For the sake of explaining, we are going to make a configuration with 3 acquirers :

• Amex.

  • Acquirer Number (0xDF1B) : 01

  • Acquirer Identifier (0x9F01) : 0000001

  • Merchant Identifier (0x9F16) : 4D65726368414D4558303030303031 (MerchAMEX000001)

  • Terminal Identification (0x9F1C) : 416D657841435131 (AmexACQ1)

• Cheap Bank for low value (under 25 euros)

  • Acquirer Number (0xDF1B) : 02

  • Acquirer Identifier (0x9F01) : 0000002

  • Merchant Identifier (0x9F16) : 4D6572636843686561703030303031 (MerchCheap00001)

  • Terminal Identification (0x9F1C) : 4368656170414351 (CheapACQ)

• Great Bank for high value (over 25 euros)

  • Acquirer Number (0xDF1B) : 03

  • Acquirer Identifier (0x9F01) : 0000003

  • Terminal Identification (0x9F1C) : 4772656174414351 (GreatACQ)

They are all going to point to the same host (ID : ACQUIRER001)

Template E2 (Application Profile Selection Table)

For the low-value vs high-value acquirers, we must configure correctly the E2 profiles to point to the correct profiles with the right acquirer parameters

...

Amex Entry does not need to have low-value vs high-value because it points to the same acquirer.

Template E6 (Application Profile Table)

We are going to make one application profile for each product and put the low-value acquirer information on it.

We are going to make an additional application profile for each product, reference the low-value, and only overload the Acquirer Number, Acquirer Identifier, Merchant Identifier, and Terminal Identifier.
