I use the TSD EFS card regularly, but it does still require an account with cash available. We have a bank account we’ve had forever but never use as a checking account. We keep a few hundred in it when traveling. I’m thinking about the FMCA card only to add stations in areas where the EFS card doesn’t have any. Hoping there are new stations available. I have a 36 gallon tank so stopping more often. Some day I’ll upgrade to a 56 gal tank, but that’s a different discussion.
