In order to implement tokenization for secure, online payment processing, you will need to use Authorize.net as your Gateway. Use this link, https://account.authorize.net/ui/themes/anet/oauth/PricingPage.aspx?resellerId=11442, to sign up for your account.
If you already have a merchant account, you can proceed with utilizing Authorize.net for the gateway only. Once your Authorize account is set up, you will need to login and enter in your Merchant ID (MID) and Terminal ID (ID) for your existing merchant account. That is what allows the funds to be deposited into your existing bank account.
If you need a merchant account, you can use one of your choice. If you don't have a preference, we recommend Atlantic Merchant Services, atlanticmerchant.com. Our contact there is Scott Chappell, (919) 851-9799. Be sure to mention Clarity Connect as they then look at your account in the context of all of the Clarity customers who use their services. This tends to get our customers better rates than they would otherwise.
Even if you have an existing processor, you might want to have Scott give you a quote to see if he can save you some money.
