	"giautm.dev/sgqr"
	qrcode2 "github.com/lizebang/qrcode-terminal"
	"github.com/skip2/go-qrcode"
)

func main() {
	i := &sgqr.VietQRInput{
		AcqID:          "970415",
		AccountNo:      "113366668888",
		Amount:         79000,
		AdditionalInfo: "Ung Ho Quy Vac Xin",
	}

	payload, err := i.BuildPayload()
	if err != nil {
		panic(err)
	}
	fmt.Println("Data", payload)

	qrcode2.QRCode(payload, qrcode2.BrightWhite, qrcode2.NormalBlack, qrcode.Medium)
}
