A biometric machine can prove when you arrived. It cannot prove that the rules arrived with it.
Every university that installs a biometric attendance system makes the same announcement: accountability has arrived. Before applauding, ask the one question the announcement never answers. Whom has the machine caught, and whom has it never so much as inconvenienced?
That question is the whole argument. A control that catches only the least powerful people in the building is not a control. It is a sorting device, and what it sorts is not the diligent from the idle but the exposed from the protected.
The machine itself is innocent; it holds no views about anyone. What matters is the policy wrapped around it, and the people who operate it. Any attendance system can be put through four tests.
First, does it bind the people who run it? A rule that exempts its own enforcers fails at once. Consider an institution where annual honoraria, and the allowances paid after each semester of an evening programme, are drawn by people whose attendance is never examined, and who check their own records and write their own reports. The same scanner, in the same building, is then policing the junior lecturer while taking the senior’s word. Courts have a name for this. In Yick Wo v. Hopkins, in 1886, the United States Supreme Court struck down a licensing rule that looked neutral on paper but was refused to some two hundred Chinese laundry owners and granted to almost every other applicant. The law was fair on its face, the justices said, but administered “with an evil eye and an unequal hand”. A rule is judged by whom it is actually used against.
Second, who keeps the keys? A biometric server is only as honest as whoever administers it, and an administrator can export, edit, backdate and quietly lose records. Now consider an institution where the IT directorate is run by a junior employee holding an additional charge, that familiar bureaucratic device by which a subordinate is made to act in a senior’s place. The charge is granted by the administration, renewed by the administration and withdrawn by the administration. With it come the allowance, the title and proximity to power. Nobody needs to issue instructions. Dependence does the drafting. When the person who audits the powerful owes the post to the powerful, the audit becomes a courtesy: reports appear when wanted and fail to appear when not, and a glitch in one week is forgiven while a glitch in another becomes a charge. No bribe is required. A favour that can be withdrawn is a leash, and both ends know who is holding it. I describe a structure, not a person. But structures reliably produce the behaviour they reward.
Third, can the watched see what is recorded? Attendance data in the sole custody of one side is not a record. It is a reserve. Late minutes are not billed when they are incurred; they are banked. Months pass in silence. Then someone votes the wrong way in a committee, queries an appointment, or asks how a purchase was approved, and the account is presented in full. Twenty years of blameless service becomes a dossier of four-minute sins, while a loyal colleague finds the same mornings quietly marked as work done elsewhere. That is how a timestamp becomes retaliation. Where data can be read, edited and withheld by one side alone, nobody can tell a lapse from a lever.
Fourth, can the accused be heard before the record becomes a sentence? Machines err. Devices go down, enrolments lapse, fingertips worn by chalk and marker ink refuse to register. A fair system puts a hearing between the log and the penalty. An unfair one skips straight to the notice.
Pass all four tests and the machine is an instrument of discipline. Fail any one and it is discretion with a circuit board. Fail the second and the third together, and it is something worse: a private tribunal with a public mandate.
The danger, then, is not that the scanner will punish everyone. It is that it makes everyone technically guilty and leaves the choice of whom to charge with whoever holds the file. That is how a campus can be governed without a single order being given, and how injustice acquires a procedure.
Even a fair machine would measure the wrong thing. The scanner certifies that a thumb arrived; whether a lecture did is another matter. Once a measure becomes a target, economists remind us, it stops being a good measure. The teacher who is punctual and reads from old notes satisfies the system. The one who arrives ten minutes late and holds a seminar students are still quoting a decade later does not. An institution that cannot tell them apart has not gained accountability. It has lost its judgement and bought a gadget to hide the loss.
Students watch all of this without a word being said. No young person needs to be taught about hypocrisy; it can be read off the notice board. They see who is chased, who is excused, and which rules grow soft at a certain height in the building, and they conclude that rules are for those who cannot afford to ignore them.
The remedy is neither exotic nor expensive. Publish the rules once, in writing, and apply them from the top downwards. Put the system under an independent custodian rather than a dependent one: no additional charge, no favours to renew, and an audit by someone outside the chain of command. Give every employee a view of their own record, and keep a log of every edit, outage and access. Pay honoraria and allowances only against attendance verified by an independent office; nobody should certify their own presence. And let teaching be judged by teaching: classes held, students heard, theses supervised, work published.
A scanner can settle when someone arrived. It cannot settle who has the right to ask. Until the machine is pointed, with equal candour, at the people who bought it, and kept by someone who owes them no favour, it is not an attendance system. It is a pecking order with a power cable.
