I was really happy with my Kong cash (earlier project by same creators) and handed it out as gifts. It really does look and feel like money from the future. The wallets associated with my bills becomes unlocked october of this year, but I don't suppose the ERC20 Kong token is worth much atm. I thinking locking up mBTC makes a lot more sense - any reason you went with creating your own token the first time around ? Has BTC caught up with ETH in some matters of programmability ?

Thank you, the Kong Cash notes were a labor of love and are now very limited in availability -- glad you got some! With Kong we wanted to create a completely new cryptocash from the ground up with Kong with the idea "what if a cryptocurrency started physical first". It was really a demonstration of the usefulness of secure element chips that generate their own keys -- work we've continued with Kong Land. Unfortunately the chips we use for Kong Cash rely on the P256 curve rather than secp256k1. With Ethereum and the EVM we could bridge this via smart contract, however, Bitcoin script is too limited to achieve the same result (imo with good reason). We landed on a very different chip configuration for Bitcoin which has the tradeoff of some centralized elements, but also allows the user to introduce their own entropy (unlike the chip we used in Kong Cash which in theory has very good entropy, but still relies on claims from the manufacturer). The timelock concept from Kong, however, works incredibly well for the Bitcoin Note as a failsafe for conditions where we disappear or refuse to service notes.

I was thinking isn't it exactly the same as kong and yet there are no other mention of it other than this reply. I wonder if they have an office in Hong Kong or something.

  IIRC they were based in Shenzhen (across the bay from HK), I only knew of the connection because I am on Kong Cash's mailing list.
