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 Playground - DIYRFIDReader

Documentation index


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...

3 Basic Things to Know About Passive UHF RFID Tags [Video]

shrey Tyagi


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...

Arduino RFID Reader RC522 + Access Control System

SS (or SDA) -> pin 10

RST -> pin 9

3.3V -> 3.3V


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...

RFID front door lock -

More photos in the� RFID front door photoset .

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.

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....

RFID Reader + Ethernet Shield - Arduino Forum

Quote from: mnoeth93 on Apr 07, 2014, 06:34 pm

I found the following qoute from wiznet: "One difference between other SPI slave devices compared to the W5100 is that the MISO output is continuously driven in the W5100 whether the /SCS is asserted as high or as low".

So it doesn't matter what Signal to put on the chip select the MISO will be active the...
