Communication with a new RFID-Reader:

"Hello RFID-Reader" - "何?"

Okay: "ハローリーダー" - "¿Qué?"

Seriously? "Hola lector RFID" - "Что?"

Wait a minute...
[puts wire into *correct* port of the development system]

"Hello RFID Reader" - "Hello"

It's been a long day and the brain is obviously the first thing to go to sleep... even when you're still awake.

What do you think about my custom doorsystem? It's build with a pi, RFID reader, touchscreen and some other parts. (It's still in development)

Hey guys, my gf and I want to do something with the Arduino we got. We are getting a CS degree, so programming is not a problem, but we have quite basic knowledge of electronics.

What could be a cool simple (but not too introductory) project we could do?

The arduino came with a bunch of sensors (ultrasonic distance sensor, humidity, ...) some input (joystick, RFID reader/writer, buttons) and some outputs (LCD display, 8x8 LED matrix, bunch of color and RGB leds).

Got my RC522 RFID reader for a school project last night, got it to work, tried to plug it into my breadboard this morning and shorted it... Double checked on 2 different arduinos and 1RPi 3 B didn't work on either one of them.

Fuck my life.

!rant, story

Wonder if I’m alone on this:
I have habits.
Always use the same cup, with very same amount of coffee grounds. Same four presses with the same fingers on the coffee machine.
Same way I place the cups in my desk. Same way I carry my notebook, same way I dry my hands. Same exact spot I place my card on the rfid reader. Use same elevator, same locker. God.
You name it, I do it on my own particular way.

Thing is, that I think about it. I do it consciously. I am just happier if things stay the way they are. It not just muscle memory thing.

Not judging here, just wonder if there’s people who can relate as much 🧐

So I’ve asked my Unis infrastructure guys via mail, why we don’t use the digital id with our phone additional to our RFID Badge.

One of those (maybe a moron, I don’t judge yet, see question below) replies, that they would need to replace all readers “as current ones rely on RFID scanning chips” and they are not sure how US Unis implemented it.

Thing is, that when I hold my iPhone SE 2020 next to the reader, my phone shows my credit card to use for Apple Pay.
Doesn’t that mean, that they use compatible RFID frequencies ?
I’m not an iOS dev, so maybe someone can help me out. Any info appreciated!

It's been awhile, for the heads up I'm that good dude applied a job as MIS few months ago, knows a little bit python and the manager finds out, he told me I gotta make a Warehouse Management Software for the company in C# PLUS MIS regular work(server management, user trouble-shooting and stuff).

after I finish my Warehouse Management Software about a week ago, my manager told me which I quote:

"wpf is not enough! we gonna bring it to multi platform like a web interface can be use on employee's phone as barcode reader and do things can be done as wpf can.

aaaaand we need RFID integration for the whole system working with Identity Server on Azure.

AAAAAAND we need it online before Feb 2020."

I guess after C#,
I'm learning typescript and angular now.

oh by the way my position is MIS with MIS salary.
Does this means after all these shits. I can apply as RD my next job right?

I want to do one project in which using arduino uno and RFID reader to take attendance but for this I have to need 100 reader card which is costly. So I thought using bar code so I can print barcode on paper and no need any card. So does anyone idea where I can get bar code module for arduino uno.

Hey people!

I need your brains!

I have this project, maybe you can help me with some ideea on how to implement it.

So, I need to read a lot of rfids. A lot. 100+ (It should work with any number of readers).
Next to the reader should be some leds to indicate a status.

Think of it as a matrix or readers. it should support x * y rows / columns

So, let's call it a node (the reader plus the leds).

Now, I have no ideea on how to link all those nodes to a raspberry pi.

For few it would be kinda easy, but when it goes to 100, I don't really know how to link all those together.

I was thinking about a cheap arduino to read the rfid and deal with the leds.

But I don't know how to link (in a bidirectional method) 100 arduinos to a rpi.

So, if you have any ideeas, that would be great.

Thanks!
