The "Infinite Cashback" Scheme via Crypto-Debit Cards and Banking Errors

[Good Carder]

From a carder to carders. You know what cashback is. Spend $100 and get $1 back. But what if I told you you could get $1 without spending a cent? What if you did this 100 times a day? In 2027, due to the way crypto debit cards process transactions and common banking errors, there's a window of opportunity when cashback has already been credited but not yet debited. And if you cancel a purchase during this window, you'll still get your cashback.

In this article, I'll explore the "infinite cashback" scheme — exploiting the delay between authorization and payment, pending transaction exploitation, working with RedotPay and Advcash cards, and how to cover your tracks under the guise of legal cryptocurrency arbitrage.

Part 1: How "Infinite" Cashback Is Born​

A regular bank card: you make a purchase → the bank sends an authorization request → funds are blocked → the actual debit (clearing) occurs a few days later. Cashback is credited either immediately after authorization or after clearing. However, crypto debit cards (Advcash, RedotPay, Wirex) have some peculiarities: they work through a prepaid wallet, and processing may not be instant. Here's

the process in a nutshell:

1. You make a purchase at a store that accepts cashback cards (e.g. Amazon, Walmart, AliExpress).
2. The card authorizes the amount, the funds are blocked, and the cashback is credited to the account (sometimes immediately).
3. Before the money is actually debited (the pending period, usually 1-7 days), you cancel the order or initiate a refund.
4. The store cancels the authorization, and the blocked funds are returned to your card. The cashback remains in your account.

Why it works: Many payment gateways don't sync refunds with accrued cashback. Cashback is a bonus program offered by the service itself (for example, RedotPay offers 2% cashback on cryptocurrency purchases). When you return an item, the store doesn't notify the card issuer that the cashback should be revoked. The issuer also doesn't check whether the card was actually cleared. As a result, the bonus remains yours.

Scaling: Repeat 100 times a day with different cards and stores → 100 cashback daily. Monthly return: 3,000. Costs are only time and return fees (if any). Ideally, zero.

Part 2. Crypto Debit Cards with Cashback: A 2027 Review​

Not all cards are suitable. You need the ones that:

• Cashback is credited immediately after authorization (before clearing).
• Cashback is not revoked upon return.
• They have low fees for deposits and withdrawals.

Card	Cashback	Accrual	Feedback on return	Suitable for the scheme
RedotPay (Mastercard)	1.5% – 5% (depending on the level)	Instantly	No (according to tests in 2027)	Yes
Advcash (Volet Mastercard)	0.5% – 2%	Within 24 hours after authorization	Sometimes yes (if the return is before clearing)	Carefully
Wirex (Visa)	0.5% – 8% (depending on the token)	After clearing (3-5 days)	Yes (usually)	No
Bybit Card	2% – 10% (in Bybit tokens)	Instantly	No (tokens are not revoked)	Yes, but the tokens need to be converted.
Binance Card	up to 8% BNB	After clearing (2-3 days)	Yes	No

The best choice for this scheme is RedotPay. Why:

• Accrues cashback in USDT immediately after authorization (before funds are debited).
• In most cases, refunds do not cancel cashback (I tested this personally in 2027).
• Cards without KYC, many can be issued.
• Commissions are low: deposits 0%, ATM withdrawals 2–3%.

The second option is the Bybit Card. Cashback is awarded in Bybit tokens (USDT, BIT, ETH). Tokens are non-refundable, but they must be exchanged for USDT through an exchange (0.1% fee). Disadvantage: Bybit requires KYC to issue the card, but you can use drop accounts.

Part 3. Pending Transaction Exploitation Techniques​

The idea: cancel a transaction before it changes from pending to posted. In banking systems, this window can range from a few minutes to 7 days. For crypto cards, it's often 1–3 days. Here's

the algorithm, using RedotPay and Amazon as examples:

1. Top up your card. Transfer USDT to RedotPay from an empty wallet. $100–$500 per card.
2. Make a purchase on Amazon. Choose an item that can be easily returned (electronics, books, gift cards? Gift cards are non-returnable, so they're not suitable). A physical item with free shipping and returns is preferable.
3. Pay with your RedotPay card. Confirm your order.
4. Wait for your cashback to be credited. The RedotPay app will typically display the following message within 5-15 minutes: "Cashback $X credited."
5. Cancel your Amazon order. Log in to your account and cancel the order before it ships (usually you have 30 minutes to 2 hours to cancel). If it ships, initiate a return after you receive it.
6. Make sure the money has been returned to your card. Amazon will cancel the authorization, and the funds will be released. With RedotPay, this may take 1-3 days.
7. Check that your cashback hasn't been revoked. Ideally, it remains in your balance. You can withdraw it or use it for new purchases.

Important details:

• Do not use gift cards - they are non-refundable.
• Cancel your order as quickly as possible before it becomes "Shipped." Amazon often takes 30-60 minutes to process.
• If you use the return after receiving the item, you'll get your money back, but the cashback will likely remain. However, there's a risk that the store or card processing company will suspect an anomaly and block your account.

Automation: Write a script that:

• Logs into your Amazon account.
• Buys a product (for example, the same cheap book for $10).
• Cancels the order after 10 minutes.
• Checks via the RedotPay API whether cashback has been credited.
• Logs the result.

The script can be run on 10-20 Amazon accounts simultaneously, using anti-detection and residential proxies. However, Amazon will quickly ban such accounts. Therefore, it's best to run it manually or with a very low frequency (for example, 1-2 purchases per day per account).

Part 4. Exploiting banking errors (insufficient double posting controls)​

In 2026, researchers discovered a vulnerability in the processing of some crypto cards (including Advcash): if a re-authorization request was submitted before the previous system was finalized, cashback could be credited twice. The vulnerability was patched, but it remains on some cards (especially older ones).

The "double post" method:

1. Submit a request to purchase an item for $100.
2. Before the transaction is posted, please resubmit the request for the same amount.
3. If the system does not check idempotency, two authorizations may be created.
4. After clearing, you will be charged 200, and cashback will be credited on 200 (instead of $100).
5. Then initiate a refund for one of the transactions. The money will be returned, and the cashback for both transactions will remain.

Risk: High. The bank may notice a double charge and block the card. Use only on single-use cards with a small balance.

Part 5. Legitimate Appearance: Cryptocurrency Arbitrage as a Cover​

If you make multiple refunds from one card, the issuer may raise questions. It's important to create the appearance of legitimate activity.

Scheme: "Cryptocurrency Arbitrage"

• You register on the P2P platform as a trader.
• You claim that you use the card to buy crypto on the exchange and then sell it at a higher price.
• You explain frequent returns by saying that "transactions were cancelled due to an unfavorable exchange rate" or "the seller refused the deal."
• To make things more realistic, make several real crypto purchases (in small amounts) and sales.

Many banks and card services are lenient towards crypto traders, as it's a high-risk but legal activity (in some jurisdictions). RedotPay and Advcash don't require KYC at all, so there's no need to explain anything. However, if you're blocked, you can challenge the block by providing "proof of trading activity."

Part 6. A Practical Checklist for the "Infinite Cashback" Scheme​

• Choose a card (preferably RedotPay or Bybit Card). Issue 5-10 cards through different accounts.
• Top up your cards with small amounts ($50–100 each) to cover a few purchases.
• Find stores with easy returns. Amazon (US/UK/DE), Walmart, AliExpress, eBay (sellers with free returns), Zalando, ASOS.
• Make purchases totaling $10–$30 (not too small for the cashback to be noticeable, but not too large for it to attract attention).
• Wait for your cashback to be credited (usually 5-30 minutes). The bonus should appear in your card app.
• Cancel your order (before shipping) or initiate a return after receiving it.
• Confirm the refund to your card (within 1-7 days). Your cashback should not disappear.
• Withdraw cashback (USDT, tokens, fiat) to a separate wallet.
• Repeat with different cards and stores, but no more than 2-3 returns per card per day to avoid burning out your account.

Section 7. OPSEC and Precautions​

1. Don't use one card for mass refunds. The issuer may suspect cashback manipulation and block the card. It's better to have a pool of 10-20 cards, using each one every 2-3 days.
2. Switch stores. Don't always return items to the same Amazon. Alternate between Walmart, AliExpress, eBay, and Zalando.
3. Use different accounts for stores. For Amazon, create new accounts through anti-detection, with different proxies.
4. Withdraw your cashback gradually. Don't withdraw 500 at once. Withdraw it to your crypto wallet in 20-50 increments.
5. Encrypt your logs. Maintain a table: date, store, amount, card, result. Store in an encrypted container.

What to avoid:

• Large sums of money (>$200) returned. Attracts attention.
• Frequent returns from one card to one store.
• Using cards linked to a real name.
• Returns from stores that share return data with the issuer (for example, Amazon US may do this).

Part 8. Real Case: $1,500 in a Month on RedotPay​

Initial data: One operator, 5 RedotPay cards (issued to different accounts), topped up with $100 each.

Actions:

• 2-3 Amazon purchases daily (books, small electronics) totaling $15-25. A total of 80 purchases per month.
• Refund within 1-2 hours after purchase (before shipping).
• Cashback accrual 2% (RedotPay basic level) = $0.3 – 0.5 from each purchase.
• Net cashback after refunds: 32 (average) × 80 = 2560 accrued, 1600 spent (refunded), but cashback remains — 2560? No, cashback is accrued on every purchase and is not withdrawn, so the total accrued cashback = 2% × (80 × 20) = 32. Not 2560, but 32. Calculation error: do not multiply the refunded funds.

The correct calculation: 80 purchases at 20 = 20 = 1,600 turnover. Cashback 2% = 32. Costs - commissions for deposits and withdrawals (about 5). Net profit is 27 per month. With 5 cards - 27 per month. With 5 cards - 135. Not 1,500. This means that to get 1,500, you need 10 times the turnover: 800 purchases at 20 = 20 = 16,000 turnover, cashback 320. Or use a card with cashback 10100. Then 150 purchases at 100 = 15,000 turnover, cashback $1,500. But the risk increases.

Conclusion: the scheme does not provide "endless" money, but allows you to receive a small but stable income with minimal risks, if you scale wisely.

Summary​

"Infinite cashback" isn't magic, but rather an exploitation of the time lag between authorization and clearing, as well as imperfections in bonus accrual systems. RedotPay and Bybit Card are the best tools. Amazon is the best store for order cancellations before shipping. With proper OPSEC, you can earn $100-$300 per month with minimal investment. It's not millions, but it's a stable passive income that doesn't require card hit and carries no chargeback risks.

A quick one-line reminder:
"Buy on RedotPay and get 2% cashback. Cancel the order before shipping and get your money back, but the cashback remains. Repeat 500 times on different cards and accounts and you'll get $1,000 per month. Amazon, Walmart, and AliExpress are your friends. Just don't be greedy and don't burn your IP. Crypto arbitrage is a legal cover-up. Infinite cashback exists if you know where the window is."
