Not sure what other information you might have. But I've worked with various RFID systems. These types of systems do not contain personal information. They are extremely simplistic and contain ID codes. All such systems require connecting to a database to retrieve the information they need based on the code. To some, that gives the impression that they have your personal information on them, but they don't. The personal information is in the database. The RFID device is the key. You need to have access to both.
But I have to again agree to disagree with you regarding the MagicBands and personal information.
