There are countless methods of manufacturing credit card spend, but the basic principles are simple: generate a credit card purchase (usually at some cost), liquidate the purchase back to cash (usually at some cost), and use the cash (plus any costs paid) to pay off the credit card balance. If you generate more in credit card rewards than you pay in costs, the technique is profitable.
In some cases these techniques are still profitable to the banks and merchants, and in others they’re unprofitable but travel hackers are too small a share of customers to be worth completely rooting out, so only half-hearted and incomplete efforts are made to remove the very hardest hitters.
A central feature of credit card manufactured spend is that it relies on spending as much as possible: more spend equals more profit. Debit card manufactured spend is often just the opposite: the goal is to generate transactions, not spend, and this creates surprising difficulties.
Why manufacture transactions?
There are a few main reasons you might want to manufacture debit card transactions. Some accounts charge fees for inactivity, and a $0.01 debit card transaction is enough to avoid the fee.
Other accounts, like the Consumers Credit Union Rewards Checking account that I use as my petty cash account, require a certain number of debit transactions to trigger their higher interest rates. Note that there are other, higher-interest-rate options available; I find DepositAccounts.com quite reliable for tracking them.
A product that, as far as I know, never took off in the travel hacking or personal finance community is the round-up savings account. These accounts have high interest rates but can only be funded by “rounding up” your change on debit card purchases. To achieve a meaningful balance in the account, it’s necessary to make an arbitrary number of debit card transactions with a cent value as close to 1 as possible, resulting in a 99-cent deposit.
Why is manufacturing transactions so hard?
I found it a bit counter-intuitive at first that manufacturing transactions profitably is as complicated in its own way as manufacturing spend. In both cases, the issues come from the fact that we’re using tools we don’t control for purposes they aren’t designed for. Here are some of the main problems I’ve encountered.
-
Per-transaction costs. While many financial services have lower fees for using debit cards than credit cards, that’s primarily by charging flat fees rather than lower percentage fees, and flat fees make manufacturing transactions more expensive.
-
Transaction minimums. A lot of options require transactions of at least $1. This is an obstacle to scaling, since even if you’re recuperating 100% of your transaction value, the larger each transaction must be, the more money you need to have tied up in the system at any one time.
-
Processing rules. If a service processes your transaction as “PINless debit,” instead of as a credit card, then it may not count towards monthly transaction requirements. For round-up transactions, there may be rules about how far apart transactions have to be spaced.
-
Closed loops. A lot of obvious options do work, but the money goes into a closed ecosystem where it has to be spent. Your Amazon gift balance can only be spent at Amazon, payments to your electric company have to be spent on electricity, etc.
-
Automation. Arbitrage opportunities are so persistent not because they’re particularly complicated. Most of them could be learned by a person of average intelligence over the course of a light lunch. The reason they last so long is that most people already have a job and don’t want another one. Automation is a solution, but researching ways to safely automate large numbers of financial transactions is yet another job.
These constraints can interact with each other as well. Your cable provider might allow you to automate payments with a minimum of $1, which looks like a tidy solution until you realize that your cable bill can only be spend on cable, which puts a soft ceiling on the number of transactions you can generate with that method each month.
Here’s a roundup of the options I’ve looked into and some thoughts on each.
Plastiq (grandfathered)
I’ve used the Plastiq bill payment service on and off for years now. It’s changed so much that instead of using it overwhelmingly to manufacture spend, I now use it primarily to manufacture transactions. Under their old pricing model, using debit cards had a low fixed fee, so I scheduled twelve $1 payments per month until sometime in mid-2026. If I fall into a coma, at least my money will still be earning 3% APY.
As far as I can tell it’s no longer possible to get access to the old pricing, but this highlights the kinds of feature you want to look for as these services continue to pop up: low per-transaction price (I pay $0.01 per transaction, so $0.12 per month), easy liquidation (the $1 “payment” gets deposited into another account a week or so later), and long-term automation.
Peer-to-peer payments
I’ve had great success manufacturing round-up savings transactions with Venmo. They have a $0.01 minimum transaction and no fees for debit cards. The $0.01 has to go somewhere, and I’m not comfortable running multiple accounts and risking losing access to the tool entirely, so I send it to another person. This does generate a lot of annoying e-mails, so you probably want to set up some filters so those e-mails don’t drove you or your teammate crazy.
Cash App works as well, but has a $1 minimum transaction, which makes it a cumbersome way to generate round-up transactions. It works well for manually generating monthly transactions, so I do use it to meet the 15-monthly-transactions requirement on my Andrews FCU Kasasa Cash Checking account to earn 6% APY on up to $25,000.
Neither option has built-in automation. There used to be a way to interact with the Cash App ecosystem by text message, which would be a convenient way to automate transactions, but I couldn’t easily find any current documentation of that feature so my guess is they retired it at some point.
Store credit
I reload my Amazon gift card balance $1 at a time to meet some of my monthly transaction requirements, and I was pleased to discover that my $7 monthly Prime membership is charged first against my gift card balance, so I don’t need to worry about storing up too much unused Amazon credit.
I say store credit instead of Amazon credit because a lot of people have several services that have this feature. If you can load your transit pass, Starbucks balance, or cell phone balance $1 or $0.01 at a time then you can meet transaction requirements without the risk of locking up money you’ll never end up spending.
Conclusion
I understand that people feel themselves at a constant shortage of time and attention, even for the things that give them great joy and satisfaction. They are not only uninterested, but often almost offended by the suggestion they’d waste those precious resources on the essentially meaningless task of pushing buttons on their phone for a few minutes a day.
Believe it or not, I don’t find it especially fun or meaningful to push buttons on my phone for a few minutes a day either. But that’s a pretty high bar to hold every minute of your day too. I don’t find it especially fun or meaningful to brush my teeth either, but I’d like to still be chewing with a few originals by the time I’m 80 so I do it anyway.
Whether it’s earning the highest interest rate possible on my liquid cash in high-yield checking accounts, or dumping as much money as possible into my best savings accounts, I just don’t mentally categorize it as something that’s supposed to be fun. You fill out your timesheet in order to get paid, not because it’s going to bring about world peace.
