4.4 CIE, MTE, POS & SHR: Machine and Point-of-Sale Consumer Entries

4.4 CIE, MTE, POS & SHR: Machine and Point-of-Sale Consumer Entries

Core Principle: Beyond standard consumer direct deposits and internet checkouts, the ACH Network accommodates specialized electronic terminal and home banking payment models through SEC codes CIE, MTE, POS, and SHR. These codes bridge the gap between bank online bill pay portals, Automated Teller Machines (ATMs), merchant retail checkouts, and shared Electronic Funds Transfer (EFT) networks.

1. Customer Initiated Entry (CIE): The Consumer Credit Push

Customer Initiated Entry (CIE) is unique among consumer ACH applications because it operates exclusively as a credit push initiated by a consumer to pay a business biller.

Key Characteristics of CIE

• Credit-Only Nature: CIE is strictly a credit application (Service Class Code 220). It cannot be used to originate debit entries.
• Role Inversion: The consumer's financial institution acts as the ODFI, originating the credit on behalf of its consumer customer. The corporate biller (e.g., utility, telecom, mortgage servicer) is the Receiver, and its bank is the RDFI.
• Addenda Capability: CIE supports one optional payment-related addenda record (Type 7, Code 05) carrying up to 80 characters of remittance information (such as the consumer's biller account number or invoice reference), enabling automated accounts receivable posting at the biller.
• Fraud Risk Profile: Exceptionally low unauthorized return risk because funds are pushed directly by the authenticated consumer through their own financial institution.

2. Machine Transfer Entry (MTE): ATM Electronic Transfers

Machine Transfer Entry (MTE) is used to clear transactions initiated at an Automated Teller Machine (ATM) or specialized financial terminal.

Key Features of MTE

• Bidirectional: Supports both debits (ATM cash withdrawals, terminal fees) and credits (ATM deposits, terminal funds adjustments).
• Terminal Data Requirements: The Entry Detail Record (Type 6) and Addenda Record must carry terminal identification data, including:
  • Terminal Identification Code: A unique alphanumeric code identifying the physical ATM.
  • Terminal Location: The City and State where the ATM is located.
  • Transaction Date: The calendar date on which the consumer operated the terminal.
• Regulation E Compliance: Aligns with Regulation E (§ 1005.9(a)) mandates requiring financial institutions to provide consumers with an electronic terminal receipt disclosing terminal location and transaction identifiers.

3. Point of Sale (POS) Entries: Merchant Card Emulation

Point of Sale (POS) entries are electronic debits or credit adjustments initiated at a merchant's physical payment terminal using a plastic access card (such as a PIN-debit card or merchant-issued payment card).

Operational Specifications for POS

• Card Emulation: Used when a retail merchant routes debit card transactions across the ACH Network rather than through traditional card networks (Visa/Mastercard interchange rails).
• Addenda Records: POS entries support Type 7 Addenda Record (Type Code 02), which conveys terminal location data (Terminal City, Terminal State) and merchant identifiers.
• Dual-Party Processing: POS can include single transactions or debit card cash-back transactions at merchant checkout lines.

4. Shared Network Transaction (SHR): Shared EFT Network Switching

Shared Network Transaction (SHR) entries represent electronic funds transfers initiated at electronic terminals (ATMs or POS devices) that are routed and cleared across shared regional or national EFT network switches (e.g., STAR, NYCE, PULSE, Accel, Cirrus, Plus).

Distinctive Aspects of SHR

• Shared Network Routing: Unlike standard single-terminal POS or MTE entries, SHR entries involve an intermediary shared EFT network switch that performs real-time PIN verification, terminal switching, and network routing before settling the final transaction batch via ACH.
• Addenda Requirements: Like POS and MTE, SHR entries support Type 02 terminal addenda records conveying terminal location and network switch tracking numbers.
