Your My SNCB account - My eWallet
The eWallet is personal and is linked to on or more season tickets on your MoBIB card.
Via your My SNCB account, you can use the balance available in your eWallet to renew the season ticket linked to your MoBIB card.
To pay with your eWallet at the ticket counter, let the advisor know in advance and show them your MoBIB Card.
