A declined payment usually has one of four causes, and most can be checked in a minute. Here is the order to check them in, with the fix for each.

Money in the wallet and money on the card are not the same balance. The card spends only the available balance that has been moved onto it, so a payment larger than that amount is declined. There is no credit and no overdraft to cover the difference. In Nexus Pay you move funds from the wallet balance to the card for 0.1%, so the fee is taken from the transfer. For example, 1000 USDT moved to the card becomes $999.00. If you need to pay exactly $1000, move a little more than that.
Yes. A frozen card declines every payment until it is unfrozen, whatever the balance. Freezing and unfreezing is done in the app in one tap, so it is easy to do by accident or forget about. If a payment fails and the balance looks fine, check the card status before anything else. Once the card is unfrozen, try the payment again.
A merchant or terminal that does not accept the card network will not complete the payment even when the balance is fine. Nexus Pay cards run on Visa, so a place that takes only other networks will refuse it. The card type matters too. The virtual card works online and contactless through Apple Pay and Google Pay. The physical card, delivered by mail, is the one for tills and ATMs. If the same card works elsewhere, the problem is likely the terminal, and trying another payment method at that shop is the practical answer.
A payment and a cash withdrawal are separate operations. ATM limits and ATM-operator rules can block cash even when card payments work normally. Cash also carries its own costs: Nexus Pay charges 0.25% per ATM withdrawal, and the ATM owner may add its own fee, shown on the screen before you confirm. In the fee page example, 1000 USDT withdrawn at an ATM leaves $996.50 before any ATM-owner fee. The fee is charged per withdrawal, so one larger withdrawal costs less than several small ones for the same total.
| Cause | How it shows up | What to do |
|---|---|---|
| Card balance too low | Payment above what is on the card is refused | Move more from the wallet to the card (0.1%) |
| Card frozen | Every payment is refused, whatever the amount | Unfreeze the card in the app |
| Network not accepted | Refused at one merchant or terminal, works elsewhere | Use another payment method at that place |
| ATM limit or operator rule | Cash is refused while shop payments work | Check the ATM's limits and rules, or pay by card instead |
Work through the causes in order, from the cheapest check to the least likely:
If all of this checks out, the terminal or merchant is the likely cause, so try another payment method.
Keep some spare room on the card above what you plan to spend, remembering that moving funds costs 0.1%. Check the card status in the app if you freeze it for safety, since a frozen card will refuse every payment. Carry a second way to pay when you visit places where card acceptance is uncertain. For cash, plan one larger withdrawal rather than several small ones, and read the ATM screen for the owner's fee before confirming.
