Which of the following is NOT an example of an ACH payment?

A wire transfer is not an example of an ACH (Automated Clearing House) payment because wire transfers are a different type of electronic payment system that operates independently of the ACH network. Wire transfers facilitate the direct transfer of funds between banks and typically involve real-time processing, offering immediate availability of funds.

In contrast, ACH payments are known for batch processing, where transactions are grouped together and settled at designated times, which can result in a delay in fund availability. Other examples such as personal loan payments, supplier payments, and salary payments can all be processed through ACH as they are commonly recurring or bulk payments made electronically.
