"At our school, we use barcodes in the cafeteria. This year the codes were printed on flimsy paper and laminated. The scanner was not able to read them consistently and many simply got lost. So students then had to manually enter a student ID number. Memorizing a 7 or 8 digit number was difficult for most students and they always needed assistance from me."
