There is no limits for Contactless payments on my credit cards. I did have to sign for a $100 purchase and a few merchants make you sign no matter what the price. What Credit Cards are you referring to or are you talking Debit Cards.

At Whole Foods I didn't have to sign until I had over a $100 purchase and at Macy's I signed for a +$100 purchase.
