In the banking world EFT is considered an "umbrella" term under which all the following would fall:

Types of Electronic Funds Transfers (EFTs):
1. ACH (Automated Clearing House)
2. Fedwire (aka: Wire Transfer)
3. CHIPS (Clearing House Interbank Payments System)
4. SWIFT (Society for Worldwide Interbank Financial Telecommunications
When customers send ACH files to the "originating bank", the bank will typically require the file to be forrmatted according to NACHA (National Automated Clearing House Association) guidelines. ACH items fall into two main categories (1) consumer (example: direct deposit of payroll) and (2) corporate (example: vendor payments). ACH files include a field called "Standard Entry Class". These are the Standard Entry Classes for NACHA formatted ACH files:

- PPD (Personal Payment or Deposit) These can be either credits (like payroll) or debits (like mortage payments)
- CCD (Corporate Concentration or Disbursement) These can be either credits or debits
- CCD+ (Corporate Concenration or Disbursement Plus Addedum) This is exactly like a CCD item, but with an 80 char addenda strip.
- CTX (Corporate Trade Exchange) This is like CCD but with up to 9,999 addenda strips of 80 char.
