Bitcoin is so 18th Century. We want something 21th Century.

Bitcoin debit cards

[12648430]

You don't seem to have considered the technological issues in play. A debit card is a passive medium, and as such can only operate by giving full access to whoever reads it (and has the PIN); it essentially gives up its private key to whoever reads the stripe. Giving out your private key is so 20th century.

Are fucking kidding me? Debit cards are becoming more and more dated every single day.

We are slowly doing away with any type of card and wallets in general, keeping everything on one device, our phone.

You can already access your house, car, money and more with your phone alone.

It'd be easier to pay with a smartphone

...

something you slide and punch 4 or 5 or 12 numbers in.  yeah.  that' s a PIN

now can we put the two together.  and like have a Bitcoin Debit Card

puleeze!

Yes, I think we'll see this in the future. The payments will probably be off-chain and authorized by an online wallet service (holding limited funds), but it will allow people to spend their coins in a practical manner.

This does exist already.

Coinkite.com is a company that is bringing BTC to Debit Cards.

BTC is still pretty new to physical locations, but once adoption grows bigger, i think we will see more 'physical' types of Payments.  Coinkite is a Canadian company, and we're pretty advanced in payments using NFC for everything these days.  We'll probably see contactless bitcoin payment using NFC on mobile phones shortly.

A store can put a QR code on items in a store as a pricetag, and with the right web backend, you can use your smartphone to buy the stuff right there, not have to wait in line, and leave the store with a digital receipt on your browser screen.

Loss prevention agents can see the item locations in the store where you bought stuff, and visually correlate that with cart contents leaving the store with an overhead camera pointed and zoomed down to cart level. In most cases this will be done in a second with a good eye (or optical recognition of items), and any questions further than that will mean you just have to show your digital receipt on your screen.

By the time you get to the door, doublespend attempts will be detected, so merchants can feel safer accepting BTC as people shop, than having to deal with credit card fraud and paying cashiers to waste time trying to deter/prevent it.

That is a revolutionary step further than self-checkout, where you have to wait in line to use a central computer bank.

The product pages could have buttons for 'add to cart' (generating a single address at the beginning of the session, then revealing it at the end with a bitcoin:1addresshere?amount=grandtotal URL which all mobile wallets should be standardized to open), or 'buy only this item and leave store' (which would fire the URL right away and generate the receipt when the TX is broadcast).
