HOW RFID WORKS FOR ACCESS CONTROL
Most access control systems now use a technology called Radio Frequency Identification or RFID. RFID technology is combined into contactless smart cards which people use to identify themselves, and determine whether they should be able to access a building (or not). Some of the benefits which RFID offers over the older technologies, such as magnetic stripe cards, is that there is no contact required between the reader and the card. This significantly reduces wear and tear on both the card and reader, requiring much less frequent replacement of card reader hardware. However, cards still need to be protected ideally placing them in a plastic badge holder like the picture below to ensure that the card is not bent and damaged. This article will focus on Passive RFID systems where there is no battery source within the card or credential, as these are more commonly used for access control systems. HOW DOES IT WORK? In an access control installation, the car…

Rewritable card, Save your money
rewrite vb (tr) 1. to write (written material) again, esp changing the words or form
Rewrite, re-write or re write? However you spell it, it still does exactly what it says – it allows you to rewrite a previously printed ID card or name badge. How does rewrite work? The revolutionary rewrite technology doesn’t require any fancy inks or ribbons, but simply uses heat to change the colour of the surface of the card, thus printing any text and images (in monochrome only) – including photographs - on to the surface of the card. Reapplication of heat will then remove the ‘printing’ leaving the card blank and ready to be used again. This allows you to temporarily print on the surface of the card – wiping it clean again when it’s no longer needed. The only way to ‘wipe off’ the print is by running it through the printer again and for a specific temperature to be applied so you don’t need to worry about the image or text fading or disappearing before you’re ready…

Magnetic Stripe Card
Magnetic Stripe Card Any type of card that contains data embedded in a strip composed of iron particles in plastic film. The front of the card contains identifying information, such as the cardholder’s name and the issuing company’s name, while the magnetic stripe resides on the back. These cards are usually a little larger than 2 inches by 3 inches and made of plastic or durable paper. Types of magnetic stripe cards include driver’s licenses, credit cards, employee ID cards, gift cards and public transit cards.
BREAKING DOWN 'Magnetic Stripe Card’ When a magnetic stripe card is swiped through a magnetic stripe reader, the reader decodes the data in the magnetic stripe to enable a transaction to go through. The transaction might allow an employee to access a building or a customer to pay a merchant by credit card. If the magnetic stripe becomes dirty, scratched or demagnetized, the card may not work.

The magnetic stripe on a credit card contains three horizo…

Mini SIM: This SIM card has been around for many years now and can be found on older smartphones or certain feature phones even today. The size of the SIM card is pretty big and if phones like the iPhone 3GS and Nexus 4 are some examples of the phones that relied on the mini SIM card.
Micro SIM: The micro SIM is pretty much the standard these days for the majority of smartphones. Pretty much all Android smartphones at the moment accept the micro SIM as the SIM card of choice. It is noticeably smaller than the mini SIM and has helped to contribute to the creation of thinner smartphones. Phones such as the iPhone 4iPhone 4S Nexus 5 andSamsung Galaxy S5are examples of phones that use the micro SIM.
Nano SIM: The nano SIM is currently the smallest SIM card available at the moment. At one point in time there was a bit of contention between Apple and Nokia regarding the nano SIM in which Apple was looking to make the nano SIM the new standard in SIM cards. The nano SIM is much smaller than …
