The "Certified Product Database" keeps track of all certifications. Compliance with the Qi specification must be verified by an independent test lab before a product is certified, and may be called "Qi compliant".
In the public Certified Product Database you will not see all 164 certified products. At this moment you will only see 133 product in the public listing. The other 31 products are kept confidential until the product launch. WPC members can see all certified products.
