Frankly speaking, I'm not quite sure how NexG actually works. Assuming it's same to PB VE, when I want to verify my Paypal account, Paypal will charge my card for USD1.95 and the amount will be deducted directly from my card. Public bank sent me a Card Usage Notice everytime I make purchase online. In that notice, they will state the time/date of transaction and the transaction description.

For Paypal, verification purpose, you'll see something like 1234PAYPAL--*EXPUSE on the notice. Notice that the first 4 numbers are your verification ID that you need to enter in the paypal page to verify and remove limitation of your account.

I'm not sure NexG does the same. If they don't, you might probably want to check your card account online. Usually there's a transaction details where you can also find that code.

I think if you plan to buy something from ebay for USD100, I would suggest you to have at least RM400 in the account. Just in case cos for PB VE case, RM25 in the account is considered as a deposit and can't be used. Which mean I will only have RM375 in the account. You might want to have extra $$ in the account if the item price excludes shipping =)
