Zelle, while supported by most banks, seems to be the payment of choice by scammers. Zelle apparently has a 'we believe the buyer despite your evidence to the contrary as a seller' policy. As for payments at a swap meet... I used a Square app (remember them?) and sold a LOT more stuff simply because many chose to use a card over cash.
Good info and feedback.
I had heard there was no way to refute a transaction with Zelle..
The square app uses a credit card. Could someone go back and say the item was not what they believed, broken, never received ??
