I just “paid” online with a debit card with no funds. What now?
There are a few factors at play here. Depending on the bank that has offered you the card there are different types of overdraft protection that may have been set up. Typically, if they attempt to run the card with no money, if one of these is in play, you will be spared any overdraft fees by the transaction charging to a designated overdraft account, usually savings, or by the transaction failing due to insufficient funds.  If you know the transaction went through, and you know there were not enough funds in the account to cover the transactions, then you have a few options. If you have overdraft protection that auto charges insufficient funds charges to a separate account, then you have nothing to worry about. If you do not, most banks offer a grace period where you have until the end of the day to zero out your account, that is to say pay the overdraft amount and bring your balance to at least $0.  If this is a charge that occurred in the past, and you have already been charged an overdraft fee, there may still be hope. I cannot speak for all banks, but I know that Chase Bank offers a once per year overdraft forgiveness, where they will get rid of the charges if you agree to bring the account out of the negative. There is a chance other banks will do the same if you call their customer service.
Of course its possible. Under what terms and with what fees depends on your bank/country regulations, but generally speaking - loaning is the major source of income for banks, especially short-term account overdrafts (which is essentially a loan, usually at a high rate). In the US you can (now, since the new regulations kicked in) instruct the bank not to pay checks/decline debit card purchases if you don't have sufficient funds on the account. Otherwise you can instruct them to pay (at their discretion) to avoid bouncing checks, and accept NSF fees (usually pretty high). Some banks provide overdraft lines of credit (then you won't have NSF fees, and will just pay interest when tapping into that line), others provide option to automatically withdraw the missing amount from a linked account (checking or credit card). "My wife and I have Gap, Kohl's and Amazon cards. They each give extra benefits when using them at their stores, and usually 1% cash back at other places, although we don't use the Gap or Kohl's anywhere else.  We don't carry a balance, so as mentioned, the rate doesn't matter. And they are so spread out when we've gotten them (Kohl's for a good 3 years, Amazon about 2 months ago) that I don't expect any issues for credit checks. In fact I just got approved for a mortgage loan, way more than what I know I can really afford.  In my mind, credit cards are a bad idea when you use them as ""real"" credit. If they are used more like a debit card (spending money that you have), its like a loan (you don't have to pay it off til later), and you get paid for it (whether in cash or merchandise)." "You might convert all your money in local currency but you need take care of following tips while studying abroad.Here are some money tips that can be useful during a trip abroad. Know about fees :- When you use a debit card or credit card in a foreign country, there are generally two types of transaction fees that may apply: Understand exchange rates :- The exchange rate lets you know the amount of nearby money you can get for each U.S. dollar, missing any expenses. There are ""sell"" rates for individuals who are trading U.S. dollars for foreign currency, and, the other way around, ""purchase"" rates. It's a smart thought to recognize what the neighborhood money is worth in dollars so you can comprehend the estimation of your buys abroad.  Sites like X-Rates offer a currency converter that gives the current exchange rate, so you can make speedy comparisons. You can utilize it to get a feel for how much certain amount (say $1, $10, $25, $50, $100) are worth in local currency. Remember that rates fluctuate, so you will be unable to suspect precisely the amount of a buy made in a foreign currency will cost you in U.S. dollars. To get cash, check for buddy banks abroad:- If you already have an account with a large bank or credit union in the U.S., you may have an advantage.  Being a client of a big financial institution with a large ATM system may make it easier to find a subsidiary cash machine and stay away from an out-of-system charge.  Bank of America, for example, is a part of the Global ATM Alliance, which lets clients of taking an interest banks use their debit cards to withdraw money at any Alliance ATM without paying the machine's operator an access fee, in spite of the fact that you may at present be charged for converting dollars into local currency used for purchases.  Citibank is another well known bank for travelers because it has 45,000 ATMs in more than 30 countries, including popular study-abroad destinations such as the U.K., Italy and Spain. ATMs in a foreign country may allow withdrawals just from a financial records, and not from savings so make sure to keep an adequate checking balance. Also, ATM withdrawal limits will apply just as they do in the U.S., but the amount may vary based on the local currency and exchange rates. Weigh the benefits of other banks :- For general needs, online banks and even foreign banks can also be good options.  With online banks, you don’t have to visit physical branches, and these institutions typically have lower fees. Use our checking account tool to find one that’s a good fit. Foreign banks:- Many American debit cards may not work in Europe, Asia and Latin America, especially those that don’t have an EMV chip that help prevent fraud. Or some cards may work at one ATM, but not another. One option for students who expect a more extended stay in a foreign country is to open a new account at a local bank. This will let you have better access to ATMs, and to make purchases more easily and without as many fees. See our chart below for the names of the largest banks in several countries. Guard against fraud and identity theft:- One of the most important things you can do as you plan your trip is to let your bank know that you’ll be abroad. Include exact countries and dates, when possible, to avoid having your card flagged for fraud. Unfortunately, incidents may still arise despite providing ample warning to your bank. Bring a backup credit card or debit card so you can still access some sort of money in case one is canceled. Passports are also critical — not just for traveling from place to place, but also as identification to open a bank account and for everyday purposes. You’ll want to make two photocopies and give one to a friend or family member to keep at home and put the other in a separate, secure location, just in case your actual passport is lost or stolen." Get a credit card is NOT the answer. The reason people have a bad (or no) credit score is often because they're new to the country, have just turned 18, have previously fallen into arrears or are just bad with money. Getting a credit card is risky because, if you don't stay on top of your payments, it'll just damage your score even more.  Now, it sounds like I hate credit cards - but I don't, and they do have their benefits. But avoid them if possible because they can be more hassle than they're worth (ie, paying the credit back on-time, cancelling accounts when the interest comes in, moving money in and out of accounts). It's risky borrowing money from anywhere whether it's a payday lender, a bank, a credit card, etc., so use them as a last resort. If you've got your own income then that's amazing!, try not to live outside of your means and your credit score will look after (and increase) itself. It takes time to build a good credit score, but always make sure you pay the people you owe on time and the full amount. I'd stick with paying your phone provider (and any other direct debits you have setup) and avoid getting a credit card. I'd recommend Noddle to keep track of your credit score and read their FAQ on how to help build it. Unlike Experian, it's free forever so not quite as detailed... but Noddle are owned by CallCredit - one of the biggest Credit Reference Agencies in the UK so they should have the latest information on yourself. In conclusion, if you already have financial commitments like a mobile phone bill, gym membership, store cards, anything that gets paid monthly by direct debit... your credit score will increase (provided you pay the full-amount on time).   I hope this helps. PS. I don't work for any of the companies here, but I've been working in the finance sector (more specifically, short-term loans) for 3+ years now. I've had fairly extensive experience using Entropay, with a few hiccups along the way. I suspect your transaction or repeated top-ups has been flagged as 'suspicious' activity. Read: potentially fraudulent or money laundering.  You've also tried to buy expensive electronic goods, a common use of fraud/laundering. Finally, Entropay does NOT provide address validation. Again, with laptops being a common use for fraud, it is more than likely Lenovo attempted to do an address validation on your card details, which failed and may have led to the hold. How to resolve it? You will probably need to provide documentation to Entropay including proof of identity and where you live. I had a similar situation a while ago, and here's what I learned: What are our options here to ensure that this company can't retry to take our money again via ACH? Close existing account and create a new one that has different account number? Yes. As a temporary solution keep ~$0 balance in the account so that their request for $840 can't be fulfilled? However, would our bank incur any fees because of insufficient funds each time the other company tries to charge us again? Bad idea. You may incur penalties for returned payment, or the bank may honor the payment and charge you overdraft fees. Provide to our bank the service termination notice that proves that we   are not in business with the other company anymore and effectively   block them. However, termination notice has only our signature Bank doesn't care. ACH withdrawal is akin to a check. The assumption is that the other side has entitlement. You can put stop payment once its processed and try to reverse it claiming fraud, but the end result will be #1: you'll end up getting a new account set up, while they try to recover the money. This is one of the reasons I'm reluctant allowing standing ACH authorizations any more. Generally, the American banking system is very much geared against the consumers, and in many ways is very retarded. In a more advanced countries (which is almost any other country than the US), the standing withdrawal authorization goes through your bank and can be revoked. Things are generally fine.  A credit balance is not a horrible thing.   The argument against maintaining a credit balance is that you are essentially loaning the credit card issuer money at 0% interest.  You probably have alternative investments that would pay better interest, so it's usually better to park your money there.  All that said, it's unlikely that the interest on whatever balance you have is enough to be more than pennies.   The way that a credit card works, you run up a balance in one period.  Then there is a grace period.  If you don't pay off the balance during the grace period, they start charging you interest.  You also may have a minimum payment to make.  If you don't make that payment, they'll charge you a late fee.   The typical period to rack up charges is from the first to the last day of a month.  The typical grace period is through the 20th or 25th of the next month.  Your card may be different.  So check the documentation (user agreement) for your card if you want the real data.   It sounds like you paid off some purchases while you were still in the period where you rack up charges.  While those purchases were posted to the account, they may not be counted in the balance calculation.  If your credit balance exactly matches the payment you made, that's probably what happened.  It's also possible that you overpaid the balance.  If your credit balance is just a small amount, that's probably what happened.   If you really want to be sure, you should call the credit card issuer and ask them.  At best we can tell you how it normally works.  Since this is your first month, you could just wait for your first bill and respond to that.  So long as you pay off the entire balance shown there by the deadline, everything should be fine.   Don't wait until the last day to pay.  It's usually best to pay a week or so early so as to leave time for the mail to deliver the check and for them to process it.  You can wait longer for an online payment, but a few business days early to give you a chance to handle potential problems is still good. It is possible that the person you were on the phone with was in possession of the credentials of a paypal account that was not actually theirs.  The sad truth is that there are a lot of scammers out there and they can be very convincing while talking to you on their burner phone.     Then they send you money and before the actual owner of the account can do anything the scammer gets you to surrender your goods.  Then the payment gets reversed and when you call that phone number they used no one answers, or the phone is not in service. For this reason do not release the product until you actually have the money.  For software work use an escrow account at a reputable bank to ensure that the funds will be available when you complete the work.
