Sir, If missing transaction in POS is duplicated or merchant is fraud and added without customer intervention then it would be a loss for customer right? Then How to handle this situation since already Batch in Acquirer is favoring the merchant by adding 11th transaction.

Sir i have doubt, The PIN is decrypted 1.At Acquirer 2.At Payment System Before reaching to the Issuer. Is it not a security breach. Since PIN is revealed to merchant and acquirer and PS?

Really great !!. Thanks Ramash.. you are helping so many..from this informative information

Domain Podium, Great video. A few things to add: (a) QR Codes are of two types viz. Merchant Presented or Customer Presented. (b) Global bodies like EMVCo are helping to unify the fragmented ecosystem with a QR Code standard that makes globally interoperable QR Codes possible. VISA's mVISA and Mastercard's MasterPass are EMVCo compliant. (c) While your focus was on Card Payments QR Codes, there are also Account to Account payment QR Codes.

Please provide the whatsApp group link, I Will really happy to join this community.

Provide an real life example of PUSH payment please.

Thrilling ❤ god bless you sir amazing explanation

Your explanation is Everyone to understand

Please don't use the background music. It is irritating

What happens if the merchant is using a External vendor device (eg Pinelabs) who route the transactions to all banks nd the merchant doesn’t use bank devices in this case?

These keys are generated only in the case of debit? Because we don’t use pin for credit. What is the scenario for credit?

Goes in and out of focus too much!

in case of AFD , There is also one configuration possible . Authorization Message :- Upon Receiving 1.00 USD or EUR in Field DE 004 of Request Message , Acquirer can reserve some amount and send it to Issuer . Completion Message : When the Actual Amount is received , it is send to Issuer and Rest of the Amount from Cardholders Account is made avaliable again For Example - if in the Authorization Message Amount Reserved is 150 USD or EUR and Actual Amount in Completion Message is less than 150 , then Rest of the Amount is made avaliable again for Cardholder Use .

Car rental and lodging merchants must follow industry practices COF framework. Also DE25 has been discarded by MC. To know preauth- MTI 0100, DE22.1=81/10, DE3.1= 00, DE61.7=4, DE61.4=5/4 (MIT) .

Hi Ramesh, Could you please make a video on GPP classic/sp, it will help us in interview... Thanks for all your videos......

Thank you so much. Currently I'm working in card payment industry. I want to learn more in this field and get certification. Is there any courses available in mumbai ?

Very good explanation Sir

Thanks so much Ramesh and Vivek. I would like to know what happens in case of a refund for DCC transaction. Does it mean the Cardholder billing amount will remain the same as in the original sale txn even if the exchange rate fluctuates? Also, in the case of normal cross-border txn, are there possibilities of the refund txn being applied a different rate? What is the benefit of DCC to the acquirer?

Awesome. Is issuer allowed to decline DCC transactions? Because when I was choosing to pay in my home currency, the transaction was getting declined. But when I paid in merchant currency the transaction was successful.

Hi Sir, How the payment conversion can be done ?

Thank you my friend!!!! You deserve the heaven for such a clear and.complete explanation

Sir how to contact you?

When a merchant initiates a standalone refund without the original authorization code, the fees related to that transaction will be refunded to customer ? example: - Transaction amount: 10 USD - Markup fee: 1 AED (approximately 0.27 USD) If the merchant initiates a 10 USD standalone refund without the original authorization code, what will happen in such scenario ?
