Overview

The Check object is a plain old Ruby object, similar to CreditCard. It supports validation of necessary attributes such as checkholder’s name, routing and account numbers, but it is not backed by any database.

You may use Check in place of CreditCard with any gateway that supports it.

#valid_routing_number? ⇒ Boolean

Routing numbers may be validated by calculating a checksum and dividing it by 10. The formula is:

(3(d1 + d4 + d7) + 7(d2 + d5 + d8) + 1(d3 + d6 + d9))mod 10 = 0

See en.wikipedia.org/wiki/Routing_transit_number#Internal_checksums

Returns:

  • (Boolean)
