<prompt> Human: As you can see its a subdomain of chase.com and I found it in the Samsung pay app as a promotion, so Im 90 sure its legit but also 90 paranoid so Im kind of afraid to enter the information its asking for.It wants the card holders last name last 4 of the card and the zip code. Previous Chase promotions through Samsung pay have been much easier to enter. Literally all you had to do was link your Chase credit card to your Samsung pay account and then purchased five things. 5 cash back is pretty awesome. I pretty much exclusively use my credit card for things. Even when Im being responsible. So Id benefit a lot from this.  <response>: Perhaps that link shows something different to you? I just see Chases standard cashback offer for the quarter. Nothing fishy here; this is how the card works.
