Thank you for your question. I am one of the 22 Primary Investigators for the U.S. FDA trials and am now in the 6th year of follow up visits for my patients, so I've got a lot of experience with Motiva implants and the Q chip. The device itself is simply an optional, passive RFID chip that is encoded with a 15-digit number that means nothing to anyone except the manufacturer. Before placing the implant, the number is recorded and sent to the manufacturer. After surgery, a physician with the correct device can read the implant's number, call the manufacturer (with your consent), and find out what implant you have, who implanted it, and when. In short, it is a redundant source of information in case you lose the implant information card and can't get the information from your surgeon. I firmly support and recommend the technology, and my patients tended to opt in. In my group of patients, nearly 80% chose the Q Inside chip. (In contrast, only 30% of the patients in the study overall chose the Q.) I don't see much downside, while the upside is obvious. It is MRI compatible, carries no actual patient information, and is a device with it's own FDA approval. Speak to your surgeon if you have any questions, but I'm a fan of the technology.
