Data entry can be done in various ways, including data entry. In data entry, a human agent places data into selected fields of a database using a device such as a mouse, keyboard, keyboard, touch screen, or pen, or alternatively with speech recognition software. Data entry is a type of data entry where there is no data entry. Instead, the data is collected in conjunction with a separate activity.
Personal data stored on a credit card’s magnetic stripe is captured by magnetic stripe readers.
One of the devices involved in this method includes supermarket checkouts equipped with barcode scanners. These scanners are electronic devices that use a laser beam to read a barcode. They are classified as contactless automatic data capture devices and need to be close to the material they are scanning in order to read it.
RFID tags are used in anti-theft devices.
Magnetic stripe readers, also called swipe machines, collect information stored on magnetic material found on bank, charge, and credit cards. This information generally includes an account number, the customer’s own identification number, and other information. ATMs can also read this information. If the magnetic stripe is damaged or exposed to a strong magnetic or electric field, the information cannot be recovered.
Laser barcode scanners can capture data.
A point-of-sale (POS) terminal, through which credit card transactions are submitted and validated, reads the bank name and customer account number from a card swiped through a magnetic stripe reader . If the bank responds that funds are available, the POS transfers the approved amount to the seller’s account, finalizing the transaction with a printed receipt.
Some stores use point-of-sale systems and loyalty cards to capture customer information for marketing purposes.
Optical Character Recognition (OCR) involves converting a scanned image of text created on paper or written by hand into characters recognizable by word processing programs. It is also used to preserve documents in electronic format without the need for manual data entry.
Radio Frequency Identification (RFID) is a data capture technology in which items are identified through transponders attached to them. A transponder is a type of passive radio transmission equipment. Its function is to respond passively with a repetition of the original signal or a coded acknowledgment signal when it receives an initial signal. RFIDs work at greater distances than bar code readers, which is one of their values.
Retail stores have point-of-sale (POS) terminals through which credit card transactions are processed.
