CISA Certified Information Systems Auditor – Question0915

In which of the following payment mode, an issuer attempts to emulate physical cash by creating digital certificates, which are purchased by users who redeem them with the issuer at a later date?

A.
Electronic Money Model
B. Electronics Checks model
C. Electronic transfer model
D. Electronic withdraw model

Correct Answer: A

Explanation:

Explanation:
In an electronic money model issuer attempts to do this by creating digital certificates, which are then purchased by users who redeem them with the issuer at a later date. In the interim, certificates can be transferred among users to trade for goods or services.
For the certificate to take on some of the attributes of physical cash, certain techniques are used so that when a certificate is deposited, the issuer can not determine the original withdrawer of the certificate. This provides an electronic certificate with unconditional uncertainty.
For CISA exam you should know below information about payment systems
There are two types of parties involved in all payment systems – the issuer and the user. An issuer is an entity that operates the payment service. An issuer holds the items that the payment represents. The user of the payment service performs two main functions- making payments and receiving payments – and therefore can be described as a payer or payee receptively.
Electronic Money Model – The objective of electronic money systems is emulating physical cash. An issuer attempts to do this by creating digital certificates, which are then purchased by users who redeem them with the issuer at a later date. In the interim, certificates can be transferred among users to trade for goods or services. For the certificate to take on some of the attributes of physical cash, certain techniques are used so that when a certificate is deposited, the issuer can not determine the original withdrawer of the certificate. This provides an electronic certificate with unconditional uncertainty.
Electronic Check Model – Electronic check system model real-world checks quite well and thus relatively simple to understand and implement. A users write an electronic check, which is digitally signed instruction to pay. This is transferred to another user, who then deposits the electronic check with the issuer. The issuer will verify payer’s signature on the payment and transfer the fund from the payer’s account to the payee’s account.
Electronic Transfer Model – Electronic systems are simplest of three payment models. The payer simply creates a payment transfer instructions, sign it digitally and send it to issuer. The issuer then verifies the signature on the request and performs the transfer.
This type of systems requires payer to be on-line and not payee.
