Member | A participant of an IPS. The member can be a direct or indirect participant.

An indirect participant is a member not having its own settlement account in the settlement system. An Indirect Participant has a contractual relation with a Direct Participant, to allow its payments being service on the settlement account of the Direct Participant. NB: In the context of this Rulebook, the term “member” is used in a limited sense, specifically to refer to the participation in the local IPS (and may cover one or more local schemes – not only Instant Payments, but also batch payment, direct debit or other). The term “Nexus Scheme Participant” is used in this Rulebook to refer to an entity that participates in the Nexus Scheme. (A PSP may be a member of a local IPS, but not a Participant in the Nexus Scheme.) Where in this Rulebook reference to participation in Nexus Scheme is meant, the term “Nexus Scheme Participant” is used. |

Nexus Scheme Owner | The legal entity that is performing the role of owning, and maintaining, the Nexus Scheme. It is envisaged that this role for Nexus will be performed by the Scheme Organisation . For clarity: A Scheme Owner does not need to be a Financial Institution, nor does it need to be a Payment System Operator. |

Payment Service Providers (PSP) | PSPs include all entities that are eligible to send and receive domestic instant payments through a particular IPS. These could be banks or non-bank financial institutions according to local eligibility criteria.

Each PSP record will contain an indication of whether the PSP is participating in Nexus and therefore is reachable for Nexus payments. |

Source | In the Nexus terminology, Source refers to the initiating side of the Nexus Payment, I.e. the PSP, the IPS, the SAP and the Gateway involved to move the funds to be transmitted to the Payee out of the Payer’s account. |
Source Currency | The currency of the Sender. Also known as “Unit Currency” in ISO 20022 terminology |
Source Gateway (SGW) | The Nexus Gateway deployed by the Source IPS in a Nexus Payment. |
Source IPS | The IPS that sends a Nexus Payment to a Source Gateway. The Nexus Payment is instructed by a Source PSP , to a Source IPS, on behalf of the Payer, who holds a Payment Account at the Source PSP. |
Source Settlement Account Provider | The Source Settlement Account Provider is a member of the Source IPS. The Source PSP sends funds (in the Source Currency) to the FX Provider’s account at the Source Settlement Account Provider. This payment is processed through the Source IPS. |
Tier-based Improvements | FXPs typically offer better exchange rates for larger transactions (so the Recipient receives a larger Destination Currency Amount for a given Source Currency Amount). In Nexus, an FXP can set tiers at which better rates apply. Each tier is defined by a starting threshold value and an improvement that applies to payments above that threshold. |
Unique Payment System (UPS) | An Instant Payment System in a single currency. When an Instant Payment System operates in multiple currencies, each IPS-currency pair is identified as a Unique Payment System. |
Unit Currency | ISO 20022 terminology for Source Currency (the Sender’s currency) |
