With Zaldo you can check the balance of your bip! card in real time using the NFC reader on your smartphone. In addition to the balance, you can obtain the following data directly from your transport card: • Last 3 trips made, bus or subway. • Last 3 balance top-up. • The current Metro fare. • The number of rides available based on your balance. Zaldo is compatible with bip and TNE public transport cards issued in Chile. Zaldo does not record any personal data. The card reading is done locally on your device.
