RFID vs Magnetic Stripe Cards for Access Control
Looking to secure your property or keep track of employee attendance? Two popular technologies for access control are RFID (Radio Frequency Identification) and magnetic stripe cards. While both of these technologies have their pros and cons, which one is the best fit for your specific needs? Let's find out.
RFID Technology
RFID technology uses radio waves to communicate data between a reader and a tag. The tag, which is usually an adhesive sticker, contains a microprocessor and a small antenna. When the tag comes into range of the reader, it automatically sends out its data.
RFID tags can be active or passive. Active tags have their own power source, so they can be read from a greater distance than passive tags. Passive tags, on the other hand, do not have their own power source and must be read from much closer range.
Pros
- RFID tags can be read from a greater distance than magnetic stripe cards.
- RFID is more secure than magnetic stripes because it is difficult to clone RFID tags.
Cons
- RFID technology can be more expensive than magnetic stripe technology.
- RFID has limited read range for passive tags.
Magnetic Stripe Cards
Magnetic stripe cards are a popular option for access control because they are inexpensive and easy to use. These cards contain a magnetic stripe on the back, which is read by a swipe card reader. When the stripe passes over the reader, the data on the stripe is transferred to the reader.
Pros
- Magnetic stripe cards are inexpensive and widely available.
- They are easy to use and do not require any special training.
Cons
- Magnetic stripe cards can be easily copied or cloned.
- The magnetic stripe can be damaged by exposure to magnets or other sources of interference.
RFID vs Magnetic Stripe Cards: Which one to choose?
When it comes to access control, choosing between RFID and magnetic stripe cards depends on your specific needs. If you need a more secure option and are willing to pay a little more, RFID is the way to go. If cost is a major factor and you don't need a high level of security, magnetic stripe cards may be the better choice.
