Congrats!
This sounds good and there are a few small merchants now adopting Bitcoin as a payment and the good thing is they applied Lightning Network that good for microtransaction for example for a small number of products to purchase. Aside from that, it's totally safe than using a credit card because there's no charge back, make sure at least there's at least 1 confirmation to be done before your customer let leaving at your counter.
and maybe add a link to bitcoin.org in your "bitcoin accepted" signage/website for those who have no idea what it is and wanna learn more.
I like the idea, it seems you're advertising the forum as well.
Below on your QR code device reader, there's a line saying, "
For more info. visit Bitcointalk.org for more details".

This is beneficial for promoting Bitcoin.
Many shops now allow Bitcoin to be used for payment.
There are also many people who noticed the Bitcoin forum and came to the Bitcoin forum to learn,
Everyone in Bitcoin has slowly changed from a novice to an old member.
I have shared this forum with my friends and family. I believe that more and more people will be able to truly understand Bitcoin.
