If the remaining IC card balance such as PASMO is less than 220 yen, how do I use a municipal bus?

There are the following two types.
①How to pay after charging on the spot
Please ask the crew to charge the car.
※In the car, you can charge 1,000 yen bills, 2,000 yen bills, 5,000 yen bills, and 10,000 yen bills.
There's no change.
※Please cooperate with the charge before boarding as much as possible for smooth operation.
Charges can also be made at stations, convenience stores, and supermarkets.
②Method of paying the shortfall in cash or by another IC card
After deducting the balance in 10 yen units, you will need to pay the shortfall again.
