Do You Feel Used by Computers?

A look at second-user computer equipment.

Let's dispense withrepparttar myths first. I'm NOT talking aboutrepparttar 138480 sort of second-hand computers you get from some high street junk shops, orrepparttar 138481 sort you can buy from free ads newspapers. These arerepparttar 138482 types that get used computers a bad reputation since there are many dodgy deals to be had!

I'm talking about a different breed altogether,repparttar 138483 sort of used computers you'd be proud to own and feel safe buying because they have proper and lengthy warranties on each and every one of them and have been extensively tested and approved.

The criterion is quite strict. Sure, there are any number of companies out there who offer used computers at low prices. Very few offer 12-month warranties however and many of them disappear just as quickly as they arrived leaving you with a problem. All computers, no matter which category they fit in, or what you call them, should be high quality, guaranteed, fully working computers from a reputable supplier.

So, let's put allrepparttar 138484 computers into two categories, I'm going to call them 'used' and 'unused' computers.

1. Used Computers

Second-hand, second user and used computers are what you would expect in that they have had a previous owner. Many ofrepparttar 138485 computers have been returned torepparttar 138486 company from which they were bought inrepparttar 138487 first place. This is ideal asrepparttar 138488 company hasrepparttar 138489 appropriate expertise and spares already in place to correct any faults they find.

There are a number of reasons why computers are returned:

- businesses, colleges, individuals etc upgrade their computer equipment forrepparttar 138490 latest model

-repparttar 138491 equipment was leased over a set period andrepparttar 138492 lease expires (sorepparttar 138493 equipment is returned)

-repparttar 138494 computer gets a fault that can't be fixed quickly so it is swapped permanently out for a new one

-repparttar 138495 customer changes their mind just after purchasing

As you can appreciate, 'used computer' can mean anything from 'barely used' to 'a couple of years old'. However, once returnedrepparttar 138496 computers go through a rigorous check procedure, have their hard disks cleared or changed, have new keyboards, mice and cables if worn and new cases if they have noticeable damage. If there are any faulty components, such as sound card, video card, floppy drive etc, these are always replaced. These computers are often referred to as ex-lease, open-box, returns, refurbished, reclaimed, remanufactured, rebuilt, recycled, recertified or reconditioned computers. Phew!

BIGSquid RFID: Leading RFID Solution in India

RFID (pronounced as separate letters) short for radio frequency identification. It is a technology, which uniquely identifies objects automatically using wireless radio communications.

Radio Frequency Identification (RFID) is a technique of distantly piling and recovering data by means of devices known as RFID tags. An RFID tag is a little object, like a sticky label, that can be integrated into a product. RFID tags hold antennas to facilitate them to accept and react to radio-frequency inquiries from an RFID transceiver.

What is RFID tags? What arerepparttar different RFID tags?

RFID tags are of two types: active RFID and passive RFID. Passive RFID tags don’t have their own power supply. The little electrical current stimulated inrepparttar 138431 antenna byrepparttar 138432 inward radio frequency scan gives adequate power forrepparttar 138433 tag to send a rejoinder. Because of power and cost factors,repparttar 138434 rejoinder of a passive RFID tag is essentially concise. It is normally just an ID number (GUID). Shortage of its own power supply craftsrepparttar 138435 device very small. Commercially accessible products exist that can be implanted beneathrepparttar 138436 skin. The least such devices commercially accessible measured 0.4 mm × 0.4 mm, and thinner than a sheet of paper. Such devices are virtually undetectable. Passive tags have practical read ranges that differ from about 10 mm up to about 5 meters. Passive tags are cheap to manufacture.

Active RFID tags, ought to have a power source, and may have longer ranges and larger memories than passive tags, as well asrepparttar 138437 capability to accumulate additional information sent byrepparttar 138438 transceiver. The smallest active tags are aboutrepparttar 138439 size of a coin. Many active tags have convenient ranges of tens of meters, and a battery life up to several years. Whilerepparttar 138440 cost factors of passive tags over active tags are noteworthy, other factors including accuracy and dependability makerepparttar 138441 use of active tags very common today.

A number of nations have anticipated embedding RFID devices in new passports to ease proficient machine reading of biometric data. The RFID-enabled passport distinctively identifies its holder; inrepparttar 138442 proposal currently under thought,repparttar 138443 RFID tag will also comprise a range of other personal information (More info


BIG Squid RFID is not merely integrating various RFID middleware (tags and readers) with our own products, but we have formed partnerships with other leading companies that enable us to provide supply chain solutions for various clients. BIGSquid RFID provides solutions to various industries like pharmaceutical, manufacturing, textile etc., acrossrepparttar 138444 globe.

BIGSquid RFID is similar to bar code technology by automatically collecting information about a product or transaction quickly, easily and without human error. Lets understand some common differences between RFID and Bar Code.

BIGSquid RFID and Bar code are both identification technologies that hold data that is accessed by some type of reader. In actuality, they complement each other very well and can be used effectively side by side in many applications. Bar code is an optical technology and RFID is a radio technology. However, unlike barcode technology, it provides a contact less data link, without need for line of sight—for example articles inside a cardboard box—or concerns about harsh or dirty environments that restrictrepparttar 138445 use of bar codes. Just like bar code, RFID tags are available with different memory sizes and encoding options. The ways these technologies exchange data account for most ofrepparttar 138446 differences between RFID and bar code and help determine where each identification technology is best put to use.
