Fare Deduction Function of Card-Connected Card Readers

The fare deduction function of card-connected card readers is mainly achieved through the following steps:

1. Read Card Information

• When swiping the card, the reader reads the information on the transit card or payment card, such as the card number and balance.
  

2. Verify Card Validity

• The system verifies whether the card is valid, including whether the balance is sufficient and whether it is within the validity period.

3. Calculate Fare

• Distance-based fare: Calculates the travel distance based on boarding and alighting records and deducts the corresponding fare.

• Sectional fare: Deducts the fare based on the number of sections traveled.

• Flat fare: Directly deducts a fixed fare.

4. Execute Deduction

Cardlan system deducts the corresponding fare from the card balance and updates the balance.

5. Record Transaction Information

• Transaction information (such as time, location, amount, etc.) is recorded in the system or on the card for future queries or reconciliation.

6. Feedback Result

• The card reader displays the deduction result (e.g., success, insufficient balance, etc.) and emits a prompt sound.

7. Process Discount Policies

• If there are discount policies (e.g., student cards, senior cards, or transfer discounts), the system automatically calculates and deducts the fare after applying the discount.

8. Data Synchronization

• Transaction data is synchronized with the backend system for data analysis, report generation, etc.

Notes

• Maintain sufficient balance: Avoid inconvenience due to insufficient balance.

• Check transaction records promptly: Ensure accurate deductions and address any issues in a timely manner.
  

The fare deduction function of card-connected card readers relies on the integration of hardware and software to ensure accurate deductions and secure transactions.
