We've had one request - I too couldn't find any information on them except that the way it works is the company sends a debit through a wire instead of a credit to your customer. The request we had for this was from a business customer and they were looking at a new payroll service who wanted to use the "reverse wire" to debit the business. Reading through the contract we were very uncomfortable with it because it seemed that if they send the debit through the wire transfer system, there was no way to return it if the customer didn't have any funds. Second, how were we going to know the dollar amount was correct each time, what if they sent the wrong amount. Talking with the company that wanted our customer to do this they made a big deal about why we wouldn't do it and kept trying to say other banks do it all the time. We weren't going to budge, we said do it ACH or we're not doing it at all. If anyone has any experience with these, I'd love to hear about it as well.
