Using Delphi there are several ways you can generate QR codes - to encode any text (URL, phone number, simple message). QR Codes store up to 4,296 alphanumeric characters of arbitrary text.

The 2D Barcode VCL components is a set of components designed for generating and printing barcode symbols in your Delphi or C++ Builder applications. Use the components set like any other VCL components.

J4L Components includes the QR-code implementation featuring: auto, byte, alpha, numeric and kanji encoding.

The Google Chart Tools (Chart API) also let you generate QR-code images using an HTTP POST or GET methods - Generating Qr Codes with Delphi and Google Chart API

	Barcodes         1D         . RBarcode for Delphi supports all major 1D symbologies: Code39,Code39 (Extended), UPCA, UPCE, EAN8, EAN13, EAN128, CODE128,Code           11, Code 93, Code 93 extended, Industrial 25, Interleaved 2 of 5 , Matrix           25, Postnet, Codabar and MSI.
	PDF417.          PDF stands for "Portable Data File." It is a two-dimensional symbology         that can encode more than 1000 bytes of information. It does not need         more space than a traditional 1D barcode. Furthermore several PDF symbols         can be concatenated in order to create a Macro PDF 417 symbol.         RPDF 417 supports: PDF417 Macro PDF 417 Binary, text and           numeric encoding. Truncated / Compact           Macro PDF 417.
	MicroPDF417         is a 2D barcoding symbology based on PDF417. Micro PDF 417 has been         specifically designed to provide even greater space efficiency for small         item marking applications than the standard PDF 417 symbology. RMicroRPDF 417 supports: MicroPDF417, all           formats. Structured append Binary, text and           numeric encoding.
	DataMatrix       is a two-dimensional (2D) matrix symbology which is made up of square       modules arranged within a perimeter finder pattern. It can encode up to       3116 characters from the entire 256 byte ASCII character set.       RDataMatrix supports:          All sizes and           formats (from 10x10 till 144x144) Ascii, text ,           C40 and Base256 (for binary data) encoding. The "Extended           Channel Interpretation and Structured append
	Aztec       code is a 2D matrix symbology made up of square modules on a square       grid, with a square bullseye pattern at their center. Aztec Code symbols       can encode large amounts of data with user defined error correction level.               RAztec supports:         All sizes and           formats. Normal and binary           encoding. The "Extended           Channel Interpretation and Structured append Aztec rune's. Reader initialization           bit.
	Maxicode         is a two-dimensional (2D) and fixed-size matrix symbology which is made         up of offset rows of hexagonal modules arranged around a unique finder         pattern. The size of Maxicode is 1.11 x 1.054 inches and it can contain         up to 93 data characters of information. The symbol was created by United         Parcel Service for fast scanning and sorting of packages. RMaxicode for Delphi         supports the following features: modes 2,3,4,5           and 6. structured append            full character           set
	RSS (GS1       DataBar) and EAN-UCC Composite. This symbology combines a 1D       barcode (RSS or EAN/UPC) used to encode article identification codes and       a 2D component (modified version of PDF417 and MicroPDF417) used to encode       additional information (e.g. best before date).
	QRCode         QR Code is a matrix symbology consisting of an array of square modules         arranged in an overall square pattern. QRCode for Delphi         supports the following features: AUTO, BYTE, ALPHA, NUMERIC           and KANJI encoding.            Structured append            Correction levels           L, M , Q and H Versions 1 to           40 FNC1mode
	Micro QRCode.      Reduced version of QR Code which is smaller and encodes less amount of      data
