ID Tags: The Hidden Risk of Scanning Identification Tags

Be Aware of the Privacy Risks of ID Tags: Scambusters #1246

We see luggage tags at airports, wristbands in hospitals, identification bands at events, and tickets at bus stations. These small tags help with identification and tracking, but they can also reveal personal information. Depending on the tag type, a simple barcode, QR code, or RFID chip can share details you may not want public.

Not every tag is a security risk, but it’s important to understand what information is stored, who can access it, and how it could be misused. Before you attach a tag or let someone scan it, know what information you might be disclosing.

Let’s get started…

ID Tags: The Hidden Risk of Scanning Identification Tags

A scannable ID tag is a badge with a barcode or QR code that contains personal information. These tags are common in schools, hospitals, transportation services, and offices. They make access and record-keeping easier, but if the data is not well protected, it can expose names, photos, and sensitive information. Understanding what your ID tag holds and how to keep it safe can help prevent identity theft.

You see badges with barcodes everywhere. People scan them to enter offices, check in at schools, or pick up medication at pharmacies. While these tags speed up daily tasks, many don’t think about what data is on them or who can read it.

These tags connect a unique code to a central system. The tag itself may show only limited information but scanning it can reveal a larger profile stored elsewhere.

What Other Names Are Given to This Type of ID?

Scannable ID tags have different names based on the industry and the technology used.

• Barcode ID badges – The most common term refers to tags that use traditional barcode technology.
• QR code ID tags – Badges use Quick Response (QR) codes. These codes can store more information than regular barcodes.
• Proximity cards – ID tags that use RFID, or radio-frequency identification, work without needing to scan them visually.
• Smart ID cards – A general term for ID tags that have chips or codes inside them, which connect to digital systems.
• Access badges – Often used in workplace security settings.

No matter the name, the main purpose is the same: connecting a physical card to a digital identity record.

What Kind of Facilities Use These ID Tags?

Scannable ID tags are used in many industries, including:

• Schools and universities – for student identification, library access, and campus security.
• Hospitals and healthcare facilities – for identifying patients, allowing staff access, and tracking medications.
• Corporate offices – for managing employee access and tracking attendance.
• Government buildings – for managing visitors and granting security access.
• Airports and transit hubs – for employee IDs and, in some cases, traveler IDs.
• Retail and warehouse facilities – for tracking inventory and managing employee shifts.

Different organizations keep various types of data on their ID tags, based on what they need to track.

What Type of Personal Information Appears on the ID Tags?

The type and amount of personal information on a scannable ID tag can differ by facility. Common details often include:

• Full name
• Photo
• Date of birth
• Employee or student ID number
• Department or role
• Access permissions (which areas the badge can unlock)
• In healthcare settings: patient ID numbers, insurance information, or medical record numbers

Some organizations display only a reference number on the visible barcode. They keep sensitive information securely stored in a backend database. Other organizations include more details in the barcode itself, which increases the risk if the card is lost, stolen, or scanned by an unauthorized device.

Is There a Risk of Identity Theft With These ID Tags?

Scannable ID tags can increase the risk of identity theft, especially when:

• The barcode or QR code contains unencrypted personal data (such as a Social Security number or full birth date).
• The ID tag is lost or stolen and can be scanned by anyone with the right equipment.
• A facility’s backend database linked to the ID tag has been hacked. This breach has exposed personal information stored in the database.
• Scammers use portable barcode scanners or smartphone apps to read badge information without the owner’s knowledge.

The risk level is closely tied to how well an organization protects its data. For example, a hospital ID badge linked to medical records is much more sensitive than a simple office access card that has no personal information.

What Concerns Have Come From ID Tags?

Researchers focused on security and privacy advocates have expressed concerns about scannable ID tags over the years:

• Skimming – Unauthorized scanners can read RFID or barcode data from a distance without needing to touch the card.
• Data breaches – Centralized databases connected to ID tags are appealing targets for hackers. If they breach one system, they can access the information of thousands of people at once.
• Lack of encryption – Older ID systems sometimes keep data in plain text on the barcode. This makes it easy to read with basic scanners.
• Tailgating and impersonation – Lost or cloned badges can let unauthorized people into secure areas.

Many organizations are upgrading to encrypted smart cards or multi-factor authentication systems. These systems do not depend only on a scannable tag. This change addresses concerns about security.

How Would I Know if My ID Was Taken Fraudulently from an ID Tag?

Warning signs that your identity might be at risk due to a scannable ID tag include:

• Unfamiliar accounts or credit checks showing up on your credit report.
• Bills or statements for services you never used.
• Notifications from your employer, school, or healthcare provider about a data breach involving ID or badge systems.
• Unexpected access logs showing your badge was used at times or locations you didn’t visit.
• If you receive mail or emails about accounts or applications that you did not start, be cautious.

If you see any of these signs, act fast. The longer you ignore fraudulent activity, the harder it will be to fix the problem.

How Can I Protect Myself?

Here are practical steps to reduce your risk:

• Ask your organization how it stores data.  Find out if your ID tag uses encryption and what information is included in the code.
• Use an RFID-blocking sleeve. These affordable sleeves stop unauthorized scanning of proximity cards when you are not using them.
• Report lost or stolen badges immediately. Prompt reporting lets IT or security teams turn off a badge before someone can misuse it.
• Monitor your credit report regularly. Free annual credit reports and credit monitoring services can help you spot suspicious activity early.
• Avoid sharing your badge or ID number unnecessarily. Treat your ID tag like sensitive personal information. It is not just a convenient item.
• Ask about data breach notification policies. Find out how your school, employer, or healthcare provider will notify you if there is a breach.

The Bottom Line

Scannable ID tags, like barcode badges, QR code IDs, and proximity cards, are common in schools, hospitals, offices, and other places. They help manage access and track personal data. However, these tags can increase the risk of identity theft if they hold unprotected personal information or if the database storing this information is hacked.

Be aware of signs like unfamiliar accounts or unusual badge activity. To protect yourself, ask whether your personal information is encrypted, use RFID-blocking sleeves, and check your credit regularly.
