I've never written a check, but I have had to deposit occasional checks. In the last 6 years the only checks I've received were first paychecks at a new job (before direct deposit was set up) and my covid stimulus checks.
I'm in Europe where the situation is different: checks haven't been used in appreciable numbers for 30 years or so. It's all online or paper transfer orders. If you get a pre-filled paper transfer order, you can type (or scan and OCR I suppose) the same data into the online form.
Europe is a big place, but my understanding is that the US is the outlier here and Europe is relatively similar in this regard.
The only time I really saw checks used was when I was a child ~30-35 years ago and my parents used them. I did once cash a check from an elderly relative, but that was very unusual and only happened once. I didn't even know it was still possible to do that, my reaction was more like if someone had handed me a stack of punch cards to run on my computer.
There hasn't been anything an average person used checks for in the last decades in Germany. Except a few elderly people, nobody uses checks and there are no rebates via checks at all.
Cash is still fairly common, and manufacturer rebates are basically not a thing. If they were, you'd send them an account number (IBAN = bank ID + account number at bank) to transfer the money to.
In fairness, manufacturer rebates have pretty much (mercifully) disappeared in the US as well as they were basically a scheme to mentally make you account for a lower price you wouldn't end up being rebated for various reasons.
I am in the UK and I have received two cheques in the last year, both for small amounts.
As it turned out, my bank rejected both because they were made out to [middle name] [surname] rather than [firstname] [surname]. Ironically the former is unique (probably) whereas they had another customer with the latter.
What's a check? As the saying goes, 'I'm too European for this'.
On a more serious note, the last time I saw a cheque in the UK was my grandfather balancing his cheque book in the mid 80s. It really has been that long since they were in general use in the UK, at least.
Just like with the prevalance of Apple/iPhones, the US banking system is global outlier.
Things you can't do with my banking app you can do with the web site:
- Extract your transactions to excel/csv
- Use OpenBanking
- See all my accounts on screen at once
- Sharedealing
- International transfers
But people are right, banks trust the mobile app more, and realy on it as an MFA device, so even if you use the website you still need the app.
