    • Disputes related to the public transit services that were provided or not provided in connection with the tap and/or about the price of these services must be conducted between the TA and the Rider.
  2. Transit fares purchased by lost or stolen card is the Rider’s responsibility. UniTiAg may offer means of mitigation such risks. The means may include:
    • Alerts via SMS, emails, or Apps upon reaching certain cumulative fare amount threshold within certain periods of time.
    • Blocking OTRBs permanently or for a period of time.
  3. If an OTRB overdraft occurs, it is the Rider’s responsibility to pay it as soon as possible.
    • UniTiAg may use automatic OTRB replenishment for this purpose.
    • UniTiAg may establish a grace period for the overdraft repayment.
    • Rider may limit their overdraft liability.
  4. If the Rider blocks or cancels the Card account with the card issuing financial institution, it is the Rider’s responsibility to stop or block the related OTRB with UniTiAg.
