I wanted to build a device to track the stuff I have in my bag. I wanted to use passive RFID tags which I would place on my objects.
The problem now is that I don't have much experience with RFID and I am not sure how well certain tags can be detected. I've researched a bit and found out that UHF tags are very good for tracking multiple things, but also that they don't penetrate materials as good as lower frequency chips. Do you think a 850 - 960 MHz chip would be readable if it is placed inside a thick book like a novel?
