Other features include:
-
Improving consumer experience through enhanced NDEF
-
General purpose counters configurable per event
-
Supports GDPR compliant privacy modes (Kill and Anonymous)
-
Short-distance operation at speeds up to 106 kb/s
-
Dynamically append tag-associated credentials to NDEF for consumer interaction (ANDEF)
To achieve the bridge from physical to digital, the commonly used technologies include QR codes, ordinary NFC tags, and NFC tags based on symmetric encryption algorithms.
These technologies all have certain disadvantages:
QR codes are not secure, affect the appearance, and have no offline data storage.
Ordinary NFC tags have low security/robustness.
NFC tags based on symmetric encryption algorithms require secure storage of keys on the tags and card readers/applications.
Designed for physical product authentication, ST25TA-E can provide value-added consumer interactions for brands, such as better product traceability, prevention of gray markets, and anti-counterfeiting protection. It can also provide consumers with a lot of value, such as proactive self-protection from counterfeiting, product certification and proof of ownership when reselling, and a tailored consumer experience (product level).
