About this deal

RFID technology allows businesses to encode data on small chips attached to a plastic card. This can then be used for access purposes, with the card transmitting identification data to an external receiver. Verichip Special Report". spychips.com. Archived from the original on 2012-03-23 .

The majority of RFID Card is still using plastic polymers as the base material. The most commonly used plastic polymer is PVC (Polyvinyl Chloride) due to its durability, flexibility and versatility for card making. PET ( Polyethylene Terephthalate) is the 2 nd most commonly used plastic polymer for card making due to its highly durable and heat-resistant.

The RFID transponder chip ID can be read in more than 50 different ways ( 125 kHz reader, 13.56 MHz reader). It can be read in decimal or hexadecimal format, the sequence of read bytes can be from MSB (most significant byte) to LSB (less significant byte) or vice versa, and even the single bits can be read in multiple ways. ASTM D7580, Standard Test Method for Rotary Stretch Wrapper Method for Determining the Readability of Passive RFID Transponders on Homogenous Palletized or Unitized Loads Paolo Magrassi (2001). "A World Of Smart Objects: The Role Of Auto Identification Technologies" . Retrieved 2007-06-24.RFID tags are widely used in identification badges, replacing earlier magnetic stripe cards. These badges need only be held within a certain distance of the reader to authenticate the holder. Tags can also be placed on vehicles, which can be read at a distance, to allow entrance to controlled areas without having to stop the vehicle and present a card or enter an access code. [ citation needed] Advertising [ edit ] In 1983, the first patent to be associated with the abbreviation RFID was granted to Charles Walton. [15] Each smart card contains an integrated chip with a unique permanent identification (UID) number burned-in during the manufacturing process. This UID is often referred to as the Card Serial Number (CSN). The card serial number is not encrypted and any reader that is ISO compliant can read the card serial number. A sample 10DEC code is 1234567890. If a reader uses an 8H-> 10D conversion, it means that the HEX code is 499602D2. This is a 4-byte code and bytes are 49-96-02-D2. 49 is MSB and D2 is LSB. If a reader would use 8 HEX Reverse Byte format, the reading would be D2-02-96-49 and if converted to Decimal it would be 3523384905. So, after hearing how they work and the benefits they offer, should you buy RFID cards for your business? There are a couple of things to consider before pulling the trigger, so ask yourself the following: Is RFID technology right for our organisation?

Ultra-high-frequency (UHF: 865–928MHz) (Ultra-HighFID or UHFID) tags cannot be used globally as there is no single global standard, and regulations differ from country to country.Often more than one tag will respond to a tag reader, for example, many individual products with tags may be shipped in a common box or on a common pallet. Collision detection is important to allow reading of data. Two different types of protocols are used to "singulate" a particular tag, allowing its data to be read in the midst of many similar tags. In a slotted Aloha system, the reader broadcasts an initialization command and a parameter that the tags individually use to pseudo-randomly delay their responses. When using an "adaptive binary tree" protocol, the reader sends an initialization symbol and then transmits one bit of ID data at a time; only tags with matching bits respond, and eventually only one tag matches the complete ID string.
