For u to withdraw money at atm... Good for overseas usage but not in local...
If the card is not linked to any current/savings account, I do not think it is a good idea to have cash advance.
OK, on a broader scale, you need to distinguish between following:
- Card issuing bank
- The account the card is linked to
- The network the card uses for cash withdrawal
Turn over your card and look at the logo. If you see Plus logo with Visa cards or Cirrus for MC that it means that the card can be used at any ATM which is connected to the respective network.
Now, if the credit card in addition to the credit line is linked other current/savings account at the issuing bank, one can withdraw money at ATMs form those accounts. But should be careful because some ATMs won't distinguish (or not able to) between those account types and cash withdrawal might post directly as cash advance. Good luck fighting with the issuing bank claiming that you did not do cash advance.
If the credit card is not linked to current/savings account but comes with PIN, using this card at ATMs will always result cash withdrawal posted as cash advance. Using PIN at non-ATMs, but with automated machines (like ticket selling machines) - well, your luck will vary. It might go as a credit card transaction or might as cash advance, depends on a machine's setup.
In short - unless your credit card is Chip and PIN card, you should not need to use (or better - should not use) PIN anywhere.
