Are RFID Tags Safe? Currently, RFID technology is widely applied across various fields, including warehouse management, goods and asset tracking, access control, etc. RFID cards are also used in time attendance cards, library cards, vehicle cards, and more. However, alongside the benefits RFID brings, many people are still concerned about the safety and security of RFID cards. Could personal information be easily stolen? The following article will help readers find the most accurate answers. Stay tuned!
Answer: Are RFID Tags Safe?
RFID technology allows users to identify objects through a radio wave transmission and reception system, supporting fast, efficient, and accurate management. An RFID system typically includes: RFID cards, RFID readers, antennas, and system software. RFID technology is highly regarded for its safety and high level of data security, providing absolute satisfaction to users.
Are Rfid Tags Safe
In fact, RFID cards CANNOT be stolen, especially in high-security systems where each card has a chip tied to a unique number. Therefore, it can be said that RFID CARDS ARE VERY SAFE.
RFID cards store a large amount of data with over 2000 kb of memory, including identification and serial numbers. Currently, there are various types of RFID cards, either read-only or writeable, allowing users to add or delete any data. You can find more details about RFID card types in this article: “Common Types of RFID Cards and Their Applications“
RFID cards come with different identifier codes that can reach up to 32 bits, equivalent to 4 billion unique codes. Therefore, duplicating or mistakenly identifying a card is highly unlikely. As of now, RFID card security is the best, and no other card type can compare with RFID cards.
RFID Tags are very safe, but nothing is absolute, and the security of RFID tags is no exception. RFID cards may be at risk of having their information read illegally using specialized RFID readers. This is possible because RFID cards can be read from a distance. Additionally, RFID cards can be counterfeited. Moreover, RFID cards can be exploited to track users’ location and behavior, raising concerns about the personal privacy of RFID cardholders.
Is Rfid Absolutely Safe
In fact, many customers’ RFID cards have had their data stolen using specialized cloning devices. In our previous article, we discussed how to copy RFID cards as well as ways to prevent RFID card cloning. You can refer to it here: “Simple And Easy Way To Copy An RFID Tag”
6 Suggested Solutions to Enhance RFID Tag Security
In light of the risks of RFID card data theft, we have compiled some suggestions to improve security and ensure RFID card safety as follows:
Use Activation Switches
These are buttons that can be pressed or toggled to activate the RFID card. Implementing an activation switch in RFID cards ensures that the information on the card is only read with the cardholder’s permission. Of course, this also means that unauthorized individuals CANNOT clone or access the card’s data without permission.
Use RFID Tags with Protective Shields
RFID cards with protective shields typically have an insulating layer that can be removed, but only with the cardholder’s consent. This solution is highly recommended for personal RFID cards and asset management. However, for large-scale warehouse management, this solution is not recommended.

Mutual Authentication
With the mutual authentication solution between the RFID reader and the RFID card, the card decodes the signal using a special key (which both parties are aware of). If the decryption fails, the card will send the information back to the reader for re-decryption. This method only allows data transmission when both the reader and the card are verified as genuine devices. This solution effectively prevents unauthorized access by third parties.
Password Lock
This security enhancement solution for RFID cards uses a 32-bit password lock, equivalent to 4 billion different codes, which is sent before the RFID card allows data transmission. Password locks are commonly used to protect passive UHF systems with limited computing capabilities.
Cover Coding
In some cases, the signal from the RFID reader can be stronger than the signal from the RFID card, allowing unauthorized individuals to collect data easily. In such instances, cover coding can be applied, where the reader requests the card to provide a random number, and the card sends this number to the reader. The subsequent data transmission uses this random number, making it difficult for a third party to hack the RFID card and decode the information.
One-Way Encryption Solution
This is an effective method to prevent eavesdropping or unauthorized reading. By applying one-way encryption, all data sent to the card is encrypted, and the data transmitted from the card to the reader is decrypted.
