Serious NETS CashCard

I have this NETS CashCard but I no longer need it for carparks and ERP.

I still have some credits and was wondering what I can do with it? Heard that I can make purchases at selected retailers.

If yes, do I need a pin for the cash card?

You can transfer the money remaining in your cash card into your bank account. I did that for an expired cashcard about 2-3 years back and transferred the balance money inside the expired cashcard into my bank account.

You can easily effect the transfer at a ATM and just follow the options on the screen along the way.
