Tri-Rail Easy Card Question

Hi, all, I'm a bit of a transit nerd who collects transit cards, and we're going to be flying into FLL at the end of the week, and planning on taking the Tri-Rail and Miami Metrorail to get around. I noticed on the Tri-Rail website that the Easy card picture listed, shows a SFRTA Tri-Rail Easy Card, and on the MDT website it shows a miami-dade easy card, with a green backdrop and a palm tree. Are these the same card, or should I buy one or the other. Thanks.
