Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

:key: JavaScript class to control MFRC522 RFID Module with your Raspberry-pi

MFRC522 is integrated in all types of 13.56MHz RFID passive contactless communication methods and protocols.

It uses the ISO14443 specification to communicate to MIFARE cards (also known as NTAG, NFC) MIFARE wiki ISO14443 wiki

Features

  • Read uid & card memory
  • Write card memory & card key
  • Buzzer notification (Optional)

Demo

Example

Watch on Youtube (with sound)

Enable SPI

The SPI master driver is disabled by default on Raspbian. To enable it, use raspi-config, or ensure the line dtparam=spi=on isn't commented out in /boot/config.txt. When it is enabled then reboot your pi. If the SPI driver was loaded, you should see the device /dev/spidev0.0

more info about SPI

Install

npm version

npm install @efesoroglu/mfrc522-rpi

node-rpio Compatibility

  • Raspberry Pi Models: A, B (revisions 1.0 and 2.0), A+, B+, 2, 3, 3+, 3 A+, 4, Compute Module 3, Zero.
  • Node.js Versions: 0.8, 0.10, 0.12, 4, 5, 6, 7, 8, 9, 10, 11, 12

Card Register

Your MiFare NFC chip consists of multiple sectors, each containing 4 blocks. The first 3 blocks of every sector are used to store data, the last block contains security features (access keys and bits). Every block holds 16 bytes of data. A typical MiFare Classic 1K chip has 16 of these sectors, accounting to 64 blocks with 1024 bytes in total.

The first sector is reserved for manufacturer data, while the second sector is supposed to contain card holder data. So, to be on the safe side, start writing your data on the third sector, starting with block 8.

Every last block of a sector is called a trailer block. It contains two access keys, which are used for protecting the data against unpermitted access, and access bits controlling what can be done with this sector. The first 6 bytes of such a block contain access key A, the following 4 bytes are the access bits, and the last 6 bytes are access key B (optional key).

Please note that when reading a trailer block with this module, it will always return the same (incorrect) values regardless of its actual content. This might be a security feature of the chips.

For simplicity reasons, this module will always authenticate with and refer to key A only. The default key A on new cards is always [0xff, 0xff, 0xff, 0xff, 0xff, 0xff].

The access bits in the middle of a sector trailer block should never be changed without exactly knowing what you're doing. They control what can be done with the current sector and which of the access key(s) can be used for authentication. If they don't make sense, the sector (4 blocks) is irreversively blocked and can never be used again.

If you want to safely change the access key for a sector, please use the writeAuthenticationKey method (see the writeAuthenticationKey.js example in test). Always store the new access key(s) somewhere safe.

Changing Authentication Keys

This has so far only been tested with MiFare Classic 1K cards (the ones that come with the reader)! Please use the writeAuthenticationKey method (see the writeAuthenticationKey.js example in test).

Which hardware is used?

List of hardware which are used with links to amazon.de:

Buzzer Notifications (optional)

It's possible to get buzzer notifications when the module reads a chip, simply connect a piezo speaker to your PI.

Components for Buzzer

Those three optional component are required to run the buzzer with 5V. The RC522 is running at 3.3V so we need to step down the voltage a bit.
