• IVR (Interactive Voice Responding): for payments carried out through automatic responders used as an alternative to Internet portals
• Contact Center: conceived for call center telephone operators who may use it separately or   integrate it with their own Customer Relationship Management systems 
• Digital terrestrial: the solution for payments carried out via an interactive decoder.

The result of a ten years' work in the innovative payment systems sector, @POS was designed to offer different multi-channel payment solutions capable of satisfying all the requirements of companies and of their end-users. Thanks to the @POS_payRID component, it allows management of payments by debiting the purchaser's current account.

The service can accept the following payments:

• MO/TO (Mail Order/Telephone Order), through API XML and server to server connection 
• in redirect mode, using the SSL standard
• in redirect mode, according to the Verified by Visa and MasterCard SecureCode protocols
• in server to server mode according to the Verified by Visa and SecureCode protocols
• with manual entry by the merchant directly from the @POS (MO/TO) back-office

In the case of MO/TO transactions, merchants must integrate in their systems the collection of data relating to the credit cards, which are then forwarded to the @POS service to obtain authorization.

Alternatively, the service can accept redirect payments by redirecting the purchaser to @POS. In this case, the data relating to the payment instrument do not go through the merchant's portal but are entered directly in SIA's secure server.

The merchants having a prior mail order system (for example Call Center), to obtain the complete order and the payment details, may use the back-office graphic interface directly to forward the payment request and obtain authorization.
