What is a QR code?

A QR code (quick response code) is a type of matrix barcode created in Japan back in 1994 for the Japanese automotive industry. QR codes are a machine readable label via optical scanning which contains information about just about anything you want.

Most QR codes today contain information about a website URL, identifier, address, etc. There are four types of standardized encodings used when generating QR codes (alphanumeric, byte or binary, numeric and kanji).

Does your app have an API (application programming interface) that I can use?

Yes. Using our API, you can create QR code images yourself. We tried to make the API rather straightforward, even for beginners. Here is a list of some of the important features.

• Create QR codes remotely from any website address (develop your own QR code generator).
• Cryptocurrency address format checking to help avoid errors when creating a QR code.
• Protected privacy with encrypted communications via HTTPS (SSL/TLS).
• QR codes with cryptocurrency branded logos.
• High error level correction QR codes to maximize scan reliability.
• Crypto logos automatically resized so they don't occupy more than 12% of the surface area or obscure any data modules partially.

Below are some simple HTML examples of how to use the API with your website or app. For more detailed documentation you can visit our Bitcoin QR code API and widgets page.
