OK, but aren't those just as readily reversible as checks? I've read that banks readily reverse even cashier's checks. Which was the basis of a common Craigslist scam. Maybe it's just the Zelle doesn't care to be bothered.
Every transaction you make with a credit card is an ACH payment behind the scenes, so yes they are readily reversible. The banks are hands off with Zelle though, any payment is like giving call, they have no duty to reverse funds over disputes between you and receiver unlike PayPal type services. You have to trust who you are giving money to.
Zelle is for PERSONAL payments only. It's for sending money to friends and family and people you trust and know. It's free for both the sender and receiver BUT you won't get any protection. Once it's sent, it's sent.
Don't people read? It's on Zelle's website "send money in minutes to your friends and family". I also asked my bank about that and got told there's no protection unless somebody hacked into your account. Yet, if you sent the money, it's your responsibility.
BTW: PayPal really sucks if you receive a lot of personal payments. I got my account frozen because PayPal got nosy and wanted to know more about 15 transactions. It took me a while to get my account unlimited. So, that's why I use Zelle for personal payments and use PayPal only for purchases. I would ditch PayPal but I don't have any option for now.
