I am aware that Sakae Sushi is quite efficient in a sense they have
a hot water tap on each table and a computerised system to take
your orders. But I never knew they had radio frequency
identification (RFID) magnetic tags below each tag to keep track of
freshness of the food. So apparently, there is a centralised system
and smart robotic arm that would remove expired plates. Wah, so
high tech sia.
This method is good for keeping manpower efficient and
productive...
What do you think?
P.s. I saw it here.
