Best bank card for a copywriter

Hey there! I have been working in copywriting for several years and I found a good option to get payment. That's Blackcatcard. The issue is that i live outside Europe and my clients sometimes have doubts about sending money to my local account. So I opened an european account for free, the card was sent to my address for free as well. I can use the card in any shop and withdraw cash at any ATM with a 2% fee (min 1,5 euro) wherever Mastercard is accepted. For Europeans the conditions are more…

GnuPG – connecting to specific card reader when multiple reader available

Currently I can use

$   gpg --card-status 

to interact with smartcards that run the OpenPGP applet. Through trial-and-error, it seems that only the first card reader will interact with gpg. Using options that pass to scdaemon seem to be deprecated:

$   gpg --reader-port  1 --card-status gpg: WARNING: "--reader-port" is an obsolete option - it has no effect except on scdaemon 

Is there a way to interact with an OpenPGP smartcard that is not connected to the first card reader?

Are web worker / service worker secure environments to store a password, credit card information, access tokens?

If there is a case where I wish to store sensitive data like a password, credit card information, or access tokens:

Are web workers / service workers a secure environment, where such data can not be compromised? If so, what to do to really secure it? If not so, why not exactly?

What can be done with Credit or debit card informations asked by websites?

Many websites ask for payment by entering information from Credit card such as VISA card/ Mastercard etc. Now, till date I knew that I should never tell anybody about these numbers. Then why these websites ask for credit card details and if (suppose) any of them have a malicious intent, then what can they do with these numbers?

Basically my question is, how it is being ensured that they will take the specific amount of money/ cost upon my consent; and without my consent they will not take money? Will the bank send me some verification code to my phone?

I never yet used online transactions and I am very confused to understand its steps, do’s and don’ts etc. I have searched Google and Quora but I didn’t find anything helpful.

I would be thankful if anyone can explain how this specific online transaction mode (by entering credit/debit card number) works and how an without-consent-transaction is prevented, preferably via a flow chart.

Many thanks in advance.

Is using a firewall debit card a good solution to protect my main credit card? [closed]

I’m using Curve, a physical debit card that connects all your credit and debit cards in one and let you decide which one to use at each transaction by using its own app.

I’ve used it with my lower limit credit cards and I really enjoy its features (like instant notifications etc). I recently managed to get a premium credit card from my bank and I wanted to ask you if you think it’s a good idea to link it to this service (or similar ones) in a way to protect my main premium credit card data to be exposed online and in real life. I would store my premium credit card in a safe place and spend with this curve card.

Is this a good idea from a security standpoint?

What could be the reasons for two different OTP messages for the same merchant when we do online transactions through debit card?

While I was doing a transaction (say adding money to one of the mobile wallets) through a SBI debit card, I could see two different OTP messages for different transactions. (Please refer to the image)

Say one time I am adding X amount, So I was getting OTP message from SBI but in the next transaction when I was adding Y amount, I was getting OTP message from BHIM SBI Pay.

What could be the reasons behind it? Is it becuase of the payment gateway (Like PayU,CC Avenue) or somethineg else? Has anyone else observed the OTP message coming in the name of BHIM SBI Pay / SBIPAY? AD-SBIPAY

Is a random number secure (enough) for card numbers and pins?

I’ve been given the task of generating some gift tokens which comprise a serial number and a pin number, analagous to a pre-paid credit card. The serial and pin will be printed on a card, with the pin behind a scratch panel.

My first thought is for both numbers to be randomly generated with the serial number being unique. Is this secure against guessing?

To my simple mind, adding any kind of logic would make the numbers more gussable as there’d then be something to figure out and understand, whereas random is without reason (ignoring implementation details for now), and so while being simple using pure random gives the attacker less to work with.

Is this a flawed assumption? Are there known “good” ways of doing this?

How do the damage rules from blogofholding’s “5e monster manual on a business card” work?


5e monster manual on a business card

Damage: This is the damage budget for all the monster’s attacks. Limited-use (daily, recharge, or situational) attacks do 4x the damage budgeted. Multi-target attacks do ½ the damage budgeted. Limited-use multi-target attacks do 2x. All other damage sources are 1 for 1, including at-will and legendary single-target attacks, auras, reactions, and variable-length effects like Swallow. If a monster has several at-will options (such as melee and ranged), the lower-damage options are free.

The example stat block that the author uses to illustrate these rules involves a low-level creature that can only make a single attack per round, and in this situation the rules seem to work out. I’m having more trouble figuring out how the rules work when you start throwing multiattack into the mix or when you get into the higher levels with powerful creatures that have legendary actions, for instance.

The Monster Manual lists the Adult Red Dragon as a CR 17 creature. According to the blog’s rules, this would give it a damage budget of 85. The dragon’s fire breath is a limited-use, multi-target attack that deals an average of 63 points of damage to those who fail their saves, so as per the rules this should use up 31 out of the 85 budget, leaving 54.

The legendary Wing Attack also falls into this category and so should use up 7 more of the budget, leaving 47.

The blog’s rules indicate that only the most powerful at-will attack, which is a 1 for 1 on the budget cost, requires any budget, which means that the Bite attack eats up the 26 of the remaining budget, leaving 21.

Is this correct? Does the fact that the dragon has multiattack come into play in the budget calculations? Or is it that the dragon is a powerful creature and thus based on “concept” it should be up to 50% higher on the damage budget? In this case, we’re looking at a budget of up to 127, and then it seems like accounting for every attack available works out: 31 for the breath weapon, 7 for the wing attack, 26 for the bite, 15 x 2 for the claws, 17 for the tail, for a total of 111.
