Yeah looks like there are lots of confusions on this thread. Here are some clarifications:
1. Chanel has not officially confirmed that they use blockchain technology. LVMH, on the other hand, has confirmed.
2. There’s no way a chip is embedded in a metal plate and still scannable. Metal is an effective electromagnetic shield that can prevent a chip from being scanned.
3. In fact, Chanel has not officially confirmed there is a scannable chip in the bag at all.
4. The only change that has been confirmed so far is the removal of the sticker and card, and the addition of the engraved metal plate.
5. With the information gathered so far, Chanel is only linking the serial number to the buyer upon purchase by simply registering the number in their system. This is something completely new as now they can track the ownership history of your bag. That’s how THEY can ensure a bag is authentic. But since this is internal, buyers and consignment shops will have no way to ensure the authenticity of a bag unless they bring the bag in question to a boutique for registration (change of ownership), repairs or spa services. Chanel does not do authentication in any of their boutiques.
6. We have yet to know what actions Chanel will take when they see frequent changes of ownership in their system, or what they will do when a customer brings a fake bag to the boutique asking for repairs when in fact the customer just wanted to check the authenticity of the bag.
