On the back of cards:
"Not valid without authorized signature" on AA Platinum and Chase cards.
"Not valid unless signed" on Brooks Brothers.
Other cards just say "Authorized signature" or "Cardmember signature".
I agree it doesn't do much, but it's definitely something CC companies nominally require.
Very useful: SchwabPlat, CSP, IHG, Costco (was AA Plat), Freedom, SPG
Somewhat useful: Discover, ED (was EDP), BCE, Hyatt
Plan to PC: Prestige to DC
SD with activity alerts, might close: Arrival and Brooks Bros
Might add: Proper business card, CSR, Ritz, Delta Gold, First Tech, BofA Travel PH
