> Now, increasingly, cellphones are *day-to-day life*. Far from the literal “pocket telephones” envisioned a century ago, they’ve worked their way into nearly every aspect of human existence, including those Haselden could never have considered.

It is now essential to be considered part of the society, to the point that someone who does not want to or cannot carry a cell phone is sneered at. Anecdotally, I was in the USA and during a few day lay-over, I wanted to get a hair cut. I was refused service at a hair cutting chain because I did not have a cell phone with me (it was in the hotel, did not want spam, would not get there and back on time, etc.). I offered credit card or cash, but was rejected, and explicitly told I have to have cell phone.

I am not angry, just sad.

As @nonrandomstring noted, "absurdity of reality is escaping parody".

Wow, that's a new one for me (only app payments accepted). In the US, at least.

I haven't encountered that yet, but I'm starting to encounter mobile apps as required proof of membership for things. My family got a membership to a children's museum a few weeks ago, and the expectation is that my wife and I have their app on our phones to get inside. For our second visit, I brought our printed receipt, but my wife had to stand there downloading and installing their app so that we could use our guest passes. The person at the front desk didn't seem to have any other way to do it. Similarly, my neighborhood's community pool and fitness center requires the Brivo Mobile Pass app to get through the front door (and it's unattended, so there's nobody who can just look you up in the system and let you in).

I think the worst part of this is businesses that do this all have different crappy apps. My gym has their own app that must be scanned upon entry. But their app is often slow and unresponsive, and unpredictably logs out. Often at the entry, a person will be stuck trying to reload the app, possibly hindered by their phone having switched to the gym's questionable wifi. Multiple other people will be stuck behind them, having preemptively loaded the app and QR code while walking to the door.

This replaced keychain fobs with a barcode, which had none of these annoyances.

> businesses that do this all have different crappy apps.

I want "app containers" on my phone to limit these apps and feed them fake data as needed.

On Android you should be able to create new user accounts on the phone which are completely separated and can be quickly switched between. I used to create one with just WhatsApp installed for instance.

Alternatively if you are rooted Xprivacy[0] does what you asked, allowing you to grant apps permissions but then feeding them fake data as configured.

No idea about iOS though.

EDIT: There seems to be an app called Insular[1] which also works like Xprivacy, but doesn't require root at all and comes with a couple of extra features like the ability to have multiple instances of an app installed. Haven't tried this one though and I have no idea if it even runs on newer versions of Android.
