The daily limit is based on the purchase limit policies in place with the bank for your bank account. Where the transit authority is processing variable fare payments (e.g. fare by distance or time), they may only process a single payment through to the bank for a trip, or even for a day where a daily cap on fares is in place, regardless of whether or not you tap your card many times to make transfers. In that case, they use the additional taps to record where you travelled, so that they can calculate the net fare owing at the end of the trip or day. Please check with the transit authority to understand how many transactions may be processed against your bank account for a day's travel, so that you can compare that against any transaction count limits that may apply to your bank account. Please refer to the bank if you are unsure about transaction count limits or related charges for your bank account.
