GestPay puts to the first place the safety in the management of the transactions, tranquilizing the purchasers on the treatment of the data on Internet and the shopkeepers relatively to the possibility of swindles.

The New Standards of Safety

• Protocol ssl3 to 128 bit: the communication between browser and the serveur of the bank is currently guaranteed by a transport in code SSL3 to 128 bit (the highest standard of safety with the certification serveur side). In this way, the parameters are transmitted through the browser of the customer, they are in code and so, the consumer won’t be able to interfere anyway in the talk between merchant and the bank.

• IP addresses: to increase the safety, the merchant will have to indicate one or more IP addresses of the serveur that will communicate with the serveur Banca Sella: it will verify, to every call, an intercrossed control on the passed IP merchant and the calling IP address. The merchant will have to modify its pages of answer on the basis of the result of the transaction (URL OK and KO) so, they will decrypt the answer of the bank.

• Reiteration of the communication: in case of impossibility of connection to the serveur of the merchant, the sure serveur Banca Sella will visualize to the customer a "virtual receipt" that reassumes the data of the transaction and it will carry out a predefined number of attempts to establish the communication. Exausted these last ones, the customer will visualize one page containing the information on the payment predisposed by Banca Sella in substitution of the page of the shopkeeper. An other series of ulterior attempts will carry out from serveur to serveur, at regular intervals, until the guarantee of happened communication. If, within 24 hours, the communication has not been established, the help desk will contact directly the shopkeeper.

• Java Class: the merchant that convenziona with GestPay, he will be able to download from the website Sellanet a multiplatform Java class, adaptable to whichever system. Its function will be to encrypt, throught an algorithm of symmetrical key with one new key, generated daily directly from the systems Banca Sella, the data that will be subsequently pass to the serveur Banca Sella. On thewebsite Sellanet various examples “Copy and stick” will always be available in the most diffuse program languages.

• Dependability about the communication server/server: thanks to the direct communication server/server, the merchant is sure to receive an answer of the bank about the transaction, also when the shopkeeper closes the browser before obtaining the answer.

• Page No Display: the Page No Display offers the possibility to the shopkeeper to acquire on his own website, all the informations necessary to carry out a payment. For being able to acquire directly shopkeeper data, it is important to have a sure server (a website protected by a digital certificate).
