D4 is now gainfully employed. After more than a year of extensive training, numerous tests both oral and written, she is now an officer in the one of the major banks here in Manila. She now acts like a crazy person sourcing for legitimate receipts for her tax deductions. She has so many perks too and one of them is a premium health plan for her and hubby and I. She gave me the health card and the other day and as I read the benefits and coverage it seemed similar to the Blue Cross Blue Shield NC health card. D4, hubby and I now have two health cards each. My question is can we use them simultaneously?
