回复：POD vs ITF

They are very similar. It depends on bank and state law: 

POD - The cash in Bank account becomes "paybale on death" to designated beneficiaries when account holder dies .

TOD - The ownership of securities in brokerage account must be "transferred on death" to the beneficiary then account holder dies.

ITF - It's also called "Totten Trust"; the asset is paid/transferred to designated beneficiaries when account holder dies. It's not required but it applies to account holders who has trust. 

These days most of bank using POD.

QQH me if you need any help when doing estate plannig.
