advantage of EFT?

The immediate problem: I have 1 more personal check left and 2 imminent bills this short month.  

Do I order more checks, do electronic checks, EFT, or what??I know our society hates paper in all its forms.  Paper is electricity, internet, and cybervirus-free however, so black-out friendly).  Plus, I do not want a computer / net controlling my financial life.   EFT debits can bounce like checks can, right?  So why are EFTs do desireable for business?  And if they do bounce, I will still get charged, like with checks, right?  

Checks have check #s so that on a register you can tell what went through and what did not, and what I may have forgotten to record.  I would like something equivalent so I can be alerted about what I didn't write down.  

Anyway, what is the advantage of EFT over paper checks? why do so many stop accepting checks?

You don't waste $.55 mailing it or spending time dropping it off.

All the transactions that go through your bank account will have transaction numbers so that you can enter in your check register or however you keep track of your payments.
