Just go to your card details where you have to enter your pin. When it shows up, you click on the details button next to your card. Afterwards, you will get a pop-up that looks like the following image:

The access token will then be shown to the right. I have cropped it out of this screenshot for obvious reasons.
thanks for your help. but that button isnt available in my login, maybe its because i m using a virtual card?
