_transactionManager.Initialize(DeviceAddress, ConnectionType.TCPIP)

• Establishes connection between POS and P630 terminal via TCP/IP

• Must be called first before any other operations

• Creates the communication channel

_transactionManager.Login(OperatorId, Password)

• Logs in the cashier/operator to the terminal

• In NULL mode, password is optional

• Required before starting payment sessions

_transactionManager.StartSession(InvoiceId)

• Creates a payment session with unique invoice ID

• Groups all operations (card capture, payment) under one session

• Must be open before capturing cards or processing payments

_transactionManager.RequestCardData2(
    amount: 10000,  // Maximum expected amount
    tokenRequest: true  // Request ANALYTICS + REUSE tokens
)

Purpose: Capture card BEFORE knowing final price

• Customer taps card once

• Returns card data (brand, last4, BIN, expiry)

• Returns ANALYTICS token → Used to search Diller for member

• Returns REUSE token → Used for future transactions

• Stores card data in terminal memory for later payment

_transactionManager.StartPayment(
    amount: 9000,  // Final discounted amount
    currency: "SEK",
    paymentType: PaymentType.SALE
)

With Early Capture (our implementation):

• Uses card data from step 4 (no re-tap needed)

• Amount can differ from capture amount (discount applied)

• Terminal processes payment with stored card

_transactionManager.EndSession()

• Closes the payment session

• Clears captured card data

• Finalizes the transaction

_transactionManager.Logout()

• Logs out the operator

• Terminal returns to idle state

1. Initialize → Connect to terminal at 192.168.68.123
2. Login → Operator "TEST" logs in
3. StartSession → Session "INV-123" opens
4. RequestCardData2 → Customer taps card (max $100)
   ↓ Returns: { brand: "Visa", last4: "1234", analyticsToken: "ABC..." }
5. [POS searches Diller with token → finds discount]
6. StartPayment → Charge $90 (uses captured card, no re-tap)
   ↓ Returns: { transactionId: "...", authCode: "057652" }
7. EndSession → Close session
8. Logout → Terminal idle

Terminal must have:

Terminal.CardAcquisitionBehaviour = 1

• 0 = Card capture works, but follow-on payment NOT allowed

• 1 = Card capture works, AND payment can use captured card ✅
