npm install -S emvqr
const emvqr = require('emvqr');This is out of the scope of this library. For example, you could use a QR scanner lib in your front end and send the result to your backend. Or if you need test your functionallity, just use a dummy string, like in our example.
const example = '00020101021229300012D156000000000510A93FO3230Q31280012D15600000001030812345678520441115802CN5914BEST TRANSPORT6007BEIJING64200002ZH0104最佳运输0202北京540523.7253031565502016233030412340603***0708A60086670902ME91320016A0112233449988770708123456786304A13A';const result = emvqr.decode(example);
