ID scanning merchandise can be divided into two fundamental groups: machine readable scanners and optical scanners. Machine-readable scanners decode information saved electronically in a barcode or magnetic stripe and exhibit the information in an simple to study structure. Optical scanners, commonly referred to as optical character recognition (OCR) scanners, take an impression of the card and use computer software to translate the picture into personal computer text. In essence, OCR scanners read through the card as if they ended up a human. Equipment-readable barcode and magnetic stripe scanners are considerably much more exact, more quickly and better at supporting to detect phony IDs than OCR ID scanners.
Precision
Since device-readable ID scanners study the info encoded on the barcode and magnetic stripe of an identification card, they are 100% precise. They show the precise data programmed on the card, including birthday, card expiration, handle, license number, and many others. They use the start day to calculate and display the cardholder’s age, and the card expiration date to establish the card’s position. Importantly, they file the scan details, delivering a trustworthy digital record of age verification. Business proprietors can relaxation certain that their knowledge is 100% exact in situation of a liquor authority raid or company investigation.
On the opposite, OCR scanners are only 98% correct. Since they rely on application to translate an graphic of the card fairly than studying the encoded data, people are often misinterpret and saved incorrectly. Although 98% would seem like a higher share, one in 50 scans has a error somewhere in the information. It could be a mistaken street amount, a negative license variety, or an incorrect beginning day. Imprecise knowledge can produce an incorrect age calculation (if it reads 1969 alternatively of 1989), or render handle info worthless for mailing lists. This assortment of imprecision can make the scan entirely ineffective in an affirmative protection from age verification violations.
For Singapore Fake IC whose goal is defending organization homeowners from age verification violations, the inaccuracy of OCR ID scanners is intolerable.
Velocity
In addition to higher accuracy, machine-readable scanners are also more quickly than OCR audience. The decoding of info from a barcode or magnetic stripe is almost instantaneous. Typical scans take roughly one second to compute and record. OCR scans get upwards of 5 seconds to full because of the enhanced laptop processing necessary to interpret the optical scan.
This small distinction in scan throughput time can have a big influence on ID scanning purposes. Think about a line of one hundred clients waiting to get into a live performance that needs them to be eighteen a long time of age. Let’s believe it takes a bouncer 20 seconds to get an ID card from every patron no matter of the type of ID scanner he is employing. If the bouncer have been employing an OCR scanner, it would consider approximately forty two minutes to examine the IDs of absolutely everyone in the line. It would take the same bouncer only 35 minutes to verify the same line of clients with a barcode or magnetic stripe ID scanner (a savings of 7 minutes). If the line had been 1,000 folks, the barcode/magnetic stripe reader would save approximately a single hour and 10 minutes. This would boost the pleasure of the consumer and reduced the payroll expenses of the enterprise.
Detection of Fake IDs
The most important issue in detecting bogus IDs is an inform operator, and no machine is one hundred% efficient in detecting fraudulent IDs. That currently being said, equipment-readable ID scanners give a massive advantage over OCR scanners in the combat in opposition to phony IDs.
The manufacturing of fake IDs is as dependent upon economics as any genuine company. ID card printers expense about $750 whilst magnetic stripe and barcode encoding engineering adds even far more substantial value. Several men and women that create fake IDs merely are not able to pay for the far more expensive technology needed to encode magnetic stripes or barcodes. As a consequence, bogus IDs are frequently printed on stock ID cards with generic or blank knowledge encoding.
Equipment-readable ID checkers permit the operator to assess the info stored electronically on the ID with the details printed on the card. Faux IDs will frequently have a mismatch in two sets of data. For illustration, the title printed on the entrance of the card could study Charlotte Blake, while the encoded information saved in the magnetic stripe might study John Smith. This is a distinct indicator that the ID is a faux. Even though the machine itself can’t assess the printed information to the encoded details, it supplies a crucial device for any individual trying to verify the authenticity of an ID.
Regular OCR scanners do not obtain the information stored electronically on ID cards. This gets rid of all likelihood of comparing the printed data to the encoded information, and basically renders an OCR ID scanner the equal of a glorified copying equipment. At very best, OCR scanners give a reduced-good quality information entry technique. There are some far more expensive systems which can scan equally sides of the motorists license, read through the 2nd barcode (but typically not the magnetic stripe) and then evaluate the knowledge fields, but these techniques are normally two times as costly, 2 times as sluggish and not suited for retail applications.
Business Card Scanners have the benefit of storing an graphic of the ID card, which indicates they can help save the cardholder image. This is assists build which ID was presented when serving age sensitive items. Even so, if there is a online video surveillance system camera in use when studying the device-readable barcode, then most systems date/time stamp the reads so a retailer can time stamp match the video to the device-readable reads.
Summary
The major downsides of OCR ID scanning engineering are low accuracy, sluggish speed and lack of ability to go through encoded knowledge to detect phony IDs. Fortunately for shoppers, a much more strong age verification resource exists. Machine-readable barcode and magnetic stripe ID scanners are one hundred% accurate, check IDs almost instantaneously, and help to detect bogus IDs.
If you are a business proprietor searching for a way to verify buyer age, which resolution would you choose? The barcode/magnetic stripe reader that speeds by way of prolonged traces, will help decide out fake IDs, and gives a hundred% precision? Or the OCR ID scanner that misreads one in 50 playing cards? Make the wise choice when picking an ID scanner to shield your enterprise, and select a equipment-readable ID scanner.
