# ActiveMerchant::Billing::Check

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. Currently, only `BraintreeGateway` supports the Check object.

### Attributes

account_holder_type[RW]
account_number[RW]
account_type[RW]
first_name[RW]
institution_number[RW]

Used for Canadian bank accounts

last_name[RW]
number[RW]
routing_number[RW]
transit_number[RW]

Used for Canadian bank accounts

valid_routing_number?() click to toggle source

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

    # File lib/active_merchant/billing/check.rb, line 52
    def valid_routing_number?
      d = routing_number.to_s.split('').map(&:to_i).select { |d| (0..9).include?(d) }
      case d.size
        when 9 then
          checksum = ((3 * (d[0] + d[3] + d[6])) +
                      (7 * (d[1] + d[4] + d[7])) +
                           (d[2] + d[5] + d[8])) % 10
          case checksum
            when 0 then true
