Encypted Scratch Card Serial Number Pairs

This feature allows Agents to create cash collection transactions using a serial number (the visible number on a scratch-card). The Pay-out Agent/Bank can then pay-out the transaction to the beneficiary when the beneficiary supplies a PIN (hidden number on the scratch card) which is linked to the serial number in the back-end. Note that the creation and printing of scratch cards must be handled by a third party.
