The charging standards for Xi'an bus cards and bus codes are the same, and they are all charged according to the unified bus fare.

When taking a bus with a bus IC card, passengers enjoy a fare discount of 0.91% off for one swipe of the card, and 40% off for multiple swipes of the card (i.e. 0.4 yuan). When all IC card fares in the carriage are insufficient to cover the current fare, passengers must pay the actual fare.

Users who use Alipay bus codes (Xi'an subway and bus) can receive additional Sesame Credit points on the basis of enjoying the same discount.

Therefore, whether you use Xi'an bus card or bus code, the charging standards are determined based on the actual fare. The specific discounts and supplementary fees depend on the user's payment method and fare.
