Can one IC card be used for multiple people?

One IC Card, Multiple People? A Clear No.

The convenience of IC cards (Identification Cards) is undeniable, streamlining access to various services and simplifying identification. However, a common question arises: can one IC card be used for multiple people? The short answer is a resounding no. This is not simply a matter of convenience; it’s a crucial aspect of security, accountability, and maintaining the integrity of the services offered.

Many systems that utilize IC cards for access, booking, or registration enforce a strict one-person-per-card policy. This is because each card is registered to a specific individual, creating a direct link between the user and their activity. Sharing a single card undermines this fundamental principle and introduces several significant problems:

• Security Risks: Sharing an IC card compromises security. If the card is lost or stolen, multiple individuals are vulnerable. Furthermore, it becomes impossible to track who is responsible for specific actions performed using the card. This can have serious implications for accountability in cases of misuse or fraudulent activity.

• Data Integrity: Accurate record-keeping is essential for many services. Using a single card for multiple people corrupts data associated with each individual, making it difficult or impossible to analyze usage patterns, track attendance, or effectively manage resources.

• Violation of Terms of Service: Nearly all services that require IC card registration explicitly state that each individual must possess their own registered card. Sharing a card constitutes a direct violation of the terms of service, potentially leading to penalties or suspension of access.

• Difficulty in Contact Tracing and Emergency Response: In situations requiring contact tracing (such as during a public health crisis) or emergency response, using a single card for multiple people significantly hinders the ability to effectively identify and reach individuals who may be affected.

In short, while sharing an IC card might seem like a simple solution, it carries significant risks and violates the fundamental principles underpinning its usage. Always ensure that each person has their own registered IC card to avoid complications, maintain security, and comply with the terms of service. Remember, the process of registering individual cards is designed to protect both you and the integrity of the services you access.
