I use the "Paywave" on my Visa card quite a bit but have not yet been able to use the contactless payment (RFID) feature on my Canadian Amex Plat card. One of the reasons i got to thinking about this was that i had a real catch-22 experience the other day at London Drugs; i was just buying a small item, ideal for this quick payment. so i went to the self serve cashier, scanned, clicked pay, and put my amex up to the reader. the display read something along the line that it couldn't accept this method and to please insert my card. so i inserted my card and the machine then told me to swipe. so the ridiculous part was that when i placed my card at the top end of the slot, the RFID reader read the chip and beeped telling me to insert the card. i couldn't get the card past the swipe mechanism because the RFID chip would get read. finally i just used my visa which seems to be the solution to trying to pay with amex.

I haven't been able to use this feature with my amex anywhere. are you having success with your amex card and contactless payment?
