The advantage of choosing a primitive polynomial as the generator for a CRC code is that the resulting code has maximal total block length in the sense that all 1-bit errors within that block length have different remainders (also called syndromes) and therefore, since the remainder is a linear function of the block, the code can detect all 2 ...
For example, the widely used (255,223) code can be converted to a (160,128) code by padding the unused portion of the source block with 95 binary zeroes and not transmitting them. At the decoder, the same portion of the block is loaded locally with binary zeroes. The QR code, Ver 3 (29×29) uses interleaved blocks.
The code words are also designed to be delta-decodable, so some code words are redundant. Each PDF data code word represents about 10 bits of information (log 2 (900) ≈ 9.8), but the printed code word (character) is 17 modules wide. Including a height of 3 modules, a PDF417 code word takes 51 square modules to represent 10 bits.
MeCard is a data file similar to vCard but used by NTT DoCoMo in Japan in QR code format for use with Cellular Phones.. It is largely compatible with most QR-readers for smartphones.
MasterCard SecureCode uses OTAC to confirm a user's identity One time authorization code as used in Yammer's desktop client. A one-time password (OTP), also known as a one-time PIN, one-time passcode, one-time authorization code (OTAC) or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device.
When code generation occurs at runtime, as in just-in-time compilation (JIT), it is important that the entire process be efficient with respect to space and time. For example, when regular expressions are interpreted and used to generate code at runtime, a non-deterministic finite state machine is often generated instead of a deterministic one, because usually the former can be created more ...
The Aztec Code is a matrix code invented by Andrew Longacre, Jr. and Robert Hussey in 1995. [1] The code was published by AIM, Inc. in 1997. Although the Aztec Code was patented, that patent was officially made public domain. [2] The Aztec Code is also published as ISO/IEC 24778:2008 standard.
(This particular generator polynomial has a real-world application, in the "format information" of the QR code.) The BCH code with d = 8 {\displaystyle d=8} and higher has the generator polynomial
