WiFi network billing system if you want to make up-front payment mode——Users fill first and then use——The most common thing in schools is to pay for the payment of micromails and money, some of which are linked to the campus card system. The docking appears to be a connection with the payment interface, but there are a lot of practical details that can be made without making it possible to pay. Users who have no pay-back, refunds or reconciliations are not matched. Each one is an operational accident.
Reciprocal mode and security requirements for payment interfaces
WiFi network billing systems pay third parties, usually in two ways: API straight-line and page jump. API straight-links are user inputting payment information on the charge system ' s full-value pages, payment platform API is used backstage to complete deductions and users experience good but high security requirements. The page jump is when a user clicks on a charged value to a paid platform to complete payment, and then pays for a checkback system that is safe but has a break point. The interface is preceded by a test environment for payment platforms to run through the process and move on to the production environment.
Delays and anomalies in charging to accounts
The WiFi network billing system receives feedback notifications from the pay-for-the-money platform and updates user balances. Normally, this process is a scyg-to-check, but it happens in an anomaly. There are several common anomalies: payment of platform deductions has been successful but callback notices have failed (network problems), billing systems have received returns but balance updates have failed (database issues), users have paid but closing browsers has led to the non-excontinuation of the jump-back charge system."The money's been withheld, but the balance hasn't changed.". WiFi network billing system requires a charge-back mechanism——Check regularly whether payment platforms have unrecognised payment orders, or, if so, file a voluntary supplement.
Design and approval mechanism for the refund process
The WiFi network fee system has several types of refunds: user-filled demand for refunds, change in the set price, dropout balances, mispayment. The approval process varies from one category to another. Users have offered to limit frequency and amount and prevent misuse. The package changes are calculated automatically. The withdrawal balance is checked out with the SAS. The refund process will leave a full log including the applicant, the approving officer, the amount of the refund, the channel for refund, and confirmation of receipt.
Reconciliation mechanisms are the bottom line against fund risk
The financial reconciliation between WiFi's network billing system and the third-party payment platform is a bottom line against risk to money. The reconciliation is simple.——Match the billings recorded in the billing system with those provided by the payment platform, which are regular and not consistent. Reconciliation frequency is recommended to be done once a day, T+1 reconciliations being today for all yesterday's charges. Reconciliation anomalies need to be graded: small differences (within $1) may be fees or errors of input, only if manually confirmed after recording; large discrepancies must be immediately checked, possibly through the bug or malpractice of the system. The reconciliation reports should be filed regularly as a basis for financial auditing. Without the WiFi network accounting system for the accounting mechanism, there is no open exposure of funds risk, often long before problems arise.
Speciality of the campus card interface
If WiFi network billing systems are to interface with the campus card system, and the micromail payment treasures, they differ. The campus card system interface standards are not uniform across schools, some WebService, others HTTP API, or a database link.——The balance of WiFi must be paid immediately and without delay when students use the school card charge. The campus card system usually has a limited flow, peaks may be slow to respond, and WiFi network billing systems need to be retested and timed out.
Security management of payment vouchers
WiFi web-based billing system matching platform requires various vouchers——API keys, business certificates, and callback keys. If the documents are leaked, the assailant can fake payment notices to fill any user. Security management of the documents has several points: they cannot be written in a configuration file or code, but they must be stored encrypted; different environments (testing, production) have different forms; documents rotate regularly (at least half-yearly); access documents have minimal authorization, not all operators see them.——The WiFi network billing system is a financial security gap in schools.
