Why palm vein, optional on every gate
A card tells you what was handed in. Never who handed it.
Lanyards snap. Cards drop in car parks, stay in yesterday's jacket, and get lent "just for today". Published workplace surveys keep finding the same thing: about one in three badge holders admits to lending their card, and four in ten have lost one. A school gate at 7:50 in the morning is exactly where a borrowed card works best.
We watched real gates before we built for them, and our own field research is blunt: most guards check the colour of the lanyard, and never the card hanging from it. That is not laziness; it is what any human does at hour four of a shift. It means the card system is not being defeated by forgers. It is being waved through by design.
Better than facial recognition, on purpose
Palm vein is voluntary: identification happens only when a hand is deliberately laid on the reader. Facial recognition reads you whether you agreed or not, and a face carries gender, ethnicity and religious dress, and, now that faces authorise payments, a key to your financial life. A vein pattern lives beneath the skin and carries none of that. It answers exactly one question, whether this is the registered person, and nothing else.
Trusted where money moves
In January 2026 the UAE Central Bank unveiled payment by palm, the region's first biometric payments solution (The National, 28 January 2026). When the country's own banks trust a palm to move money, a school can trust it to release a child. The readers are an optional add-on on both terminals; the Emirates ID chip remains the foundation.
Identification should always work, not be bypassed when so desired. A lanyard can be glanced past. A hand offered to the reader, in one second, cannot.
