Hello ST Community, I am currently working on an in-house NFC anti-counterfeiting authentication platform for my clothing brand. The system is being built using the ST25TV02KC tag, and we are now in the stage where access to AN5580 – “TruST25 digital signature for ST25TV512C and ST25TV02KC devices” is required to complete our provisioning and backend integration. I have already submitted a request via ols.st.com, but after checking the forums I noticed that many users were informed that access to AN5580 must be coordinated through a local ST sales representative. However, the official contact listed for Mexico appears to be outdated (phone number no longer active, and the physical office shows as permanently closed on Google Maps). Because of this, I am unsure how to proceed or who to contact for this restricted document. Thank you very much for your support.
