They also use card skimming devices to "clone" your card and use pin hole cameras to capture your pin while you are typing it. They can even bump into you with a device that will initiate a small purchase from your card that can "tap" 
In addition to its features, I believe that banks have also enhanced security measures. To combat criminal activities such as skimming, banks have taken the proactive step of embedding chips in cards to safeguard against card cloning. The introduction of contactless features, in my opinion, is a notable advantage of these small chips present in every card. Consequently, fraudsters would need to gain physical possession of the card if they intend to misuse someone else's card for multiple tap transactions.Other forms of fraud may only become apparent in 2 or 3 years when the bank's security systems have been compromised, causing harm to several individuals and subsequently coming to the attention of law enforcement.
