This is not an actual charge, but an authorization that Linden Lab requests from your credit card company.  This is a standard way for businesses to verify a payment method when you establish an account.

Once the authorization is received, which confirms the account is valid, they then rescind the authorization.

At no time is the US$1.00 actually charged, though the authorization may appear on a credit card statement as such. The amount may show as "pending" or "authorized" for a few days, but then will drop off the account entirely.
