Using NFC tags and smartphones to design a reliable mechanism to pick a child up from school

When school is over, parents picking up their child can be disoriented. This design provides a convenient mechanism to identify either the parents or any authorized person who can pick up their child. This design also uses the smartphone NFC function and NFC tags to identify the authorized individual. This design provides a simple user interface to manage the school class table of children who are to be picked up. For a class of students, this design uses a NFC tag ID to construct this table which is prestored in the teacher's smartphone. When either the parents or the authorized persons want to pick up their child, the teacher's smartphone scans the parents' or authorized individual's NFC tag and verifies the NFC tag with this table of children who are to be picked up within a short time. This confirmation procedure for the NFC tag ID provides a reliable mechanism to use when picking up children from school.
