Could one card or bank account fund several wallets?¶

Yes. One card or bank account can be linked to several online wallets or payment accounts.

Avoid the dangerous assumption¶

The dangerous assumption is that each funded wallet must belong to the cardholder or bank-account holder.

A family may use one card across several accounts. A business may fund multiple employee or merchant wallets.

An offender may also add a compromised card or account to several wallets to spread activity or avoid controls.

Relevant records may include wallet account IDs, dates linked, verification events, devices, IP addresses, transaction references and funding amounts.

The card issuer or bank may show several payments to the same provider without revealing which internal wallet received them.

The payment provider may be needed to map each external charge or transfer to the specific wallet account and internal transaction.

Preserve the bank or card transaction reference, provider descriptor, amount, timestamp and masked account details.

Ask the provider which wallet received the funding and what account, device and session created the link.

Compare all wallets connected to the same source for common devices, contact details, recipients and withdrawal destinations.

Do not assume common funding proves common control. Legitimate shared use is possible.

Equally, do not ignore a pattern where one compromised source funds several newly created accounts.

When reporting, distinguish the funding account, each wallet account and the evidence of common or separate control.

Operational takeaway¶

Map every wallet linked to the same funding source and use provider, device and transaction evidence to determine whether the accounts share a controller.
