UFR Reader Raspberry Pi Shield - Shell-Bash

The UFR Reader Raspberry Pi Shield allows developers to easily integrate NFC and RFID functionality into their Raspberry Pi projects. With this shield, you can read and write to RFID tags, as well as communicate with NFC-enabled devices.

Features

• Reads and writes to 13.56 MHz RFID tags
• Communicates with NFC-enabled devices
• Simple, easy-to-use interface with shell-bash programming
• Open-source libraries available

Getting Started

To use the UFR Reader Raspberry Pi Shield with shell-bash programming, you'll need to install the necessary libraries and drivers. You can find instructions on the manufacturer's website.

Once you have everything set up, you can start reading and writing to tags with just a few lines of code. Here's a simple example:

#!/bin/bash
# Import the UFR Reader library
source ./ufr-lib.sh

# Initialize the reader
ufr_init

# Wait for a tag to be detected
ufr_wait_for_card_present

# Read the data from the tag
tag_data=$(ufr_read_data)

# Print the data to the terminal
echo $tag_data

# Deinitialize the reader
ufr_deinit

This script initializes the reader, waits for a tag to be detected, reads the data from the tag, prints the data to the terminal, and then deinitializes the reader.

Conclusion

The UFR Reader Raspberry Pi Shield is a powerful tool for adding NFC and RFID functionality to your Raspberry Pi projects. With simple and easy-to-use shell-bash programming, developers can quickly create applications that read and write to tags, and communicate with NFC-enabled devices. Whether you're building an access control system, inventory management system, or anything in between, this shield can help you get there faster.
