The American President is more often called as POTUS as POTUS is an abbreviation of the President Of The United States of America. The reason for POTUS is because America loves 1-2 syllable catchy titles. So are words like FLOTUS, SCOTUS, VPOTUS, etc. I don't see it widely used except media.
Introducing the mihealth card. The mihealth (my health) card is a permanent plastic health ID card that's issued to Michigan Medicaid, Emergency Medicaid, Children's Special Health Care Services (CSHCS) and Adult Benefits Waiver (ABW) beneficiaries. The mihealth card replaced the monthly Medicaid blue paper card.
EMV card. An EMV card, also called a chip-and-PIN card or smart card, contains a special computer chip to store card account data. Unlike magnetic-stripe cards, every time an EMV card is used for payment, the chip creates a unique transaction code that cannot be reused, thus stymying counterfeit card fraud.
