For those of you who are new to the crypto space we want to give you a brief explanation of what cryptocurrencies are. We also want to give you a short description of what a QR code is and how it relates to crypto.
For the more experienced crypto user we have a quick start guide below on how to use and integrate our Bitcoin QR code generator API.
Cryptocurrencies are virtual or digital currencies designed to work as a decentralized medium of exchange. Crypto is shot for cryptography and is how it secures and verifies transactions.
The amazing math behind crypto is also how it controls the creation of new crypto tokens or coins like Bitcoin for example.
Bitcoins are like digital gold in many ways and just like gold it requires work to "extract" and cannot be created. It must be "mined" via mathematical means.
Bitcoin is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen.
QR codes (quick response codes) are static images made up of squares that are arranged inside a square grid usually on a white background for better contrast when scanning. These codes can be read by devices such as a camera. The data read in these patterns are present horizontal and vertically.
These matrix type barcodes were created in Japan back in 1994 for the Japanese automotive industry. QR codes are simply machine-readable labels via optical scanning which contains information about just about anything you want.
Most QR codes today contain information about a website URL (uniform resource locator), URI (uniform resource identifier), address, email, etc. There are four types of standardized encodings used when generating QR codes (alphanumeric, byte or binary, numeric and kanji).
Converting a cryptocurrency wallet sending or receiving address into a QR code format is an easy way of making or receiving payments. Many cryptocurrency wallets and apps support the scanning of QR codes.
You can create your wallet QR code for scanning by entering a public wallet address into the field above and pressing the generate your QR code button. Once generated you can download it and save it for use on a website or send it to your friends.
Today's projects in the cryptocurrency space have a pretty good incentive to facilitate crypto payments for their users. QR codes helps make this process simple and reliable. All you need is a quick scan from your smart phones camera to acquire the sending or receiving address.
Bitcoin wallet addresses as well as other types of cryptocurrencies are made up of a series of letters and numbers that can be longer than 34 characters. This makes it very inconvenient to have to enter manually by hand each time you need to send or request a payment. So by using our app that long address can be turned into a QR code ready to scan quickly and easily.
There is more to a public wallet address than just the address itself. It also has a corresponding private address (private key) for each of your public addresses. The Bitcoin private key is a random string of numbers that allows Bitcoin to only be spent by the person in possession of this number.
The public wallet address is generated using the private key but it's nearly mathematically impossible to reverse the process and generate the private key only using the public address. Other blockchain cryptocurrency addresses such as Ethereum and Monero work on this same principal and in very similar ways. Usually, the only difference is the address format.
Depending on the type of cryptocurrency and wallet you have, the way to obtain a public wallet address can be different for each one. If you don't yet have a wallet then a good place to start is by getting your first Bitcoin wallet address at bitcoin.org. They even have an easy step by step wizard to help you in selecting a wallet to store your Bitcoin.
The following are the major cryptocurrencies our app currently supports. Use our contact form if you would like us to add your crypto. With enough demand we will be happy to include yours.
Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of Bitcoin is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.
Like other blockchains, Ethereum has a native cryptocurrency called Ether (ETH). Ethereum is digital money. If you’ve heard of Bitcoin, Ethereum has many of the same features. It is purely digital, and can be sent to anyone anywhere in the world instantly. The supply of Ethereum isn’t controlled by any government or company - it is decentralized, and it is scarce. People all over the world use Ethereum to make payments, as a store of value, or as collateral.
Bitcoin Cash brings sound money to the world, fulfilling the original promise of Bitcoin as "Peer-to-Peer Electronic Cash". Merchants and users are empowered with low fees and reliable confirmations. The future shines brightly with unrestricted growth, global adoption, permissionless innovation, and decentralized development.
Litecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Litecoin is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances. Litecoin features faster transaction confirmation times and improved storage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.
Reflecting its mission to fulfill the vision of Bitcoin, the project name represents the “Satoshi Vision” or SV. Created at the request of leading BSV mining enterprise CoinGeek and other miners, Bitcoin SV is intended to provide a clear choice for miners and allow businesses to build applications and websites on it reliably.
Monero is cash for a connected world. It’s fast, private, and secure. With Monero, you are your own bank. You can spend safely, knowing that others cannot see your balances or track your activity.
Dogecoin is an open source peer-to-peer digital currency, favored by Shiba Inus worldwide. Dogecoin sets itself apart from other digital currencies with an amazing, vibrant community made up of friendly folks just like you.
Cardano is a blockchain platform for changemakers, innovators, and visionaries, with the tools and technologies required to create possibility for the many, as well as the few, and bring about positive global change.
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.
Below are some simple (X)HTML examples of how to use the API with your website or app. For more detailed documentation you can visit our API and widgets page.
Enter the following URL into your favorite browsers address bar and you'll get a QR code with a Bitcoin logo and the embedded data of bitcoin:1M5m1DuGw4Wyq1Nf8sfoKRM6uA4oREzpCX
Sample API crypto QR code output of URL above.
Now just replace the example Bitcoin address with your own or change the crypto style to represent the type of cryptocurrency you need to generate a QR code for.
Then you can use the API on your website or app by using the API's URL as the image location. Check out the following (X)HTML markup example.
300 pixels by 300 pixels is the default base QR code size but in the above example you can adjust the image size smaller if needed while still maintaining the image resolution. Just be sure to make both the height and width the same dimensions.
Here are the style names with (X)HTML markup examples and corresponding image outputs for all the current crypto QR code generator styles available.
