Question

which of the following ways of tracking inventory is the most secure and expensive? (select the best answer.)
○ physically counting the items
○ barcodes
○ rfid tags

Explanation:

To determine the most secure and expensive inventory - tracking method:

• Physically counting items is time - consuming and error - prone, not the most secure or expensive.
• Barcodes are relatively inexpensive and less secure compared to RFID in terms of data security and tracking capabilities.
• RFID (Radio - Frequency Identification) tags use radio waves to identify and track items. They offer high - level security as they can store more data, have a longer read range, and are harder to tamper with. Also, the technology and infrastructure for RFID are more costly to implement compared to barcodes and physical counting.

Answer:

C. RFID tags
