I have a Chase credit card that is linked to S-Pay. There was an unauthorized online charge yesterday. The Chase android app is installed on my phone and is set to issue notifications of every charge so I was able to catch it immediately. After talking to customer service and then transferred to Chase security team, my card was canceled and a new one issued. The newly issued card won't arrive for a few days. However, shortly after my phone call the Samsung Pay app had a notification regarding the card; the new number was already pushed! I was able to use S-Pay today at the grocery store as if nothing happened. I thought this was quite awesome and wanted to share.
