I am an online seller: do I have to use any special precautions regarding the SOA?

Yes, as indicated in the Terms and Conditions of the service, it is important never to post a photo of the physical smart tag on your site or advertisement. The reason is that scanning or entering the CLG Code initiates an authentication process that can only be completed by whoever physically possesses the product. If you make the CLG Code public and various users initiate authentication without physically having the product, the system reports an anomaly and your customers will not be able to check the authenticity of the product you are trying to sell.
If, on the other hand, you create and publish the SOA, you give all potential buyers the opportunity to check the authenticity of the product before purchasing and you will make your original products more attractive.
