In such a wiFi operating scene as apartment, downtown village, campus, users pay for their own micromails, but there's always some.Fillcard: The owner sends a card for cash, the school starts with a full-size campus network charging card, a weak net or an unstuffed user can buy a card to open it. The card is a plastic card with a card code, but it really runs off, and the three things that are not handled well, namely, security, surrogate, reconciliation, and a leaky bag of money.
First, the need for a full-value card. V7 Authentication & Billing supports micro-mails, payment treasures, minor programs, foreign trio payments, and also supports payment of a full-value card."There's a phone, there's a bank card."The user; the full-value card addresses other categories of people: parents don't pay on line, the landlord collects cash to a user with a voucher or the operator wants to do a distribution.——You sell the cards to agents, and the agents sell them to end users. This is a business model, not a technology-friendly problem.
The first risk to the full-value card is a card's overflow and password leak.A card has scratched the coating, with a number and password on it. If the passphrase is watched, photographed, and copied from the print, transport, sales chain, it has been stolen before the user has reached it. The defense line on the side of the system is that each card has a code which is not specified in the database and which is owned by Hash; that Carmi is one-off, and this card immediately after the scratching value does not expire for a second time; and that the system locks into successive errors of the same card number to prevent violent tests. This mechanism is the basis for the payment of the full-value card, which is available in V7 products but which are specific to the operational parameters of card printing, password length, validity date, and which must be matched by its own.
The second risk is...Card and card section management. Each batch of cards must have a separate section. For example, 00001 to 005,000 is for Agent A and 00501 to 01000 is for Agent B. This segment is not just for good looks but for reconciliation.——This card is sold out. Who should the money be? If all cards are mixed in a pool, and the account is not split by one agent at the end of the month. V7 supports the broker's independent interface and independent privileges, and the agents see their own section of the card, and they don't see each other's users or running water, which is the basis for multi-agent mode.
The surrogate is a very realistic layer of apartment scenes.Many of the condos are for the manager: the chief takes a pre-charge from the operator, the tenant gives cash to the owner, and the head of the building collects the account number from his agent's back office. In this mode, the chief is both a biller and a small conduit, and he has a manageable balance pool.——The operator first gave the manager a $10,000 proxy account, and each resident had 50 per person he had, his own balance being reduced by 50, and at the end of the month he had as much in his hand, sold as he could see in the system. V7 supports this agent independent WEB port and access segregation, and the owner can only enter into it to see his user and his own balance and not to see data on other buildings.
The most easy dispute to create is the substrate:The chief said he was full, the system didn't come. The guests said he didn't get it.The root of this triangular dispute is that there's no credible flow. The correct answer is: no matter how the building owner replaces it, three records are left in the system.——The manager's proxy account is attached to the home phone, and a call for the client's account is issued. The bill was discussed earlier, and it is used here: the replacement is not intended for the owner, but for the tenant; the check must be sent to the guest's cell phone, so that the tripartite reconciliation is justified. If there is nothing on the back of the building, there is no information on the guest's phone, and then it is scratched every month.
The full-value card has another real problem:Card validity and carry-over of balances. A card is printed out and cannot be valid forever. The normal puncture card has a validity period, which can no longer be used. But the user has scratched it and has filled the balance in the account number and cannot be scraped after the card expires.——The two concepts are separated. The card itself is valid and the balance in the account number follows the account number strategy."Duration of the card"and"Duration of account balances"And when you tie it together, the user feels trapped: I'm loaded with money. What makes you think that you have to go out of time? As Kari said, the refunds and balances must be written in advance, and the full-value card is valid for this category as well.
On the reconciliation, the charge card stream and the wires pay for the current.Separate the accounts.The amount of the micro-mail treasure is directly paid, and a third party payment platform returns can be reconciled; the charge card is first withheld from the agent balance, which is also an advance from the operator. The two links are different: payments on line are user-specific.→Payment platform→operator accounts; billing is a proxy advance→Operator ' s advance pool→User accounts. At the end of the month, reconciliations are checked separately: right to online entry and system charge records, right to agent advance pool balances and card sales in agent hands, not in a table.
This is a power boundary:The full-value card is a tool for operations, not a forgery-proof technology product.V7 can be a Carmihashi, one-time use, block management, proxy decentralization, streaming, but the card itself is a physical security component (radium, watermarks, security codes) that does not fit into the system. The risk of counterfeiting a card under the line is handled by printing channels and physical protection."The system can prevent fake cards."。
Finally, a business detail: the full amount is printed without the first coming up. A small batch of test numbers is printed and two weeks run from printing, transportation, proxy sales, user-to-account charging, month-end reconciliations are missing, and a lot of operators put in large quantities. Many start with the first load card, and a few thousand copies are printed up one time, finding that code rules are wrong, the proxy section is not broken, the reconciliation is not reconciled, tens of thousands of cards are simply destroyed. One such puddle would suffice.
The card looks like a plastic card, which is a system of security against forgery, numbering, proxy power-sharing, surcharges, and split-account reconciliation. Cartwright uses one-time, block-by-section, to the account sender himself, to separate streaming on line, and to zoom in on small batches, either of which is not done, may turn into leaky money bags.
