Kisha,
1098-T is for tuition and fees payments. Being cash gift card, there would not be a way for a student to use that to pay their tuition balance. In my mind, this would NOT be something reportable on 1098-T. May want to confirm with institution legal group. Now, could this be income to the student and reportable on 1099? There is a $600 reporting threshhold for filing 1099 form for miscellaneous income, so if below that, would not have to do 1099 forms. Again discussion with institution legal group may be helpful. Most of us here are not tax experts.
