I am a B24-eps programmer and I have experience about the following projects: Project: B24 Classic to B24-eps Migration Project Description: The components and processes considered on this project are: - Acquirers and Authorizers by working on ISO-87 messages for credit and debit cards. - Information synchronize process from CAF table to CARD data source and from USOS table to LIMIT data source. - Prevalidations such as CVV, PIN, ARQC, Status of Card, Expiration Date of Card, and Limits. - CSM tables implement a lot of business rules and define the behaviour of the transactions. - Device Handler for NCR and Diebold. Project: IVA Digital Services Project on B24-eps Description: The IVASD CSM component compares a part of the content of field 43 from ISO-87 messages to the records from a CSM data source, so it evaluates which of the nine tax rules given by SRI of Ecuador are matched to charge taxes or no. Then these taxes are put into a CSM token and are sent to the authorizer. The idea is only to charge taxes to international transactions that have matched some of these nine rules. Project: EMV Field 55 Project on B24-eps Description: The HISOE CSM component can receive and send EMV information in field 55 of ISO-87 messages through interfaces on B24-eps. Project: UPF Standin Project on B24-eps Description: The transactions are acquired from UPF and through BSI communications sent to B24-eps where is connected the authorizer, but when it is not available then the transactions are authorized by the standin process on B24-eps. The defined business rules depend on the commerce that sent the transaction from UPF. The limits defined for each commerce are different. It is necessary that the standin process can identify who is the commerce to apply the limit corresponding. Project: Online Limits Project on B24-eps Description: The LMTB24, SEQB24, and TRXB24 CSM components save the LIMIT records on three CSM data sources that are sent from a CARD HOLDER system through ISO-87 messages with a CSM token. Then online transactions read these data sources to get LIMIT that has to check them. This solution was necessary because our customer - BR Bank - asks their customers which are the LIMITS that they want for their debit card. Project: ISO87 to FILE UPDATE Converter on B24-eps Description: The HISOS CSM component becomes an ISO87 message into FILE UPDATE message. Then the FILE UPDATE message is processed on B24-eps by saving a record in the CARD file on B24-eps.
