I'm in Australia. All the major and I'm pretty sure all or almost all of the minor banks and bank-like businesses (Building Societies and Credit Unions here) use a thing called PayID. I can send almost everybody I know money just by using their mobile phone number or email address, and the transfer happens from my account to theirs literally in seconds. I can also send money to anybody's BSB/Account Number, and that happens pretty much overnight. Writing a check feels like an archaic thing my parents used to do, like dialling a rotary telephone or sending a fax. I'm pretty sure if someone offered me payment by check, I'd turn it down assuming it's a scam. (I'm 56, for comparison)

BSB and account transfers are also largely instant. New and large transfers may take overnight.

Also, you missed an important part: zero fees.

It’s amazing how different the customs can be.

I’ve only received a check once in my life, in 2004 from a US company. I could not cash it with my regular (online) bank in Poland. I had to open a foreign currency account with the national bank, just for this check, and go to their special customer service department in person, at their HQ. It was like bringing them an alien artifact.

Hah. Once I had to get a wire transfer from a foreign company for some consulting work. I had to open up a new bank account just for that. It's like a mirror image.

use Arbonum, it does not take any hidden commissions, but immediately shows how much the commission will be. Usually from 3%.

It's also fast, easy to understand and the technical support works 24/7
