expDate or routing number.
For ACH transactions, processing in the US, two fields are used: routing number and account number. For ACH (EFT) transactions, processing in Canada, three fields are required: three-digit institution number, five-digit branch number, and account number. For processing purposes of Canadian ACH, the institution number and branch number are combined in a single routing number value using the rules below.

The Canadian routing number is comprised of three parts: a leading zero (0), three-digit institution number (YYY) and five-digit branch number (XXXXX), which go respectively all together with no dashes: 0YYYXXXX. Please, note that the institution number (YYY) should never be all zeros (000).
The XXXXX-YYY format with a dash between the branch number and the institution number is only valid for paper-type transactions, such as checks. Thus, if a check reads XXXXX-YYY, the corresponding EFT code will be 0YYYXXXXX.

When transaction is associated with a credit card, the field contains encoded card's expiration date. When transaction is associated with a bank account, the field contains encoded account's routing number.

When Tokenization is not available and encryption is allowed on the server, the field contains encrypted credit card number or bank account number.
Note: if encryption is not allowed on the server and tokenization is not properly configured, transactions will fail and will not be either processed or persisted.
