I started a small business on exporting rice in my town. It's been several months and everything is going well.
All my customers are happy with the service. So to make things a bit more interesting, I've decided to accept crypto as a payment method.
I have designed this business card of mine, and I'll be handing over this to my customers.

In the beginning, I have decided to stick on Binance pay, and BTC payment.
The BTC address is in the QR code on the business card, and also with the PAY ID for Binance.
Universal token transaction will be done through pay ID and BTC could be transferred too.
For those who want to pay with other method, can choose BTC address.
[Note: Information is blurred out for personal reasons.]

I gave it a good thinking and have implemented this in my business. So I want to know you guy's opinion in this.
Feel free to suggest me more secure options and how to improve this.
Thanks a lot in advance.
