I feel that barcodes (usually QR Codes) are underutilized; I forgot about them until I saw this post.

  • I think barcodes could potentially be used to quickly transmit preset information to war victims.

  • They could be used to transmit information on platforms that censor: Sharing Lemmy posts on Reddit (even though it’s currently redundant due to federation). (I just thought of this.)

I once saw a demonstration when qr codes were new where they actually made video qr codes. It was like a modem but with video instead of audio. I don’t recall the bitrate but it was high enough to be useful.

(It was used to demonstrate exfiltrating from an airgapped computer)
