RFID, Tyvek, and Other Identification Methods


Whether you’re running an apartment complex, a business, or just a one-day event, you need to make sure that only authorised people can get in. You need to ensure that those who have been selected for entry for whatever reason are allowed to get in while those who are not cannot gain access. Controlling access can be done through electronic or technological means. It can also be done using human resources. The decision is one based on your needs as well as your budget.


Radio frequency identification is a fairly simple process. There is an RFID chip and an RFID reader. In a passive chip system, the reader will send out an electromagnetic signal. That signal will then be responded to by the RFID chip. The system is called passive since the chip uses the energy of the radio waves to power it and send out the corresponding signal. Every reader is equipped to read a few radio frequencies, and the chips are equipped to respond with a specific frequency. This is how many items in stores are tagged.

In a retail or library setting, an expected radio frequency sets off an alarm indicating that someone is shoplifting. In the entry control setting, the radio frequency reader will give the right person access. That can means lifting a gate, unlocking a door, or whatever is necessary. The benefits of an RFID system are that you don’t need anyone to man the entry; the automated system can handle it. Also, you can rapidly change which radio frequencies are accepted. For example, if you have RFID entry to your business, you can reprogram the chips and readers to a new frequency if a disgruntled employee has to be terminated. You can quickly change who is allowed access.

If you need a simpler or a one-time use system, simple tyvek wristbands will suffice.


Tyvek is a polymer material you have probably seen used for the siding on houses. It is a durable, flexible, and waterproof material. It’s strong enough to be used as protection for homes, and will work great for wristbands. The tyvek bands will be long-lasting and durable. They can be used for one-time usage as well. For example, if you are hosting a concert and want to allow only paying customers in, you can give wristbands to those paying customers. A security guard or a bouncer at the door can then control who gets in based on the wristbands.

They’re also great for venues that sell alcohol, but allow underaged people into the venue. Instead of slowing down the bar service by checking identification at the bar, you can check identification at the door and then wristband those who are allowed to drink. Tyvek is a perfect material for this since it is not easy to remove it and give it to someone else. It will not degrade like a paper wristband if it gets wet.

If you’re looking to restrict access to an area, there are many different options you can choose from.
