Is RFID technology safe?

With the development and popularization of RFID technology, this technology is being used in many security identification scenarios and gradually comes into people's vision. Faced with this new thing, many people are worried that the content in RFID electronic tags is easily stolen, so they cannot As an effective method with security or Access Control. Today I will take you to learn about RFID technology and see if this technology can be applied in the field of security identification?

There is no doubt that those RFID electronic tag IDs used for access management can be copied and used to hack access control systems. If you try hard enough, you can probably hack every technology ever invented, including biometrics. Since there are people working on the dark side of power, there are also good people. They are constantly coming up with safer solutions. Thanks to the continuous efforts of RFID technology practitioners, the security of RFID technology is now constantly improving.

RFID access control management

How does RFID technology achieve a high level of security?

“Smart Mode” is a perfect example of this fundamental rule of RFID technology, which is to always be one step ahead of your competitors, in this case competitors who are the experts and who can break your RFID technology based access control system,” Smart Mode" will cause their attempts to fail. "Smart Mode" is included with the RFID UHF reader Master01. It is the parent mode of the reader and can be started in every working mode: polling, autorun, autorun+ or autonomous run. RFID Readers with "smart mode" can identify such tags independently of the EPC or TID number. This is the main function of "Smart Mode". Assuming a hacker just cloned an unprotected EPC number, they could do the same thing with a TID number, but it would certainly be more difficult. But an RFID reader equipped with smart mode can easily and immediately identify that the tag has been illegally modified. No matter the cloned number is EPC or TID. When using smart mode, copying the EPC or even the TID on another tag will not authorize that tag (e.g. someone will not be able to gain access).

This is because Smart Mode enables the reader to identify its own tags regardless of their EPC or TID. Such a process runs in the underlying reader. The result is that no database needs to be created logically, the tag's EPC or TID can have any value and the tag can be identified.

And, in any case, the EPC number in the tag will be reprogrammed, not rendering the tag unrecognizable. Such tags will still be recognized as correctly assigned tags to the system. So even if someone tries to change the content of a tag (take away someone's access rights), no harm is done to the tag owner because the tag will still work fine.

The new generation of RFID devices will be replaced by Gen 2.0, and almost all readers produced by large companies can work according to the latest standards. Gen 2.0 offers even greater security, combined with "Smart Mode" which gives users almost 100% certainty that no tags will be illegally copied.

In conclusion, it is necessary to say that RFID is actually more secure than most technologies nowadays. User security is protected not only by ever-improving devices (readers and tags), but also by the technology itself.
