quick questions. maybank ezypay is available on all maybank cc right? or islamic cc dun have?

im undecided between two maybank cards now

these two,

PETRONAS Maybankard Visa and Maybank Islamic Ikhwan American Express Gold Card-i

i just received my maybank cc. anyway for new applicant there is one slip that u need to sign and return to the bank. but i don't receive any return envelope together with the package

so my questions is do i've to post it? or return it to the branch that i applied?

oh is it? i thought we can use the card straight away after activation thru mb2u

imo this slip is just for verification purpose that the card is received in the right hand..they just want to verify the signature with the form that we filled in..

from my understanding, correct me if im wrong, this promo is also valid for shop who didn't provide the ezypay plan? that means we can buy from any shop and call the bank to convert it?
