Hi I am starting a project for book management in a library. The primary concern is I need to verify which book is being taken out and raise an alarm if the book being taken out is not issued. So I am planning to use some form of RFID (or NFC) tags for this. I have noticed that some of them come in…

Hi, @techiiieee Can I suggest you do some more research. Google; book rfid system arduino This might help to start; IJIRT147791_PAPER.pdf (648.0 KB) Can you please tell us your electronics, programming, arduino, hardware experience? Tom... :smiley: :+1: :coffee: :australia:

Thanks for help @TomGeorge [image] TomGeorge: Google; book rfid system arduino I have already tried this. What I'm getting mainly is how can we issue and return books using rfid. That's not my main problem. I can do that since I have already worked with mfrc522. They are low range (almost…

Well, the system in our local libraries just seem to have the standard tag labels in the books which are read at short range by the issuing terminals. There the sending antenna is quite a small coil, but a larger coil, possibly driven with more power, should have longer range. The ones at the egr…

[image] techiiieee: verify which book is being taken out and raise an alarm if the book being taken out is not issued. Have you rejected the commercially available systems, which have been around and in use in libraries for 1-2 decades?

[image] jhaine: The ones at the egress are about 1m wide, 1.8m high, there are at least two mounted parallel about 1.5m apart, either side of the pathway to the door. I assume that they work as "Helmholtz Coils" to create a fairly uniform magnetic field in the space between them to excite the ta…

[image] techiiieee: I am enthusiastic about electronics and arduino related projects and thus I want to build it myself even if gets a little technically complicated. You might be, but the only passive long range reader you will get is a UHF reader. That is a design job for a serious, profess…

[image] Grumpy_Mike: That is a design job for a serious, professional, licensed engineer. I don't intend to design a reader. I am just looking for a module or something similar that I can use with my arduino uno for this project. Thanks for help

[image] techiiieee: Can you please help me with which antenna I should use with this? The antenna is on the printed circuit board. See the tuning fork shaped trace on the end of the board?
