I've wondered this too. I got a letter from my bank saying they were converting their debt cards from Visa to MC. Hum, I pulled out my wallet and checked, I already had a MC debt card. A few days later my new and still MC debt card arrived. I figured no problem, I'll get around to activating it one day. Then within a day or two the bank started sending me emails reminding me to activate the new card? Weird.
