NFC Tag UID Encoding

A previous workaround to the issue of iPhone not reading the NFC chip UID natively was to encode the UID as an NDEF text record; the GoToTags Store calls this “UID encoding”. This was useful in the past when the iPhone could not read the NFC chip UID, even via a 3rd party app. However now that the NFC SDKs can read the UID, this method should not be used anymore as it is insecure and easy to clone an NFC tag with UID encoding. All mobile apps should be updated to read from the UID via the SDK instead of from NDEF user memory.
