The card says SIGNATURE in small print below the Visa logo and has a different number for customer service than my Platinum did. I called the number and the voice said "Visa Signature" but otherwise sounded the same, giving the same type of card info and options. Concierge was not an option and their phone number is not on the back of the card, so I'll have to add it.
I like the way Chase does their Visa Signatures: the white border on the Visa flag is removed and the Visa logo itself is metallic. The BofA Visa Signature (and other banks) leave the Visa logo as is with the Signature below it. I miss the "Signature Band" that they used to have. It looked classier.
Congrats on your upgrade!
