# BillingMethodFacts

object type

The stored off-session method's wire-readable facts. The three fields live and die together (attach stamps, detach removes whole).

## Fields

| Field | Type | Notes |

| `brand` | [String](/types/#scalars) `String!` | The card network (visa \| mastercard \| …) — the processor's word. |
| `last4` | [String](/types/#scalars) `String!` | The card's last four digits. |
| `attachedAt` | [String](/types/#scalars) `String!` | When the method attached (UTC ISO). |
