Bayarcash uses **dynamic** DuitNow QR. Each payment gets its own QR, with the amount already in it, and the QR expires after about 5 minutes. A **static** QR is one fixed QR, often a printed sticker, and the customer types the amount. Bayarcash does not offer a static QR.

## What each one does

Both types use the same DuitNow QR standard, so your customer can scan them with any banking app or e-wallet that supports DuitNow QR. The differences are in how the QR is made and used:

| | Static QR | Dynamic QR (Bayarcash) |
|---|---|---|
| What it is | One QR for all payments | A new QR for each payment |
| Amount | The customer types it | Already in the QR. The customer cannot change it. |
| Where it comes from | Printed once, for example as a sticker at a counter | Made for each order: on the Bayarcash payment page, on your own page through the API, or in BCL QR Terminal |
| Time limit | None | Expires after about 5 minutes |
| Match a payment to an order | You match it by hand, from the amount and the time | Automatic: the QR holds the order |
| Payment confirmation | You check your bank or e-wallet app | Bayarcash sends the result to your shop or system, and the payment shows in **Transactions** |
| Risks | The customer types a wrong amount. Someone sticks a fake QR over yours. | Low. The amount and your shop name are set, and an old QR stops working. |
| Refunds | A refund is a new payment back to the customer. DuitNow has no void. | The same |
| Disputes | The customer contacts their bank or e-wallet, within 60 days | The same |
| Typical use | Market stalls, donation boxes | Online checkout, invoices, payment links, counters with a screen |
| On Bayarcash | Not offered | Yes |

## How your customer pays

Your customer scans the QR with their banking app or e-wallet. The app shows your shop name and the amount. The customer confirms the payment, and the app shows a receipt. For the screens in each app, see [How your customer pays with DuitNow QR](/duitnow-qr-payment-steps/).

If the QR expires before the customer pays, show a new QR. Do not ask the customer to pay to an old QR.

## Take QR payments at a counter

Bayarcash has no printed QR for a counter. Use BCL QR Terminal instead. BCL is a Bayarcash product to sell without a website. QR Terminal turns a phone, tablet or laptop into a payment counter:

1. You type the amount.
2. QR Terminal shows a new DuitNow QR for that sale.
3. The customer scans it and pays.

The payment goes through your Bayarcash account, so it shows in **Transactions** with your other payments. See [QR Terminal in the BCL Help Centre](https://docs.bcl.my/qr-terminal/).

## Fees and payouts

The DuitNow QR fee is the same for each payment, online or at a counter. To see the fee and the amount that you receive, use the [payout calculator](/payout-calculator/). Payouts follow the normal [payout schedule](/payout-schedule/).

## Tips

Two habits prevent most QR problems:

- **Show the QR only when the customer is ready to pay.** The QR expires after about 5 minutes.
- **Check Transactions before you make a new QR for an order that the customer says they paid.** This prevents a double payment.

## Common issues

### Can I print one Bayarcash QR for my shop counter?

No. Bayarcash does not offer a static QR. For sales at a counter, use BCL QR Terminal. It makes a new Bayarcash DuitNow QR for each sale, on a phone, tablet or laptop. See QR Terminal in the BCL Help Centre (https://docs.bcl.my/qr-terminal/).

### My customer says that the QR expired. What do I do?

Each QR is valid for a short time only, about 5 minutes. Start a new payment, or show a new QR for the same order. If the customer says that they already paid, check the payment in Transactions first, so that they do not pay two times.

### Can my customer change the amount after they scan the QR?

No. The amount is in the QR. To charge a different amount, start a new payment.
