostic Card will tell you all about the frequency and duty cycles of random readers you encounter in the wild.
