Aztec Code How QR codes (and other 2D barcodes) work - Explain that Stuff Tweet by Chris Woodford . Last updated: July 2, 2016. From buying groceries to tracking a UPS delivery, barcodes make our lives easier in all kinds of ways—but they've been doing so now for decades. Originally patented in the 1940s, barcodes were commercially tested in the 1960s and gradually became ubiquitous in the 1980s.

The basic idea has barely changed in all that time: just like in the 1960s, a barcode is still a zebra pattern of stripes with numbers written underneath that needs a special scanning device to decode it. But all that could change soon as the 2D barcode—a kind of second-generation barcode technology—slowly takes over. Let's take a closer look at how it works! Photo: Do-it-yourself postal systems, such as Royal Mail's SmartStamp® (in the UK) and Deutsche Post's Stampit (in Germany), let you print your own franking labels on parcels without the bother of going to a post office. They print a 2D barcode on the postage label to validate it and protect against fraud. The code is read and checked when the mail passes through automated sorting equipment. This is an example of a data-matrix code made from four separate segments. What are 2D barcodes? You might have already noticed odd black-and-white squares appearing on your parcels, letters, utility bills, T-shirts, product packaging, and in all kinds of other places— a bit like mini crossword puzzles without any letters.

They're called two-dimensional (2D) barcodes and, just like ordinary barcodes, they're machine-readable so they can quickly pass on information about a product in the blink of an electronic eye. Where a barcode presents a string of information as a one-dimensional line of black and white bars, a 2D barcode packs a lot more information into a grid of black and white, square-shaped dots. Photo: It's a great idea to turn your website address (URL) into a QR Code® and put it on all your promotional material—from advertisments and leaflets to T-shirts and delivery vans. Here's a QR Code being used to good effect on a promotional leaflet from the Swanage Railway. If I want to find out more, all I have to do is point my cellphone at the leaflet and click. Be careful how you print the code: although there's some tolerance for bad printing, it still needs to be printed reasonably clearly and accurately or it won't work. So crisp laser printing is fine, but smudgy inkjet prints probably aren't. Always test the final, printed code with a QR Code reader to make sure it takes you where it should! What are the advantages of 2D barcodes?

If we already have barcodes, why do need something else as well? 2D barcodes are a step further, with lots of advantages: More information: A barcode is just a short line of black and white bars so it can't contain much information: typically just a dozen digits or so—enough to identify a box of cornflakes to a grocery store checkout, but not much more. You can't add extra information to a barcode without making it longer and more unwieldy. By contrast, a 2D barcode is a square of information running in two directions so it can efficiently pack more information into the same space. A typical 2D barcode can represent up to about 2000 characters of information. Fewer errors: Barcodes hold so little information that there is very little redundancy. Apart from the length of the bars (which effectively repeat the barcode's information in the vertical direction), there is no duplication of information to guard against a code being misprinted or damaged (such as when a grocery box becomes torn in the store or a parcel label smudges in the rain). But the higher capacity of 2D barcodes means they can hold the same information in different ways with sophisticated, built-in error checking systems.

If a code is damaged, that's easy to detect—and it may still be possible to read some or all of the code. Easier to read: 2D barcodes can be read by smartphones and tablet computers using their built-in digital cameras . No special reading equipment is needed. Even though they contain more information, they can be read accurately at high speeds. Easy to transmit: 2D barcodes can be sent as SMS text messages between cellphones. More secure: It's possible to encrypt the information in 2D barcodes to protect it. What are the different kinds of 2D barcode technology? To an untrained eye, 2D barcodes all look much the same. Look more closely, though, and you'll see they do vary quite a bit. There are actually several different types of 2D barcode, some available in the public domain and some that are still proprietary.

The best known include QR Code® (pioneered in the 1990s by Japanese company Denso-Wave), Aztec code (developed by Welch Allyn and recognizable by a distinctive square "bulls-eye" pattern in the center), MaxiCode (used by the US postal service, and featuring a round "bulls-eye" center), and Semacode—though there are literally dozens of others. Data-matrix code is the name of the international (ISO) standards covering 2D barcodes, but not all 2D barcodes comply with them (Semacode does; QR codes and Aztec codes are slightly different). Photo: Two examples of 2D barcodes: A QR Code on the left and an Aztec code on the right. Both contain the address of this website ( but look how very different they are: there are many different ways of encoding the same basic information in a 2D data matrix pattern. What information does a QR code contain? By their very nature, QR codes (and other data matrix codes) are meant to be read by machines, not humans, so there's only a certain amount we can tell just by looking at them.

Although each code is different, they contain a few interesting, common features. Looking again at the explainthatstuff.com QR code up above, we have: Quiet zone: An empty white border that makes it possible to isolate the code from among other printed information (for example, on a dirty envelope, among the black and white print of a newspaper, or on smudged product packaging). Finder patterns: Large black and white squares in three of the corners make it easy to confirm that this is a QR code (and not, say, an Aztec code). Since there are only three of them, it's immediately obvious which way up the code is and which angle it's pointing at (unless the code is partly obscured or damaged in some way). Alignment pattern: This ensures the code can be deciphered even if it's distorted (viewed at an angle, printed on a curved surface, and so on). Timing pattern: This runs horizontally and vertically between the three finder patterns and consists of alternate black and white squares. The timing pattern makes it easy to identify the individual data cells within a QR code and is especially useful when the code is damaged or distorted.

Version information: There are various different versions of the QR code standard; the version information (positioned near two of the finder patterns) simply identifies which one is being used in a particular code. Data cells: Each individual black or white square that's not part of one of the standard features (the timing, alignment, and other patterns) contains some of the actual data in the code. Artwork: Above: Some of the key features in a QR code. Below: Features like this ensure a code can be read at high speed even when it's viewed at an angle, smudged, printed on a curved surface, or distorted in various other ways. Further reading There are a number of other features and complications that I won't go into here; if you'd like more detail, you'll find it by looking at these two excellent references: QR Code Tutorial : A very good explanation of how a QR code works, in theory and practice.

What is 2D barcode technology used for? Photo: Using an iPhone as a mobile airline boarding pass. This is an app called MeeTicket that lets you store and display airline boarding passes from different airlines. Photo: A data matrix code engraved onto a Space Shuttle part. Photo courtesy of NASA. The American space agency NASA was one of the earliest organizations to make widespread use of data matrix codes, in the mid-1980s: it engraved them onto parts from space rockets , such as the Space Shuttle, because they didn't come off, like paper labels, and could store so much more information. You can put a 2D barcode anywhere you can put a barcode (software for generating codes is easy to find online) and use it in very similar ways for tracking and tracing all kinds of objects. Cellphones with built-in 2D barcode readers are leading to other, more exciting applications. Advertisers who want you to find out more about their products online simply print a 2D barcode in the corner of their ads.

Just point your cellphone at the code, scan it in, and your phone browser will automatically read the code, decode the Web address of the advertiser's site, and take you there instantly—no need to type in a tedious URL (website address) or anything like that. It's especially convenient for billboards, posters, and other ads you catch site of while you're on the move. Transportation is another increasingly popular application. Numerous airline, railroad and bus companies let you buy travel tickets online in advance and store them on your cellphone. Your phone displays the details on its screen as a 2D barcode code, which becomes your electronic ticket (and, in the case of airlines, your boarding pass. German airline Lufthansa's Mobile Boarding Pass is an example.) Expect to see lots more 2D barcode applications appearing very soon! E-commerce Books Barcodes for Mobile Devices by Keng T.

It's packed with features and the interface is very polished. And there are no ads. The only things missing are the ability to backup saved codes to the cloud (preferably Google Drive, if the dev is reading this 🙂) and support for Android Marshmallow permissions. But those are tiny quibbles. I highly recommend this app. Mark Poole The best available! Love this app! Stores all my barcodes. Shopping cards, loyalty keytags, library cards, ID badges, etc. Plus no permissions; so I know they aren't anywhere but on my phone. Being able to manually enter a number was a lifesaver for cards I've long since lost but could look up the numbers of. Wish I could resize the barcode inside the app (too big to scan sometimes), but that's a minor complaint. didgitalpunk This is the best scanner/ creator for android. Scans almost instantly, has no stuide animations to it, it just fricking works. One good addition to it would be a thorough description of each code type, how it's read and decrypted. (Wikipedia has some pretty good info on at least QR and Aztec, but it's annoying to have to open Internet to see that).

Ryan Smith Works like a charm, best available IMO! You should really be charging for this! Relentlessly searched play for separate good reader & generator and found both in this app. Works flawlessly on my rooted Nexus 5 running MM v6.0.1 MMB29K. Would love some changeable error correction levels, different app colour scemes & scan image files but that's small beans. More 2 come? Priscilla Achampong Simple. Powerful. Almost Perfect. Great app, the only thing missing is security verification. A notification after scanning a code which tells users if the link or data they click on is safe or malware. Possibly a name change too seeing as the app can also scan codes as well as generate them. Thanks. James Brown Perfect for sharing your info I've been searching for a cross platform way to share contact info. This is the perfect solution.

It is doesn't open code address or code location or code website or any thing! Full Review Ray Luo March 21, 2016 It supports lots format, without AD, and it has small size. However, all the info needs to be manually input. That is inconvenient. For example, when inputting location, it would better support choosing a location from map; when inputting contact info, it would be better to choose from contact. Full Review Supaat Tohir Waras May 23, 2016 Need security verification.

Still get 5 stars, just wondering if there is a way to share multiple bar codes. Full Review ;Chris Cinelli July 14, 2016 Work well but... I just would like that it could show the barcode type in the summary and give you a quick way to change it in edit mode with a preview of the code. Sometimes I do not know the code type and I try to recreate entering the number and comparing visually. Also can you please add an export/import feature? Full Review December 8, 2016 Awesome App! Now I can generate codes using my phone ~vs~ PC anywhere! Tried several others but this is the BEST! Quick & easy too! The best part....

NO ADS & TOTALLY FREE!!! 👍👍👍👍👍 Full Review Jason Richards November 17, 2015 Used to be awesome Can you please bring back the ability to change code type rather than having to set up a new barcode and type the number every time you want to change types. I shouldn't have updated Full Review Yunzhao Xing January 9, 2016 If it is possible, please add size adjusting function. Its idea is great, i was looking for it for long time. But the size of generated bar code is fixed. My cell phone has big screen, so the bar code generated is too big to be scaned. Full Review Will D September 28, 2016 Very good I use it for items that don't have a barcode sticker I can just use my scanner to scan my phone screen very good for that. Full Review Justin Diebolt September 14, 2016 Great app. I love how minimalistic this is. Great work! The only issue I've encountered is sharing directly from the app itself. I'm using a Galaxy S7 running Marshmallow 6.1 - with the sharing aside, awesome app!

This is good reccomend for code scanner and ganerate. Full Review Alex Nakatani June 12, 2016 Great app! Great for blind people like me, if you have a hard time seeing this barcode scanner can help you by scanning the code so you can actually read what it is if the code is too tiny! Lol! Full Review Luca Iremadze December 1, 2015 Thank you for this high quality app! I would just like to make a suggestion, the barcode scanners can't seem to scan my stored cards without a handheld scanner.

I would like to use this with the stationary scanners which seem to be programed to scan small size barcodes. In app barcode resize? (I did have full brightness) Full Review Siacri Six March 5, 2016 What the hell? No 10 digit code?apparently not catering to americans (based on the names of the 5 star ratings with no comments i must assume thats why my codes arent scannable or functional when entered manually) Virtually everything we need to generate is based on a 10 digit code..so whats up with this? Sure it scans them and does nothing..giving it 2 stars for benefit of the doubt given it works for others but it doesnt apply to our products at all..it just sits there..with a big exclamation point like i'm missing something...yeah..i'm missing the functionality and apparently at least one number on the barcodes of the products..hmm Full Review Nathan Harvey July 6, 2016 The most genius ever This app does more than advertised: you can scan barcodes (including boarding passes), then save them to a list and pick from that list once you arrive at the gate.

If your airport doesn't support mobile passes, well now they do! :) you can also save some membership cards this way. Would someone please add the fact that it can scan to the description?

Connecting the Dots: An Introduction to 2D Barcodes - Masabi Share Connecting the Dots: An Introduction to 2D Barcodes As the growth of sophisticated mobile devices becomes ever more pronounced in modern society, barcodes are beginning to emerge as a new channel through which these devices communicate and relay information for us. While conventional 1D barcodes have existed on everyday consumer items for some time, we are now beginning to see 2D barcodes surface as a common feature of the world around us. You can now see them on movie posters, pay for your coffee with them, or even use them as a train ticket. Therefore, in order to make the most use of this new technology, a basic understanding is very advantageous.

You may also like to read a Case Study of Mobile Barcodes in use in the UK A Brief History of Barcodes Barcodes, in their 1D format, were first developed in the rail industry to label railroad cars for automated tracking. They achieved commercial success in the 1990s, when they were adapted to be used on consumer goods such as supermarket food items. Since then, their influence has spread to encompass virtually any identification system that can be processed by a machine. A common 1D barcode known as EAN-13 How Do Barcodes Work? In simple terms, barcodes are a visual language that is recognised by computers. In other words, a scanner reading a barcode is like a person reading a sentence. Since computers process binary data, every line or pixel in a barcode represents a 1 or a 0. After scanning, the lines or pixels are ‘translated’ by the computer into binary data, a series of 1s and 0s. Crucially, all barcodes contain an error detection system (the check sum in the image above). This ensures that a barcode will be rejected if it cannot be read correctly (e.g. due to damage or tampering).

It works like this: after scanning the code, the reader performs a simple check sum (mathematical calculation) over the 1s and 0s of the message, and compares this value to the check sum within the barcode itself (which was calculated before the barcode was generated) – if they do not match, the scan is rejected because some of the 1s and 0s in the message must have been changed. The Leap to 2D 2D barcodes, which are now becoming more prevalent in our day-to-day lives, are a more sophisticated evolution of their 1D variant. Whereas information on a 1D barcode is stored and read horizontally only, 2D barcodes store information both vertically and horizontally. The lines of a 1D barcode thus become dots, or pixels, in 2D. Consequently, 2D barcodes are able to store much more data and communicate much more complicated tasks within a smaller physical area, though obviously they require enhanced scanning equipment.

The numbers 1234567890 encoded into EAN-13 and Aztec formats; red lines indicate scanning axes Barcode Symbologies There may not appear to be much of a difference between any two barcodes, other than cosmetic, but there are actually hundreds of types, and they each require a specific symbology to be able to decode them. These different types are each developed to suit a specific role or industry. Each barcode symbology comes with a specification, which is a technical document that explains how that barcode pattern is displayed, how it functions, and how it must be printed in order to be properly decoded. Barcode readers in different forms. They can also be mobile phone cameras or embedded in large machines e.g. ticket gates at stations What is a Symbology? To extend our analogy of a machine language, a barcode symbology can be seen as a language ‘dictionary’ for a specific type of barcode. It tells a reader (which can be either a laser scanner or a digital camera) how to read the barcode, and decode the squares into data. Common types of 2D barcodes include Aztec, Data Matrix and QR Code.

While they all look similar in appearance, each one is encoded in a different ‘language’. So, for example, just as we can read this sentence in English, a scanner installed with the QR symbology can read a 2D barcode encoded with the QR symbology. However, without the appropriate symbology, the scanner would not be able to decode a Data Matrix barcode, just as we would not understand this sentence if it were written in, say, Swahili: we would recognise the letters, but not be able to extract any meaningful information from the sequence in which they are placed in the words or sentence. Error Correction Just as in 1D barcodes, each 2D symbology includes error detection. More importantly though, 2D symbologies also contain error correction measures to make sure that a barcode can still be read and all its information captured, even if an error is detected. Human brains have similar error correction, for example if you cover up the bottom half of all the letters in a sentence you can still read the words without too much trouble. The barcode provides enough redundant information and mathematical encoding to reconstruct the original information even with significant chunks missing. E.g.

Like the words above, a damaged barcode can still be read perfectly well Proprietary and Non-Proprietary Symbologies So, in summary, to be able to scan a barcode, we must have the symbology in which it is encoded, and as we have said, there are many different types. These types can be sorted into two categories: Non-proprietary – the symbologies of these barcodes are public domain, and so are freely available to anyone. They are also regulated by various organisations to ensure they have a standardised specification and are suitable for commercial use. QR, Aztec and Data Matrix are all examples of non-proprietary barcodes Examples of non-proprietary barcodes all containing the same information (the text from Proprietary – these symbologies are privately owned and developed, so they can only be decoded by software that is owned or licensed by the company that owns the symbology. These are usually developed by companies to suit a specific purpose. The Rise of the QR Code One of the rising technological trends in marketing recently has been the appearance of the QR barcode. The QR barcode was first used commercially in Japan in 2002 by the mobile phone manufacturer DoCoMo.

Since they controlled the vast majority of the handset market, they were able to introduce QR barcode scanning support on all of their handsets, and QR barcode use expanded very quickly. A typical user experience would be to take a picture of a barcode on a movie poster, and then the encoded data tells the phone to take you to the movie’s website. Now that the technology has come to the West, this currently seems to be the sum of most people’s experiences with 2D barcodes, and consequently, we as consumers are only aware of half of the 2D barcode’s true value. QR vs. Aztec The essential difference between the more common QR code and Aztec is that QR codes are better for being read by consumers’ phones. Aztec, however, is better for being displayed on consumers’ phones – essential for high-speed scanning in a busy transport environment. Aztec barcode train tickets on small, medium and large screen devices Although QR and Aztec codes can both support text or binary data, at different sizes, it’s how the scanner understands how to read each symbology that makes them different.

The most noticeable aspect of this is the positioning of the finder pattern – the squares that allow the scanner to find and orient the barcode, adjusting for any skew, scaling or rotation and interpreting the pixels accordingly. For QR, the reader needs to see all four corners of the barcode because the finder pattern squares are placed in three corners. Additionally, QR (and Data Matrix) barcodes need a quiet zone – an area of white around them to distinguish them from their surroundings – so that the scanner can clearly read the finder pattern in the corners. The red arrows indicate the finder pattern squares, which are always in the same three corners For Aztec, however, the finder pattern squares are placed in the centre, which means that the scanner only needs to see the centre of the barcode clearly to orient it. This is because the user might misalign the corners of the barcode when turning the screen away from them and towards a reader. As a result, all the user needs to do is put the phone screen roughly in the centre of the reader to scan the barcode. This gives Aztec faster scan times with fewer problems, making it ideal for mass-market use as a mobile ticket.

Moreover, because the finder pattern is in the centre, Aztec barcodes do not need a quiet zone. This means that even on phones with a small screen (where the barcode fills the entire screen), Aztec barcodes can be displayed and scanned properly. Even surrounded by a colour that may confuse a reader (e.g. the black frame of a phone), the barcode can still be read Conclusion In conclusion, we can now say that barcodes are not simply a series of bars or dots, but are a complicated and diverse set of machine languages, many with specific uses and some that suit more general purposes. They are a visual, encoded representation of binary data that can be read by computers and translated into code or text, and include built-in measures for error detection – and in the case of 2D, error correction – to safeguard against damage, tampering or improper scanning. We can classify them according to dimension (i.e. 1D or 2D), their symbology and whether they are proprietary or non-proprietary.

It can encode the full ASCII character set in a symbol which consists of multiple rows of Code 128 type symbols, using a common “Start A” start character and a common “Stop” stop character. Apart from the start and stop character the other characters in adjacent rows have a horizontal line between them. Each row in a Codablock symbol contains (in addition to the common start and stop characters) a subset selector, a row indicator and a check digit, along with a number of data characters. This enables each row to be read by Code 128 scanners. Codablock symbols can hold a maximum of 2725 characters, although this value is significantly reduced by the presence of subset change characters.

Codablock symbols can have between 2 and 44 rows, and each row can hold between 4 and 16 characters plus the subset selector, row indicator and check digit. Codablock symbols are character self-checking and may be scanned in any direction. The subtypes used in the symbol are essentially identical with those use in Code 128 symbology. Code 16k barcodes Code 16k barcodes are stacked barcodes which encode characters using a reverse video version of Code 128. Each row starts and ends with a UPC digit, which indicates the row number and the direction of scan. Each row encodes 5 data characters and the Code 128 type C mode is used for numeric-only strings. A maximum of 16 rows are permitted. Code 16k has three coding schemes and permit the inclusion of special characters not present on the keyboard. If no coding scheme is specified scheme B is used by default. Scheme C is used for any code, which has numbers in the first four digits.

An alternative scheme may be selected within dLSoft products by selecting one of the following Start modes: Start mode Code 49 barcodes A code 49 barcode is a stacked symbol containing between 2 and 8 rows, each separated by a separator bar. Each row contains 16 “words” (which are generated from character pairs) and a start and stop character. The last row also contains the number of rows in the symbol and the check digit characters. There are 2400 possible words which can be generated from each pair of characters (by taking the value of the right hand character plus 49 time the value of the left hand character). Symbols with less than 7 rows contain 2 check digits in the final row. Symbols with 7 or 8 rows contain 3 check digits in the final row. A numeric mode allows 5 digits to be encoded in the same space as three alphanumeric characters, so offering a higher density. Encoding Code 49 symbols may be accomplished only in Auto mode and there is no user choice in the number of rows or columns in a Code 49 symbol. Maxicode symbols MaxiCode is not really a barcode – it doesn't have any bars.

It is a fixed size matrix symbology made up of offset rows of hexagonal modules, with a Finder pattern in the centre. MaxiCode symbols are reproduced at a width of 25.5 mm and a height of 24.4 mm (in each case there is a tolerance of 1.5 mm). Intended primarily for encoding addresses for postal and delivery applications, it has a relatively low information content. On the other hand the fixed physical size of the image simplifies the facilities required for both printing and scanning the symbols. MaxiCode is characterised by the two "messages" which make up its data content – the Primary message and Secondary message. The symbology may be used in 5 modes which utilise the two message in different ways and with different levels of error correction, as shown in the table below: Similar to 4, but used for reader control. In modes 4, 5, and 6 virtually any ASCII data may be encoded up to the maximum number of data characters allowed. However, encoding introduces additional shift and latch characters whenever characters other than uppercase letters and numbers are used and the maximum length of text becomes correspondingly smaller.

Modes 2 and 3 are for Structured Carrier Messages and require specific data in the correct order to produce a scan able symbol. Basically the data consists of the sequence: postal code G country code G service class G secondary message where the 4 components are separated by ASCII 29 characters, shown as G. In mode 2 the postal code must be numeric only and up to 9 digits. In mode 3 the postal code may be up to 6 alphanumeric characters. The country code and service class elements must be three digits each. Mode 2 or 3 message which begin with the sever character sequence [)>R01G (where G is ASCII 29 and R is ASCII 30) are treated in the special way described in the MaxiCode specification. Any secondary message can terminated with an End of Transmission character (ASCII 4).

Because the non-printable ASCII characters are a required part of MaxiCode messages in Modes 2 and 3, dLSoft software recognises the following keyboard sequences for the entry of such characters: Sequence 2D Aztec Barcode Tutorial | IDAutomation Verifying Aztec Barcodes Printed barcode symbols may be easily verified with the Print Quality Assessment feature available in the IDAutomation 2D Barcode Scanner . This quality assurance test will grade the symbol and report any possible problems. The report below was generated when scanning the symbol at the top of the page with PQA enabled: >> PQA << AZTEC CODE: 3 layers (Compact) => 23x23 modules Data Field: 32 data & 19 checks in GF(256), 0 Erasures & 0 Errors X roughly = 0.020" [A] < Core Symbol: 0 errors [A] < Data Safety Margin = 113% [A] < Horizontal Print Growth = +11% of X [A] < Vertical Print Growth = +14% of X Reading Aztec Barcodes The most common method of reading Aztec barcodes is with a camera-based barcode image reader.

Most 2D barcode imagers available at IDAutomation perform keyboard emulation and receive power from the USB port so that no external power supply is needed. When a barcode symbol is read using keyboard emulation, the data appears at the cursor as if it had been typed in from the keyboard. Most 2D barcode imagers have the ability to read Aztec barcodes by default. Many hand-held imagers also read very small symbols such as the IDAutomation 2D Barcode Scanner , which reliably reads Aztec barcodes printed as small as 3 points, which is an X-dimension of 10 mils. In many cases, there may be a need for the scan to trigger a form or action within an application. IDAutomation has documented simple methods of accomplishing this task in the USB Barcode Scanner Application Integration Guide . ASCII Function Encoding Aztec allows ASCII codes to be encoded for various functions such as tabs and returns. In all IDAutomation products, the tilde (~) may be used to encode ASCII functions. For example; ~d009 is used to encode a tab and ~d013 encodes a return. In many development environments, Chr or Char may also be used to encode the ASCII value directly.

For example, the programming examples below encode "ECC" <tab> 200: Java: DataToEncode= "ECC" + (char)9 + "200"; Visual Basic: DataToEncode= "ECC" & Chr(9) & "200" It is possible to scan and encode international and extended characters with these steps: Encode the data using byte encoding. Scan the data via the serial interface option (data bits have to be 8N) on the scanner. Normally, keyboard wedges and USB scanners do not support extended characters above ASCII 128, and only scan characters that are actually on the keyboard. Contact the scanner vendor for more information as some of the scanner's internal settings may need to be changed. Encoding Modes & Error Correction Products such as the IDAutomation Aztec Barcode Fonts and the Aztec Barcode Components all support automatic encoding mode. The error correction level encoded in the symbol is specified as a value from 5 to 95. More error correction creates a larger symbol that can withstand more damage. The Aztec Forms Control supports the following encoding modes. Auto is used to automatically switch between encoding modes, as needed, to provide the most efficient symbol.

Byte is used to encode data strictly byte. Text is used for only letters, numbers, and punctuation. Numeric is used for only numbers. It is not recommended to use error correction over 23 with large amounts of data, because this may overload the symbol capacity. The default setting of 0 performs the automatic and recommended selection, which is usually a value of 23. Control Characters and use of the Tilde IDAutomation Aztec Barcode Fonts , Components and Applications use the tilde character "~" to recognize special characters when "Apply Tilde" or "Process Tilde" is enabled. The following tilde options are available: ~dNNN: Represents the ASCII character encoded by the 3 digits NNN. For example, ~d009 represents a tab, ~d013 represents a return and ~d065 represents the character 'A'. ~1: Represents the character FNC1. When FNC1 appears in the first position (or in the fifth position of the first symbol of a Structured Append), it indicates that the data conforms to the UCC/EAN Application Identifier standard format.
