Why do the banks give out these useless EFTPOS cards that you can't use online?

Question

They have a 16 digit Mastercard number (starts with a 5) but they don't function as such and have no cvv2 number

Answer 1

Why don't you ask your bank their reasoning, and see if you can get a better card?

Answer 2

have you looked at the back of the card (near the signture line?)

do you see some 3 digts *thats tat CV2 number)
