For a while I ignored TWINT, but eventually installed it as I found it useful to be able to pay for stuff when I forgot my wallet. Which actually increased the amount of times I left my wallet at home.
Do you have TWINT?
No mobile phone so no, I don’t. 
Nice. I’ve been using an old Nokia for many years, still going strong. But having a smartphone became a participation ticket for everything.
Almost exclusively for parking - no more hunting for coins.
I resisted getting it when it was first introduced as I didn’t see much point to it but I’ve had it a few years now and use it all the time.
As others have said it’s a godsend for paying for parking and it’s useful for sending money to friends etc.
Still no need for TWINT
Great for parking.
If you sell things at a market/crafts fair you can also create TWINT QR stickers for each item.
It’s been great for unmanned (and manned) farm shops too as they just need a QR code to be scanned.
Our recycling also uses TWINT. Weigh your stuff and then pay according to the weight.
Excellent also for paying for/selling second hand items rather than cash.
Like PayPal though, they take a cut from the seller.
I use TWINT as much as possible for CH-based internet shopping, especially for galaxus, as I can choose within the TWINT app from what account I pay (VIsa, personal account, or joint account).
OH had it for a bit but didn’t really like it.
The Twint UBS app just stopped supporting Neon cards which is sad. The Twint prepaid app isn’t great.
why? Aren’t all the Twint apps the same? I was thinking about getting Twint, I haven’t got it yet because perhaps I don’t need it 
, but my choice would be the prepaid to limit the clutter on the bank account. With Revolut I transfer some pocket money per month so my bank account has just 1 transaction per month
I forgot - the other bit of usefulness is sharing costs amongst friends. I prefund group squash sessions, the others mostly now refund me by twint. In the old days I used to have to handle a couple of Kg in coins all the time!
I hope not. UBS updated the TWINT app and made it terrible. I’m trying to find an alternative.
I use it to take payment for extras like pet cleaning charges and tourist tax which are not included in the base rental price. Really convenient, but only for Swiss guests. It’s about time the various phone payment systems in other countries were made compatible with each other.
Edit: otherwise it’s mostly cash, generally not large amounts, but I do occasionally get someone wanting to use a credit card, which is a right PITA as I have to create a payment request in my booking system and send it to them.
Yes. But I mainly use Apple Pay in shops. I use Twint to send and receive money from friends.
Can recommend plastic. Been using it for decades. Even since the 19 hundreds! And it also works outside of CH!
That’s true, I can squash a CC in my phone case.
yes, that’s why Revolut/Wise covers all my needs. There are also Swiss “app only” banking options with CC if someone wants to stay with local providers.
Each bank has its own Twint mobile app, there are over a dozen Twint apps:
