3 Basic Things to Know About Passive UHF RFID Tags [Video]
Can u tell me how hex code stored in the IC chip of the RFID Tag is transferred through the Antenna to the RFID Reader.
This is actually a very complex process, but, in short, here is how it works with passive RFID tags:
The reader (through its antenna) sends a radio signal to the tag, which acts to "energize" the tag. Once the tag is activated, it reflects back to...

DIY FSK RFID Reader
This page describes the construction of an RFID reader using only an Arduino (Nano 3.0 was tested, but others may work), a hand-wound wire coil, and some assorted low cost common components.
The hardware and software designs for this project are based in part on the ideas, code and schematics posted by Micah Dowty here and Asher Glick here...
OpenBeacon active RFID tags with Arduino, do they compatible?
Here is the tag. it uses nRF24L01 chip:
Here is the USB receiver:
Here is a guy reviewed these devices few years ago:
My guess is that the receiver output is serial and it is then converted to USB using serial to USB chip. I asked Amal, the guy who...

Practical Arduino: RFID Access Control System
RFID Access Control System
RFID technology is used for a wide variety of applications including access control, package identification, warehouse stock control, point of sale scanning, retail anti-theft systems, toll-road passes, surgical instrument inventory, and even identifying individual sheets of paper placed on a desk. RFID tags are embedded in name badges, shipping labels, library books, product tags and boxes, installed in aircraft, hidden inside car keys, and implanted under the skin of animals or even people....
Arduino HF/UHF RFID Reader
I'm looking for a HF/UHF RFID reader I can interface with via Arduino. I've been using 125kHz solutions which, though they work great, just don't have the range I'd like them to.
Ideally, I'd like an RFID reader that can pick up a passive RFID tag that is in a wallet/pocket and within 1-2m, without the user having to present the tag to...

Arduino RFID Reader RC522 + Access Control System
SS (or SDA) -> pin 10
RST -> pin 9
3.3V -> 3.3V
GND -> GND
The resetAlarm integer is the Arduino pin where we connect the button that is used the reset the alarm. The relay is connected to pin 7 and the active buzzer to pin 8.
On the next lines you need to change the cards codes with the ones you have. You'll have to read the codes in the serial monitor then decide which ones you want to use to allow access in your room (watch the video to see how I've made it). You can use only one card or as many as you want, but add the comma after each array of...

One of the things that I love is hardware with beautiful housing. So I attempted to create a wooden housing based on examples of ornately decorated objects that I found. I'm going to be looking at this every day, so I wanted it to be pleasant and not as impersonal as so much technology feels.
