Open-Loop Wallet

An open-loop wallet is a digital wallet that holds a stored balance which can be used widely: to pay many unrelated merchants, to send money to other people, to transfer funds to bank accounts and, in most cases, to withdraw cash. The money in the wallet behaves much like money in a bank account, even though the provider may be a non-bank such as an electronic money institution or mobile money operator. Open-loop wallets are common in markets where mobile wallets serve as everyday payment accounts, including much of Africa and Asia.

The term is used mainly to distinguish such wallets from a closed-loop wallet, which can be used only with the business that issued it, such as a coffee chain's app balance, and from a semi-closed wallet, which works at a defined network of merchants but does not allow cash withdrawal. The underlying idea of an open system is described under open-loop. Some people also use "open-loop wallet" for pass-through wallets such as card-based phone wallets, but those hold card credentials rather than a balance.

A customer loads money into the wallet through a bank transfer, a card payment, cash deposited at an agent or incoming transfers from other users, a process known as wallet top-up. The provider records the balance in its ledger and holds the corresponding funds in safeguarded accounts at banks. The customer can then spend the balance by scanning QR codes, paying online, tapping a linked card or sending money to a phone number.

What makes the wallet open-loop is its connections. It is usually linked to national payment systems, card networks or interoperable switches, so that a user can pay merchants who use other providers, send money to bank accounts and receive salaries or benefits. Cash withdrawals are made at agents, ATMs or bank branches through wallet cash-out services.

Because open-loop wallets function like payment accounts, they are regulated more strictly than closed-loop ones. Typical requirements include:

• Licensing. Providers usually need an e-money, payment institution, mobile money or banking licence, such as authorisation as an electronic money institution in Europe or a stored value facility licence in Hong Kong.
• Customer due diligence. Higher limits and cash-out normally require full identity checks, often organised in tiers by wallet KYC level.
• Limits. Regulators set caps on balances, monthly flows and cash withdrawals, particularly for less verified customers.
• Safeguarding. Customer funds must be protected, for example in segregated bank accounts or trust arrangements, so that they can be returned if the provider fails.
• Interoperability. Some regulators require wallets to connect to national switches so that customers can pay across providers.

India's framework for prepaid payment instruments is a notable example. It distinguishes closed-system and small and full-KYC instruments, allows cash withdrawal only from full-KYC instruments under conditions, and has pushed wallets to interoperate with the Unified Payments Interface and card networks.

Open-loop wallets serve as primary financial accounts for many people without bank accounts, especially through mobile money. They are used for person-to-person transfers, bill payments, merchant payments, receiving remittances from abroad and government payments. Businesses use them to pay workers and suppliers, and some wallets offer savings, credit and insurance through partner banks.

The main differences between wallet types lie in where the balance can be used and how it can leave the system. A closed-loop wallet keeps money within one merchant, which makes it simpler to run and lightly regulated but limits its usefulness. A semi-closed wallet extends use to a group of merchants. An open-loop wallet offers the broadest use, including transfers out to banks and cash, which brings it closest to a bank account in function and in regulation. Wallet interoperability between providers further increases the reach of open-loop wallets.

Open-loop wallets carry risks similar to those of bank accounts. Their ease of transfer and cash-out makes them attractive for money mules and fraud, so providers run transaction monitoring and enforce limits. Agent networks used for cash-in and cash-out can be a weak point for identity checks. Operational outages can cut people off from their main source of money. For customers, protection depends on safeguarding rules, because wallet balances are usually not covered by deposit insurance in the way bank deposits are.
