The Emera Bank feature was implemented on 21/September/2014. Using the Emera Bank, you are able to track all of your money transactions (PokéDollar & Nuggets) in the last few days.
You are able to see what time the transaction was made and also who it was made out to (if gifted). Received pokedollars are in green, deductions from your account are in red.
The Emera Bank page can be accessed by clicking your Pokedollars or Nuggets on your userbar.
