Most times you have heard of the word direct data entry device, and you keep asking your self what are direct data entry devices. if you are such a person, then having come to this website, that alone shows you are at the right place. but before we go into the meaning and types of direct data entry device, I am going to show you the content or a summary of what you are about to read.

CONTENTS/SUMMARY

1.MEANING OF DIRECT DATA ENTRY DEVICES

2.TYPES AND EXAMPLES OF DIRECT DATA ENTRY DEVICES

3.MERITS AND DEMERITS OF USING DIRECT DATA ENTRY DEVICES.

MEANING ; Direct data entry devices are devices that read data, information or ideas  from a document, or file, or source  and transferred it directly to the computer system. they are different from input devices which depends  on physical interaction which means you’ll have to physically place  or do something to the device for you to receive a result.

EXAMPLES OF DIRECT DATA ENTRY DEVICES.

[1] MAGNETIC STRIP READERS:

magnetic strip readers can be defined or seened as devices that are used to read data from magnetic stripes on identify and banking card. they are mostly used in reading bank cards. you know most times when you go to the bank to make a deposit or some financial transactions you will find out that the cashier or the banker there would take your card maybe debit, credit or visa card or whatever , and they will cross it on one machine, and after a while you will see a receipt coming out from that from the devices, that's an example of a magnetic strip reader. it has been programmed to scan or read data from any bank cards.

MERITS OF USING MAGNETIC STRIP READER

1. It  speed up the rates of business transactions

2. it is efficient and easy to use.

3. it aid the inputs of data into the computer at a faster rate than the normal typing of the data.

DEMERITS OF USING MAGNETIC STRIP READER

1. without electricity it cannot be used.

2. security and safety of files is not totally guaranteed.

3. it has a limited storage capacity, which means it cannot stores larger data.

[2] CHIP READERS

chip readers are mostly used to read data from chips on banks cards.

MERITs

1. it more safer and better than magnetic strip readers

2. it is more secured because the owner can use PIN to protect his or her data.

3. it can store it accumulate large data compared to strip readers.

DEMERITS

1.data can be stolen while entering the pin or personal identification number on the ATM  may be as a result of carelessness or ignorance of the environment.

[3] PIN PADS

Pin pads are used to enter data into Automated Teller Machines, electronic funds,transfer at point of sales (POS)system,entry doors and hand held devices.

MERITS

1. do you Know that your PIN codes help prevent  unauthorised access.

2. it also help in the safety and security of  entry doors without being accessed with any other physical key cards.

DEMERITS

1. one thing i have notice  in life is that every thing that has an advantage it also have  a disadvantage. Do you know that while entering the code, anyone with the correct code can use the device, 

2. PIN can be forgotten and if forgotten it cannot be accessed again.

[4] RADIO FREQUENCY IDENTIFICATION (RFID)

Radio frequency identifications are technology devices that are used to read data wirelessly from RFID Chips or tags using what is known as an electromagnetic field as it medium of transfer.

[5] MAGNETIC INK CHARACTER READERS (MICR)

Magnetic ink character readers are used to input data's from banks cheques.

Benefits/uses of Artificial intelligence

[6] OPTICAL MARK READERS (OMR)

Optical mark readers are devices that are used to read and informations from a firm, class register or test papa /examination answers scripts.

ADVANTAGES: whole pages of information can be read very quickly, small marks required

DISADVANTAGES: incorrectly completed forms can result in errors, characters or numbers cannot be read.

[7] OPTICAL CHARACTER READERS (OCR)

Optical character readers are devices that are used to transfer handwritten or printed text documents in an editable text format on a computer system.

[8] BARCODE READERS

Barcode readers are devices that are used to scan identification codes directly from products,books,and membership etc.

ADVANTAGES: faster, more accurate than manually inputting data, barcodes are used internationally to identify the product
