A high tech lunch

I like the quality of the lunch we can get at the canteen.

But what was even more surprising for me when first came here was the high tech payment system here.

All you do this touch the bottom of the screen with the pink tray with the empty plates.
Than it automatically calculates the price and calories. Also provides the breakdown.

How do you pay for it?
Just place a card like can oyster card used in the tubes in London.
No cash accepted.
Don't have enough charged? There's a charge machine right next this payment machine for those people.

All done. No cashiers needed here. Nice and easy.
