RFID Locks Help Secure Homes

It all started with RFID-based locks for cars in the 1980s. Now, most new vehicles come with keyless entry systems that allow drivers to zap their automobiles open instead of fumble with keys. Some cars can even be driven without a key, as long as the driver’s RFID-based key fob is close by.

For decades, RFID locks have improved security and eased access to buildings. Most people who work in modern office buildings open doors with cards rather than keys, and many of these systems rely on RFID. Hotels have typically used card entry systems based on magnetic strips. However, many hotels and resorts are currently upgrading these to RFID-based wristband entry systems that can also be used for cash-free buying on site.

New and creative uses

As the use of RFID spreads, technology vendors are coming up with new and creative applications for RFID-based locks that will make products more secure and protect individuals.

For instance, some companies have developed locks for overseas shipping crates that work together with sensors to alert authorities about possible tampering. Others have developed digital door locks for homes that can be used alone or with optional PIN numbers.

Home improvement

As a homeowner, if you install RFID locks on your doors, you will never be able to lock yourself out again. You will never have to call a locksmith, and you will never have to replace expensive keys that were stolen or lost.

Users simply approach the lock with their RFID-enabled cards or fobs. The interrogator in the lock recognizes the unique ID on your card, and in you go. Locks are pickproof since they have no keyholes, and some even offer built-in alarms to deter thieves.
