Describe workflow in existing payment systems
|
||
|
|
- Cash
|
||
|
|
- authentication at ATM
|
||
|
|
- transaction authenticated by the cash
|
||
|
|
- worries : counterfit bills, wrong currency, etc.
|
||
|
|
- refunds
|
||
|
|
- CC authentication
|
||
|
|
- online vs offline
|
||
|
|
- extended verification
|
||
|
|
- credential theft
|
||
|
|
"this reversal of authentication vs shoping slows shopping"
|
||
|
|
- worse because exposing yourself to a merchant
|
||
|
|
- can choose not to use a particular ATM
|
||
|
|
- 40 million stolen at target
|
||
|
|
- refunds, annoys banks
|
||
|
|
- swipe vs chip vs NFC
|
||
|
|
- Bitcoin
|
||
|
|
- external application
|
||
|
|
- p2p not prowser friendly
|
||
|
|
- 5+ or 10 minute transactions mean designing new shopping carts
|
||
|
|
- minning suck0rs,
|
||
|
|
- massive transaction fees : blockchain.info
|
||
|
|
- hits you 2-3 times
|
||
|
|
- conversion sucks
|
||
|
|
- DDoS : wired article?
|

|
||
|
|
- wallet
|
||
|
|

|

|
Taler payment process from customers prospective
|
||
|
|
- similar to cash
|
||
|
|
- ATM
|
||
|
|
- merchant
|
||
|
|
- contract
|
||
|
|
- digitally signed is better than paper reciept
|
||
|
|
- failure modes
|
||
|
|
- insufficent funds
|
||
|
|
- restoring from backups causes double spending
|
||
|
|
- mint gives proof
|
||
|
|
- restoring from backups can lose coins
|
||
|
|
- mint not accepted by merchant
|
||
|
|
- F
|
||
|
|
- change
|
||
|
|
- refunds
|

|
|
vs CC
|
||
|

Wallet provides isolation
|
||
|
|
Near copy from EXIST protosal?
|
||
|
|
- Limits user risk
|
||
|
|
- Nearly eliminates risk for merchant and mint
|
||
|
|
- lower transaction fees
|
||
|
|
- Reserves simplify things
|
||
|
|
|
||
|
|
Denomination choice
|
||
|
|
- Anonymity refresh protocol
|
||
|
|
- Withdraw automates like ATMs
|
||
|
|
|
||
|
|
Broser extension
|
||
|
|
- RESTful vs Bitcoin, OpenCoin, etc.
|
||
|
|
- Retrying RESTful transactions always works
|
||
|
|
- minimizing dialog
|
||
|
|
- see & pay ??
|
||
|
|
- TBB integration
|
||
|
|
- Needed anyways
|
||
|
|
- Other browser integration?
|
||
|
|
- Is it wise? Ok if not worried about anonymity Taler is still better
|
||
|
|
- Is tor2web worse?
|
||
|
|
- W3C
|
||
|
|
|
||
|
|
Autopay? pat payment recognision?
|
||
|
|
- dangerous?
|
||
|
|
- high charges
|
||
|
|
- good for funny money
|
||
|
|
|
||
|
|
NFC
