An Arduino-powered NFC scanner can make a DVD case act like a launch button for a digital movie: a sticker on the case identifies a film stored on a laptop, and the computer starts playback when the case is scanned and an arcade button is pressed. The case is a physical controller, not a container for the movie or a device that reads a DVD.
How the movie-cartridge scanner works
In the build described by creator u/JackIrishJack, an NFC sticker attached to a DVD case carries an identifier. An NFC/RFID reader connected to an Arduino scans that tag and sends its code to a laptop. A Python script running on the laptop checks a text mapping file for the code, finds the corresponding movie folder on a hard drive, and plays the movie file inside it. The creator says playback proceeds only when the arcade button is pressed as well as the tag being scanned. Project discussion on Reddit.
Some tags can stand for genres rather than individual titles. The creator says scanning a genre case selects a random movie assigned to that genre. In either case, the sticker supplies a selection; the movie itself remains in the computer’s movie library.

The creator’s description confirms an Arduino, an NFC/RFID module, NFC stickers, a laptop, a hard drive with movie files, a 3D-printed housing, and an arcade button. The laptop runs the lookup and playback software; the Arduino acts as the scanner interface.
#1 Best Overall
- RFID reader/writer supports: Mifare 1k, 4k, Ultralight, and DesFire cards, ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX), Innovision Jewel cards such as IRT5001 card, FeliCa cards such as RCS_860 and RCS_854

- Support NFC RFID reading and writing, P2P communication with peers
- Support I2C, SPI and HSU (High Speed UART), easy to change among these modes
- Small Size and easy to embed into your project
The post does not identify the Arduino model, reader model, tag standard, wiring, media player, or a public source-code repository. The author says the Python script runs at startup and uses a text file to associate tag codes with movie-folder names, but does not publish a complete bill of materials or code in the discussion. Those details should not be inferred from other NFC projects.
What you need to build a similar setup
- A tag and compatible reader: The featured project uses NFC stickers and an NFC/RFID reader, but does not specify their standards or models. Check that the tags you buy are supported by the reader; “NFC” and “RFID” product labels alone do not establish compatibility.
- A controller and host: In this design, an Arduino reads the tag and a laptop runs the Python script. The computer also needs access to the movie files.
- A mapping and playback workflow: The script needs a way to match each scanned identifier to a movie folder or genre, then hand the selected file to a playback application.
- A physical interface: The creator’s setup uses an arcade button and a 3D housing. The post does not provide a downloadable enclosure file or specify how the button is wired.
Because the featured post omits exact parts and code, it is a concept and workflow reference rather than a step-by-step wiring guide. A builder would need to choose compatible components and implement the tag lookup and playback behavior for their own computer and media library.
Rank #2

- The module use a voltage of 3.3V, it can connected communication with user's any CPU mainboard through several lines of SPI interface, it can ensure stable and reliable work, and reader distance.
Other NFC movie-player approaches
NFC can trigger playback through different host arrangements. Two documented projects illustrate alternatives, but their components are not specifications for the Arduino build.
| Approach | Host and playback | Library arrangement | What the guide specifies |
|---|---|---|---|
| Arduino scanner described here | Arduino reads the tag; a laptop script handles lookup and playback | Movie files are on a hard drive connected to the laptop | The Reddit post does not specify exact controller, reader, tag type, wiring, media player, or public project files. Creator’s discussion |
| ESPHome and Home Assistant cartridge player | ESP32-S3 Zero reports the tag ID; Home Assistant runs the automation and media action | Media playback integrations include Plex on Android TV | The Stock Pot guide specifies an RC522 reader, 25 mm NFC stickers, ESPHome, Home Assistant, and its own 3D-printed housing and cartridges. The Stock Pot guide |
| Raspberry Pi player | Raspberry Pi 5 runs Python and VLC | Locally stored video files | Adafruit’s guide describes an NFC breakout and cards, a VHS-inspired case, and a script mapping cards to video files. Adafruit guide |
A laptop-based design keeps the reader and playback computer separate. An ESPHome/Home Assistant build puts tag reporting into a home-automation workflow, while the Raspberry Pi guide combines scanning and playback on a single-board computer. The right arrangement depends on where the library lives and whether you want to maintain a separate automation or media-server setup.

What “movie cartridge” means here
The cartridge metaphor describes the physical interaction: pick a case, scan it, and start the associated movie. It does not mean the DVD case contains the video, that the scanner reads a DVD, or that this project streams titles from a subscription service. In the featured build, the identifier points to a local movie file on a hard drive.
