摘要

A vending machine incorporates a reader that reads an identification (ID) card, and a verification unit to determine the authenticity of the ID card. A control circuit utilizes software to calculate the age of the owner of the ID card, and enables a principal circuit to dispense tobacco if the calculated age is equal to or beyond a predetermined age. The transaction is disqualified and the ID card is discharged if the age is less than the predetermined age.
