How do i use this without arduino?
Is there any way to disable the beeping sound?
Yes, please see the hardware overview section of the guide for directions on how to do that.
Using Node.js to read from the reading using node-serialport. Getting reading coming in but my numbers don't match what is on the card. I assume this is something to do with encoding but I'm not sure. Anyone able to help me? I scan a card with the printed numbers "0000818960" and I get "0A000C7F1069" when I do "data.toString('ascii')" on the data coming from node-serial port. Thoughts?

Read Ranges Using the RFID USB Reader
Using the ID Innovations125kHz readers, the tested real world maximum ranges of the modules with the RFID tagged items are listed below:
Card = 0" (you need an external antenna)
Button = 0" (you need an external antenna)
Glass Capsule = 0" (you need an external antenna)
Card = 2" - 2.25"
Button = 1" - 1.5"
Glass Capsule = 0.75" - 1"
Card = 2.75"
Button = 2"
Glass Capsule = 0.75"
The range results were taken from the demo video between 6:13-9:10 => https://youtu.be/FLjV5BT9slg?t=6m13s .
Multiple RFID USB Readers
If you place 4 of these RFID readers with the ID Readers, there will be RF interference from each other. Customer had issues with this setup. When he placed them at a distance of about 15-20cm+ between each other, they were able to get them working.
I've been having issues with my RFID. I'm not sure if it's in the wiring, the code, or just a bad component, but I was hoping for some advice.
I've used your code, as well as 4 others that I found on google, each of which returned the serial values "255 255 255 255...", so I kind of doubt its the code. (I should mention I put in a Serial.print(readByte) in the loop to see what the integer values were)
It is hooked up as follows:
Lastly, I assume the components work fine, because it never returns any serial values to my com port until I wave the tag in front of it.
The code example does not work correctly.
total = checkTag(newTag, knownTags[ct]);
total += checkTag(newTag, knownTags[ct]);
Otherwise only the last card in the array will ever work.
Thanks for this- will get the code updated
do i need to use arduino with RFID reader starter kit to save tags ID ?
You don't have to use an Arduino, but you do need something on the other end to capture and save the data. You could do it with a PC over USB, or use the serial output or the USB output with a Raspberry Pi or another single-board computer.
