Super Schlüsseljojo. Our daughter used this order at the food counter their school canteen trigger with a chip their food. So the chip is not lost - but it must not he ever ranhängen somewhere off or. He is firmly attached to the belt loop of trousers or skirt and consumption for the time being not to be removed again. So they can go completely relaxed to chip over the reader and after the meal, despite chip, go play on the playground. The tape is long enough and everything seems very stable. The whole thing is very light and small. Very easy operation. Our Daughter is sooo excited! Highly recommended!
