onTransferData
onTransferData is the function for the "Transfer Data" Marshall command, which allows for information regarding the transaction to be sent both ways- usually from the device's (VPOS Touch / VPOS Media) end to the peripheral, but can also be sent from the peripheral to the device.
In the void onTransferData(byte[] data) function the data follows the TLV (Tag-Length-Value) format, which consists of:
- Tag (1 byte): Identifies the type of data.
- Length (1 byte): Specifies the length of the value.
- Value (N bytes): Contains the actual data.
The transferred data can be one or more TLV structures, depending on the information being exchanged.
Example
If onTransferData(byte\[] data) receives the following bytes:
5 6 345678 - 5 is the tag for Card BIN
- 6 is the Length, in this case 6 bytes
- 345678 is the value of the First 6 digits of the card number.
The system extracts the Card BIN as "345678".
Tag Descriptions
The table below describes different types of data that can be transferred using this function:
Tag | Tag Name | Data Size | Description |
|---|---|---|---|
| Transaction ID | 8 bytes | Unique identifier for the transaction. |
| "Choose Product" Timeout | 2 bytes | Timeout for the "Choose Product" prompt. |
| Card Type | 1 byte | Identifies the type of card used. More on that bellow. |
| Card Entry Mode | 1 byte | Identifies how the card was entered (swiped, tapped, inserted, etc.). More on that bellow |
| Card BIN | 6 bytes | First 6 digits of the card number (ASCII). |
| Card PAN Hash | 20 bytes | SHA1 hash of the full card PAN (to protect card data). |
| Proprietary Card UID | MiFare- 4, 7, or 10 bytes Magstripe- up to 40 bytes QR- up to 255 bytes | Unique identifier for proprietary cards. QR- numeric values only |
| VMC Authorization Status | 1 byte | Authorization result (0 = Approved, 1 = Declined). |
| COM Status | 1 byte | Communication status between the server and the device. |
| FTL Data | Up to 500 bytes | Raw data transferred at a lower level (MDB Level 3). |
| Create Layout | 4 bytes | Layout creation request. |

| Transfer to BLE | N bytes | Data to be transmitted over Bluetooth/BLE. Related to Nayax EV (internal Nayax request) |
| Select Brand | 8 bytes | Relevant only for the Japanese market! Peripheral->Device: Select the brand to pay instead of having the brand selection screen prior to that. Device->Peripheral: After the pairing process, update the peripheral in bitfield 64 bits of configured brands. |
| Proprietary Card Name | N (up to 500) bytes | Proprietary card Description, arrived from tag 239 from Nayax's server |
| Site ID | 1 Byte | Site ID information from Nayax's servers that arrives in the authorization response |
