Q: What is an ACH transfer? 
A: Automated Clearing House (ACH) is a network that electronically processes transactions for WSFS and other banks.  These transfers typically take a few business days to process and for the money to be available in the receiving account.  When you transfer funds from an account at one bank to at another bank over the internet or when you pay a bill online you are likely completing an ACH transfer.  An ACH transfer is the most common form of electronic money movement.
