The second sounds OK, but only if the chosen field is truly a candidate key.
"Customer" does not sound like one - suppose you have two 'John Smith's?
This is why most real-world applications use unique numbers or codes.
Of course you could (probably) differentiate the 'John Smith's by address,
but then the address has to be typed in as well as the name. A code is
much easier.

It all depends on the nature of the data.
