// NOTE: local file reads (images, fonts, attachments) are restricted to an allowlist of
// trusted paths that covers this package tree, so run the examples in place. To read assets
// from other locations, list them in the 'allowedPaths' entry of the fileOptions constructor
// parameter (see E047_remote_resources_security.php).
// NOTE: run make fonts in the project root to generate the dependencies and example fonts.
// NOTE: this library encodes the data it is given. Several formats carry a number that only
// its registration body can issue, so a symbol is valid in its scheme only once that number
// has been obtained: GS1 member organisations issue the company prefix used by EAN, UPC,
// ITF-14, GS1-128, SSCC-18, GS1-14 and GS1 DataBar; HIBCC assigns the Labeler Identification
// Code used by HIBC39, HIBC128, HIBCDM, HIBCQR and HIBCAZ; Royal Mail issues the Supply Chain
// ID carried by MAILMARK; IFA GmbH allocates the PZN Pharmazentralnummer; Deutsche Post DHL
// assigns the customer number and street codes of IDENTCODE and LEITCODE; AIFA assigns the
// Italian AIC number encoded by C32.
// NOTE: the symbology names below identify the encoded formats and belong to their respective
// owners: QR Code (DENSO WAVE INCORPORATED); GS1, GS1-128 and GS1 DataBar (GS1 AISBL);
// Mailmark (Royal Mail Group Ltd); Intelligent Mail (United States Postal Service);
// PHARMA-CODE (Laetus GmbH); Telepen (S.B. Electronic Systems Ltd); HIBC and HIBCC (Health
// Industry Business Communications Council); KIX (PostNL); Identcode and Leitcode (Deutsche
// Post DHL). They are used descriptively; no affiliation with or endorsement by their owners
// is claimed or implied. GS1 licenses the claims necessary to implement its standards under
// its IP Policy (https://www.gs1.org/standards/ip) to GS1 members and to the participants of
// the work group that developed the standard, rather than to the public at large.

<h1>Barcode Types Catalog (3/3): Registration Bodies and Trademarks</h1>
<p>Source: tc-lib-barcode README.md</p>
<h2>Identifiers issued by a registration body</h2>
<p>The library encodes the data it is given. Several formats carry a number that only its
registration body can issue, so a symbol is valid in its scheme only once that number has been
obtained.</p>
