Visa and Mastercard both have their advantages at online casinos, but Poli is better in almost every way except availability. Visa and Mastercard may carry transaction fees, and withdrawals can take from 1 to three days. If you use Visa and Mastercard, you will need to share the card details with the casino. Although it is safe to do so at reputable, licensed casinos, many players are not comfortable to share their card details. Poli provides an alternative. You can log in to your own internet banking account through the Poli servers, which means that you have a buffer between your casino account and bank account, and the casino cannot access your banking information. However, one drawback to Poli is that it is only available in Australia and New Zealand, so it is not as widely available at online casinos as the Visa and Mastercard options.
