How to Use a QR Code to Send Crypto & Bitcoin

Quick response (QR) codes have come a long way since a Japanese company invented them in 1994. They were initially developed to accurately track vehicles and their parts during the manufacturing process, but nowadays companies and businesses use them to identify payment details, login verifications, provide Wi-Fi access, link to a website URL, an app, or contact information, and more.

In this article, we’ll discuss how QR codes work in the crypto industry, and how you can use them to send crypto or Bitcoin upon signing up on Ka.app.

What is a QR Code?

A QR code is a square-shaped grid barcode that contains a series of pixels capable of storing tons of different kinds of data. Yet, even if it stores lots of information, when you scan a QR code, it allows you to access information quickly – hence the name quick response.

QR Code vs. Standard Barcode

Standard barcodes can store only a small amount of information, often in alphanumeric format, while QR codes can store tons of data and can encode alphanumeric numbers, kana, and kanji. Standard barcodes only read from top to bottom or in one direction, unlike QR codes that can read in two directions, from right to left, and top to bottom. QR codes are also easier to read when scanned compared to standard barcodes.

How Does QR Work with Crypto?

A QR code provides a fast, convenient, and secure way to share a wallet address when transferring crypto assets from one device or wallet to another, or when using crypto as payment. You no longer have to copy and paste a wallet address and worry about the risk of losing assets from a simple typo as you can just scan, or screenshot and upload a QR code, to proceed with the transaction.

What are the Benefits of Using a QR Code for Crypto Transactions?

Some of the best things about using a QR code for transferring crypto assets or for sending and receiving crypto as payment are as follows:

  1. It’s easy to share with another user. You just have to screenshot, scan, or take a photo of the QR code to share your information.
  2. It helps reduce transaction mistakes since it enables users to provide their correct payment details or wallet information.
  3. It combines the security of QR technology and blockchain technology.
  4. It speeds up the end-to-end process of crypto transactions since you don’t have to deal with long wallet addresses, network types, and other information.

How to Send Crypto Using a QR Code: A Step-by-Step Guide

Ka.app, a crypto peer-to-peer (P2) payment app, allows you to conduct cross-border crypto transactions in just a few clicks. The first version of the app accepts only four cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Tether (USDT), and the KASTA crypto. But the team is already working on a later version of the app which will accept more tokens and fiat currencies like the Euro and US Dollar.

Here’s a detailed guide on how to send crypto using your Ka.app QR code:

1. Sign up for a Ka.app account.

  1. Download Ka.app from the Apple App Store or Google Play Store.
  2. Open the app and sign up using your name, email address, mobile number, and home address.
  3. Set up your pin code. You would need this to successfully complete a transaction.
  4. Finish the know your customer (KYC) verifications by providing a valid ID and proof of residency.

2. Add crypto into your account.

  1. Log in to your Ka.app account.
  2. Enter the verification code that you will receive in your mobile number.
  3. Click the “Add Funds” button on the dashboard.
  4. Click “Deposit from a wallet.”
  5. Choose the crypto you want to deposit.
  6. Copy your Ka.app address.
  7. Withdraw crypto from your external wallet by pasting your wallet address.
  8. If you don’t have an external wallet, you can buy crypto using a credit or debit card by clicking the “Add Funds” button on the dashboard, and then “Buy with Card.” Input your details and proceed.

3 Ask the recipient to send their the Ka.app QR code, or you can also scan it if you are with them in person.

4. Choose the crypto you want to send.

5. Enter the amount.

6. Enter your pin code to confirm.

7. And you’re done! Wait for the transaction receipt to appear on the screen.

How Much are the Crypto Transfer Fees?

With Ka.app, you can quickly send and receive the same crypto for free. However, the app has a crypto swap engine feature called the Easy Swap Engine which allows users to receive crypto in their preferred currency for minimal transaction fees. This means you can send another user BTC and they can receive it in USDT just by enabling the Easy Swap Engine. The cost would depend on how much and which crypto a user sends, but they’re charged in the source currency.

What Steps Do You Take to Ensure the Safety of Your Users?

Ka.app has two-factor authentication because your safety is our utmost priority. We send users a verification code before they can log in to their account, and they won’t be able to finish a transaction without correctly entering their pin code.

Additionally, Ka.app strictly adheres to anti-money laundering (AML) guidelines and conducts thorough KYC processes to protect its users against illegal activities such as fraud, money laundering, terrorist financing, and more.
