I hate how everything requires you to download a shitty proprietary data harvesting app nowadays when everything can be done just fine without an app.
I have recently started a new position and am required to use an app that has three Facebook trackers, one of them being a Facebook location tracker according to Exodus App Privacy in order to get your food when it would literally work perfectly fine ordering to a real cashier or shit even a website rather than having to download an app.
I have also read many stories of people that live in apartments that require them to use a mobile app for god damn LAUNDRY. All you need, is a card reader, and it will work perfectly fine like it has been for the longest time.
Privacy concerns aside, it is just annoying that you need this app and that app and this app and that app and it just clutters space on your phone. Security concerns too as now they have all of this additional info on you online, such as your phone number your email your real name, instead of just your credit card info like a card reader would have. And I am willing to guarantee that their security model is absolute horseshit because they have such a small team of engineers working on the app and the servers.
I work on the enterprise apps team at my university. We'd dump that so hard you'd think we were using it to get liftoff. Definitely complain. Also, it's not inclusive to students without smart devices (they exist!).
If they do still have the option for manual use (with ID card scanners), there are a number of membership card / ID card wallets that are free on most platforms. You can just type the barcode into the app, and it'll make a virtual card that can be scanned. Same convenience, no physical plastic. If you're not offended by Google products, Google Wallet works pretty well. Or Stocard, but I'm not sure what level of tracking they implement. Granted, you're still installing an app, but you get to pick your poison a bit, instead of being railroaded into Facebook shenanigans.
