Subject: strategic information system

cases: Scan it app

potential problem:

• Multi-variety errors

This occurs where a user has selected a product which is available in a number of varieties or flavours, such as a tins of cat food chicken, beef, fish etc. The consumer simply scans the same variety several times to speed up the process and then places all the items in the bagging area. While there is generally no immediate financial loss for the retailer, the inventory system will now incorrectly assume it has sold more/less of any given Stock Keeping Unit.

• Double Scanning

This occurs when a consumer accidentally scans and then subsequently pays for the same item more than once. This can lead to overpayment by the consumer and the corruption of store inventory records.

• Barcodes have less security than RFID (Radio-frequency identification)

Barcodes are easily counterfeited, and the data itself is always readable. Data is not secure as the information did not has the ability to encrypt.

Not all the barcodes are genuine. There can be malicious barcodes set up by cybercriminals. If a user happens to scan a malicious barcode, the system could potentially be taken over by the hacker. Since the USB which connects the scanner and the computer acts as a secondary keyboard, the hackers could easily gain access to the operating system

What is the solution for this potential problem? Explain!
