MedBank have recently introduced a new Credit Card platform Cred+. There is a requirement to migrate
account and card details from the existing banking platform PCBS on to Cred+.
Account IDs of the cases requiring data transfer will be held on a SQL database. The requirement is that,
for each account ID specified on the SQL database, the following data must be read from the PCBS
application and input into the Cred+ application:
Account ID

Product Type

Name

Address

Date of Birth

Card PAN (Primary Account Number or credit card number)

Card Issue Date

Card Expiry Date

Once the data has been successfully input into Cred+ the correct record on the SQL database will be
updated to indicate data transfer is complete. All work queues will be encrypted, however due to the
sensitivity of the data, MedBank insist that a single robot account does not have access to both PCBS and
CRED+ systems.
The following high level design has been proposed:
