Not sure if this was discussed previously, but I was at the Amsterdam airport buying a train ticket and the card kept getting rejected from the ticket machine, despite having setup a travel notification.

After calling up Chase and speaking with an airport employee, I found out it was rejected because the card doesn't have a pin, like all European chip cards. I was in Europe for two weeks and this was my only encounter of this happening. I wanted to share so hopefully no one else has to deal with those frustrating 20 minutes of confusion.
