Choking can be an intense and exhilarating experience for some people. It can increase sexual arousal and pleasure by restricting blood flow to the brain, causing a rush of endorphins and a feeling of euphoria. Additionally, some people enjoy the feeling of domination or submission that comes with choking.
Also supports barcode scanning via https://github.com/Forceu/barcodebuddy, although I’m a bit confused… The official android app claims to support barcode scanning: https://github.com/patzly/grocy-android

You’re right, going for asphixation is more dangerous than many folks assume, especially since it has become quite normalized through porn. Most porn scenes and I assume most more vanilla folks at home don’t restrict blood flow, they just put their hands on the neck without much pressure for the feeling of domination.
If you still want to engage in actual breath play… There are good resources on the risks and different techniques of choking and breath play out there, don’t put actual pressure on a persons neck without informing yourself and talking about the risks. One variation is to instruct a person to hold their own breath once you touch their neck, so you still are only simulating a choke without actually putting pressure on the neck.
