Top up your mKaart anytime
If you are using public transport you can top up your mKaart without going to a sales point or to a vending machine, provided you have an Internet connexion and a user account on the www.mshop.lu website.
Once you have linked your mKaart to your user account, you can choose from the whole product list available online.
Once you’ve bought a product, you have to wait until 4 am the next day before taking your mKaart to a "Pick Up" validating machine at any railway station in the Grand Duchy of Luxembourg.
A "Pick Up" station is a validating and information station that allows you to automatically load products you have already bought on the www.mshop.lu website.
