Everything below is taken directly from their site:
instaCASH EFT Preference
An instaCASH deposit is an instant EFT. Like a regular EFT, an instaCASH deposit withdraws money from your bank account to fund your NETELLER account. However, with instaCASH, the deposit amount becomes available to you instantly, whereas regular EFTs take 4-5 business days to clear. It can take up to 4 business days for the funds to leave your bank account with an instaCASH deposit, but NETELLER makes the funds available for you to transfer immediately.
Electronic Funds Transfer Preference
Using EFT, you can transfer funds directly from your bank account to your NETELLER account. These transactions are free, but require at least 4-5 business days to clear. To use EFT, simply register your bank account with NETELLER. Available to US and Canadian members only
Credit Card Preference
Major credit cards accepted. Please note many North American banks decline credit card transactions for certain classes of merchants. This determination is made by the banks and not NETELLER or the credit card companies. If you encounter a problem using your credit card, we suggest that you try one of our EFT bank deposit options, which are quickly becoming the most popular and secure way to transfer money online.
Bank Wire Preference
Bank wire deposits can be initiated from any bank worldwide. Please note that bank wires are different from EFTs (Electronic Fund Transfers). For bank wires you must physically go into your local bank, with the appropriate NETELLER Bank Wire information, to initiate a bank wire deposit to your NETELLER account.
NETELLER Card Preference
When you sign up for the NETELLER Card you will be able to transfer funds from your card back to your NETELLER account. NETELLER Card deposits are instant.
