As to your questions, this is what it says.
How do I activate my account?
Simply transfer a minimum deposit of $500.00 via PayNow to Singapura Finance UEN 196900340N by indicating your account number under the Reference field to activate your account.
I have activated my Vivid Savings Account but I did not receive my Vivid Card.
Your Vivid Card will be mailed to your registered address or mailing address within 7-14 business days after the creation of your Vivid e-Wallet on your mobile device and the successful activation of your account. Watch for our SMS and email notification.
Also, this is something extra to take note..
I deposited $500.00 via PayNow to my Vivid Savings Account at 10 a.m. this morning. However, I still cannot see the new balance in my account now at 2 p.m. Why is this so?
As deposit made through PayNow does not have a fixed format reference field, we need to verify each payment via PayNow before crediting the money to the Vivid Savings Account. As such, the crediting will not be immediate. As a general rule, deposit received before 4 p.m. on a working day will be credited to the account on same day. Payment received after 4 p.m. on a working day or on a weekend/public holiday will be credited on the next working day.
