RFID vs Personal Identification Number for Access Control

July 25, 2021

Are you tired of misplacing your access card, forgetting your PIN number, or constantly having to type it in? Well, the technology world has brought us new methods of access control. In this blog post, we will go through the pros and cons of RFID technology and Personal Identification Numbers (PINs) to help you choose the best option for your business.

RFID Technology

RFID, short for Radio Frequency Identification, uses radio waves to wirelessly transfer data between a tag and a reader. RFID tags contain an antenna and a microchip that allows them to transmit data to the receiver.

Pros

  1. Easy and Fast: Accessing a secured area is as simple as waving an RFID card or key fob at the reader. No need to type or swipe anything; it's effortless and quick.

  2. Secure: RFID cards and key fobs are challenging to duplicate or forge. Additionally, some RFID tags come with encryption technology that adds an extra layer of security.

  3. No Contact Required: With the ongoing pandemic, minimizing contact is crucial. RFID technology allows you to grant access to an area without having to touch a surface, thus minimizing the spread of germs.

Cons

  1. Costs: RFID technology is usually more expensive than traditional access control systems, and it requires an initial investment in readers, tags, and software. However, the cost can be offset by the time and cost saved from reissuing lost or stolen access cards.

  2. Power Outages: If your access control system relies on electricity, a power outage could render the RFID readers inoperable.

Personal Identification Number (PIN)

When a person needs to access a secured area, they enter a PIN number into a keypad. If the PIN is correct, the door or gate to the area unlocks.

Pros

  1. Inexpensive: PIN-based access control systems are relatively cheap and require no hardware to be imported, unlike RFID systems.

  2. Easy to Change: If someone loses or forgets their PIN, it's easy to reset it or issue a new one.

  3. Multiple Users: PIN access systems can handle multiple users without requiring additional hardware beyond the keypad.

Cons

  1. Lack of Security: PINS themselves can be easily shared or guessed, making them less secure than RFID systems, especially if the access control system doesn't include additional security features.

  2. Slow: Entering a PIN into a keypad takes longer than waving an RFID card or key fob at a reader, which can create bottlenecks in high traffic areas.

Conclusion

In the end, the choice between RFID and PIN-based access control systems depends on your organization's specific needs. RFID is more secure, faster, and requires no contact, but at a higher initial cost. PIN-based systems are inexpensive and easy to set up, but less secure and slower.

While RFID has an initial higher cost, it may be the better long-term investment because of its quicker and easier usage. On the other hand, if security is not one of the primary concerns, PINs are an inexpensive and practical alternative.

So the question is, "RFID or PIN?" well, only you can truly answer that, but we hope this blog post provides you with the right tools to make an informed decision.
