Can I use TDNs now?
No. This is only a project propossing a technical solution for Central Bank Digital Currency (CBDC). When talking about Digital Currency it is taken as a fact that it is some form of crypto currency, blockchain, distributed ledger or account with the Central Bank. Transferable Digital Notes (TDNs) are not based on any of these technologies. Putting in circulation Digital Currency is a very complex process with legal, social and economic implications. Central Banks all over the world conducted studies to evaluate different technologies for implementing CBDC. As you read this, no central bank has implemented CBDC.
TDNSYS Project is an effort to bring to the attention of financial institution the advantages of using TDNs as a replacement for paper cash.
What is Central Bank Digital Currency (CBDC)
Should be understand that CBDC is mostly an idea or concept and at pressent there is not such currency in existance. According ot Wikipedia:
Central bank digital currency (CBDC, also called digital fiat currency or digital base money) is the digital form of fiat money (a currency established as money by government regulation or law).
Central bank digital currency is different from virtual currency and cryptocurrency, which are not issued by the state and lack the legal tender status declared by the government. As such, public digital currencies could compete with commercial bank deposits and challenge the status quo of the current fractional reserve banking system.
Is TDNSYS based on blockchain?
No. Transferable Digital Notes (TDNs) are based on existing, proven database and networking technologies. Paper money as a legal tender is under the control of the Central Bank implying that a Digital replacement for Paper money has also to be under the control of the Central Bank it replicates all the properties of paper cash excluding any distributed technologies like blockchain or distributed ledger.
Do I have to be "computer literate" or "computer savvy," in order to use TDNs

Can I invest in TDNs?
Do not confuse TDNs with Cryptocurrency. TDN is cash. Holding (or hording) TDNs is like keeping paper money under the mattress. It loses value with time due to inflation.
What is double spending?
When you give somebody some paper money obviously you are no longer in the possession of that money. The problem with digital assets is that they can be copied. For example, if a software program is protected with a key it is possible to copy the key and use it again. To prevent this, software companies require software registration. After the registration the key cannot be used again. When using digital tokens as a replacement of money a mechanism must be in place to prevent using the same token again after a payment was made. This problem is called Double Spending.
TDNSYS prevent double spending using a patented method. After receivin a TDN the new holder has to connect to the Central Bank TDNSYS and request ownership of the TDN.see Get TDN Ownership for details.
What is the TDN Signature?
A TDN Signature is a long string of numbers containing a timestamp, a unique, impossible to guess number and the Dollar value associated with the TDN. TDN and TDN Signature may be used interchangeably.
I don't keep a lot of cash in my wallet, why should I keep money on my digital devices?

these cards are minimal.

Is the TDN Signature a cryptographic key?
No. Even though it looks like a cryptographic key
TDNSYS is centralized. Isn’t this a 'systemic single point of failure?'
No.This is one of the arguments make by Bitcoin, blockchain and distributed ledger evangelist against centralized systems. These technologies store and process data on multiple computers on the internet. It has to be understood that we are not talking here about data stored on a mobil device or home computer. These are indeed subject to 'single point of failure'.
In a centralized financial system the data is not stored on only one. These systems are implemented using proven technologies used in the Financial Market Infrastructures (FMIs). Data is managed in state of the art datacenters, not some anonymous computers on the internet.
