    Well yeah, they're always recording everything you say, the wake word is just for show.

    You still use the "wake word" to initiate the conversation. You just don't have to say it again at the beginning of each sentence during an ongoing conversation.

    These home assistants use regular Wifi, and you can monitor the packets they transmit and receive. There is no evidence that they are "recording everything you say". If they were caught doing that (and they would almost certainly get caught), they would face ruinous criminal charges and civil penalties, along with a PR disaster that would far outweigh any possible benefit.

    I think there should be a "ummm, so I'm told" in there somewhere.

    On Nanjing Lu the working girls can be pretty aggressive. If you are an obvious tourist, they will walk right up to you and ask if you want a "massage" in your hotel room. I usually reply "Wo mei you qian" (I have no money), to which they reply "You can pay with WeChat".

    What does it show up on your statement as?

    It would list her name, just like in any other peer-to-peer transaction.

    Unlike in English, most Chinese names are not gender specific. Chinese pronouns also have no gender when spoken (but do when written), so it is common to have a long conversation about a third person and still have no idea if you are discussing a man or a woman. That is almost impossible in English.

    Surcharges have decreased

    In China, they have gone to zero. There are no cashless transaction fees as far as I can see. The amount received is alway exactly the same as the amount sent.

    I guess they make money on the data, and on the float. If a billion users each have $1000 CNY ($150 USD) in their account, that is a trillion CNY ($150B USD) of float. The data must also be worth a lot. Google makes billion and billions, and knowing my search terms is a lot less useful than knowing what/when/where I buy. So the data collected by Tencent and Alibaba must be worth even more.

    How does the phone/bank/whoever know the amount I want to pay?

    At many shops, the price is embedded in a QR-code that appears on a LCD screen. You just scan it and tap to confirm. At low end shops, such as street stalls without electricity, there is a fixed QR-code sticker and the vendor just tells you the price. You key it in and tap your fingerprint to authorize.

    I guess the shop needs a networked computer of some sorts after all, right?

    No. In theory, the merchant can just look at your phone to see that the transaction completed. In practice, they will usually also have their cell phone which will display the completed transaction. Everything is cell phone based, and there is no wired network, nor even a need for electricity other than your cell battery.

    Cash if FAR cheaper. Having to accept credit cards entails a hefty surcharge by the credit card company

    I was in China for two months last fall, witnessed thousands of cashless transactions, and this is how many times I saw anyone use a credit card: 0.

    Cashless payments ARE NOT BASED ON CREDIT CARDS.

    as well as a delay in getting paid,

    WeChat and AliPay are instant transfers.

    ... and the additional risk of credit card fraud.

    Credit card fraud is an AMERICAN problem. In other countries I can't spend your money just by providing semi-public information. Only Americans believe that is "the way it is supposed to be".

    While a debit card is faster and cheaper it still involves network fees and equipment rental and service.

    Equipment needed to accept cashless payments in China: A sticker with a QR-code. Cost: 2 cents.

    That all sounds like it takes more than two second.

    It only takes more than 2 secs if you don't already have the WeChat app open. But that is rare in China. WeChat is like SMS, voice mail, Facebook, Twitter, Instagram, Skype, Facetime, PayPal, plus a lot more, all rolled into one app. If you see a pedestrian in America, there is maybe a 50% chance that they aren't watching where they are going because their eyes and attention are on their phone. In China, it is at least 90%.

    Even if you don't already have WeChat open, you can open it while you wait in the checkout line, so by the time you get to front, all you have to do is scan and tap.

    Do they not take cash in China?

    Most merchants still take cash, but more and more do not. As cash users dwindle, it just isn't worth the hassle and risk for businesses to keep cash on hand. Any merchant can accept e-payments, even informal unregistered businesses. A farmer was selling apples out of a wagon on the street in front of my apartment ... with a WeChat QR-code sticker on his scale. Just weigh, scan, and go.

    I can just wave my phone? Do I have to flip it open, or can I leave it shut?

    I have no idea how it works in Sweden, but in China you use an app to scan the merchants QR-code, and then enter a 6 digit PIN and/or use finger/face ID to confirm the transaction. It typically takes about two seconds. I set up my phone to use fingerprint only for transactions under 100CNY ($15 USD) and require both PIN and fingerprint for larger amounts.

    And how do I pay to refill the phone with the phone?

    You can top-up your balance by linking your WeChat or AliPay app to your bank account. This requires an additional bank PIN. Or, if you don't have a Chinese bank account, you can ask a friend to send you a "hong bao" peer-to-peer transfer.

    Of course the Chinese are going to have a system in place to track everything you do.

    They already have that and there is no secret about it. I was just there to get my job done, so I go along with the system, obey the law, and keep out of trouble. They certainly aren't going to change their policies because I object. As an American, it is not my job to "fix" China.

    Even from a business owner's perspective, there's nothing that says your business has to accept cash payments

    But if few businesses accept cash, and you can't actually use cash to buy groceries, then you have a de facto cashless society.

    For businesses, cash means crime. Both employee theft and robberies. Cash transactions are also slower than just waving your phone, which raises costs. Cashless self-checkout kiosks are cheaper and less error prone than those that handle cash.

    I spent two months working in Shanghai last fall. I ate hundreds of meals, visited dozens of shops, and exchanged money with co-workers. Of all those transactions, this many involved cash: 0.

    How many pristine, never used card numbers are actually left and when we will start reusing old numbers?

    CC#s are 16 digits, so there are 10 quadrillion combinations. That is roughly 1.4 million numbers per person.

    Only one of 10 of those numbers has a valid checksum, and there are some other restrictions (Visa always starts with "4", MC with "5", etc.), but there is no way we are ever going to run out of numbers.

  22. Then we move into other information often lost due to this kind of negligence that need replacement mechanisms also - SSN, DL#...

    There is no need to replace SSNs and DL#s. We just need to ban their use in authentication. Knowing an SSN should not be used to authenticate identity. It should just be an index number.

    When my bank needs to authenticate my identity, they text a code to the cellphone linked to the account. That is not perfect, but it is WAY more secure than asking me for the last four digits of my SSN.

    No CC number need be exposed.

    They need the CC# to do the refund. The customer might not have it with them, or might not remember which card they used. So the clerk needs to be able to retrieve the number.

    Of course this is stupid, and other countries do it differently. For instance, in China, the transaction ID itself can be used for the refund, without any need for the CC#. In fact, the CC# is not even needed for the original purchase. You just need the cell phone linked to the account, along with a 6 digit PIN, and either your face or your fingerprint. CC fraud in China is nearly non-existent.

    If that were actually true, America would have by far the world's lowest crime rates. It doesn't. In the developed world, it has one of the highest crime rates. You should read up on "evidence based reasoning".

    the situation continues just the same as it has occured for years.

    Then it should be obvious that we need to FIX THE PROBLEMS rather than just pounding harder on the defects.

    Our current CC system is DESIGNED to be insecure, because Visa and MasterCard have no incentive to fix it, and actually benefit from additional fees for chargebacks. Blaming the merchants (who bear much of the cost of fraud) and/or end users (who also bear part of the cost) is silly.

    ... back to work waiting until the next breach.

    You are completely missing the point. With a proper 2FA or 3FA system, disclosure of CC#s DOES NOT MATTER, because there would no longer be any reason to pretend they are "secret". In fact, the CC#s themselves would matter so little, that we could just print them directly on the cards.

If we are going to start imprisoning people for incompetence, we will need to vastly expand our already bloated prison system and raise taxes to pay for that.

    I understand that it feels good to say "lock em up" every time we have a social problem, but if you think that is actually "the" solution, then you need to grow up.

    Here is the solution: Get rid of the idiotic CC system that relies on the same information being both widely known and secret. There is no way that mere knowledge of a CC# and exp-date should be enough to use it to buy stuff. The CVV helps a little, but not much since it is printed on the card. .
