Press the "Add value" and follow the instructions. You can pay by cash (notes or coins) by inserting it in the slot, located at the upper right corner, or the NETS, at the upper left corner.
If your EZ-link card is inside your wallet. You don't need to remove it, just place your wallet on top of the slot "Please place here". It will automatically read your EZ-link card.
