Nayax Default Credit on Vending Machines: What Is Checked Before Product Selection?

A vending operator may ask why the payment system needs an amount before the shopper has chosen a drink. In a card-first purchase flow, the final product price is not yet known at the first tap. Nayax calls the amount used for that opening check Default Credit. Its official Default Credit guide explains the concept and distinguishes two ways its connected systems may handle it.

What is Default Credit?

Nayax defines Default Credit as the amount a machine pre-authorizes on a customer's payment method before product selection. The purpose is to confirm available funds before vending. In the documented card-first sequence, the customer taps a card or phone, the system checks the configured amount, and the customer then chooses the product. Payment is processed for the actual purchase amount.

This opening amount is not the menu price of every product. It also does not describe a prepaid balance loaded for staff purchases. When reviewing a proposal, ask the payment provider to identify the opening amount and the final sale separately, using the exact flow offered for your installation.

Does it reserve money in the customer's bank account?

The Nayax guide distinguishes Virtual Credit from a Bank Hold. It describes Virtual Credit as a digital authorization without reserving money in the customer's account. It describes a Bank Hold as temporarily reserving the Default Credit amount, with release after completion. The guide associates the latter with older third-party hardware integrations.

Do not turn that distinction into a promise about an unidentified machine. Confirm which method the supplied combination of reader, controller and payment service uses. Customer-support wording should explain the installed arrangement, rather than assuming that every opening check appears the same way in a banking app. The source does not establish a universal bank release deadline for your customers.

What amount should the opening check cover?

Nayax recommends covering the most expensive possible purchase on the machine. For a one-drink purchase, review the highest-priced available drink in the actual menu. If several items can belong to one session, the relevant purchase value may be the combined basket rather than the single most expensive item. Agree that boundary with the provider before setting a value.

A basket that can grow beyond an opening amount creates another question: how is the additional amount authorized? Our incremental authorization buying guide discusses that separate requirement. Multiple-item shopping does not itself establish that incremental authorization is enabled.

What should the buyer see before handover?

Request a provider-approved demonstration of the proposed purchase flow. Record the agreed opening amount, the selected product or basket, and the final payment result. Ask the responsible team to explain the customer message and the support route if authorization is declined or an account entry is unclear. These are suggested acceptance checks, not reports of tests already carried out.

Keep the actual configuration and customer-facing explanation with the handover materials. A generic statement that a machine accepts cards leaves the opening amount unanswered. It also does not establish fees, release times or compatibility with a specific merchant account.

Review the equipment range alongside the payment proposal. This provider-documentation review does not establish that every WEIMI model includes Nayax or a particular authorization method.
