A MACU (multiple Access Identity Module) is the bank's special phone line meant for multiple user authentication. It has a special code which you enter when you pick up the phone. For each user, you will be given a different MACU that corresponds with a different ten-digit account number. In simple terms, each time you pick up the phone and dial an extension, you are authenticating yourself to that particular bank. It is a rather complicated process, but here is how you accomplish it:
There are several ways that different banks use different macu routing numbers. For example, some banks use their own dedicated internal system to implement their MACU system. Other banks use dedicated private lines connected to a large telecom switch and router. Still other banks connect to public switched phone networks. It really depends on where your call comes from, but the point is the same: every time you pick up the phone, you are authenticating yourself to the particular bank. So, when you want to make a call to another person, you dial the number that corresponds to your bank account.
What does this have to do with MACU numbers? Well, if you think about it, you have probably had a friend or family member dial your credit union or other banking service number at least once. Maybe they made a purchase or even borrowed money from the business you work for. Before you answer the call, you have to identify yourself.
Macu Routing Number System Benefits
In the past, you had to punch in your own MACU (Multi Access Number). After a while, you would add more digits, but you could only have up to nine digits. It was either that or you were going to have to go to the bank and punch in your own digits. The process was tedious and very time consuming. You also had to remember what nine digits you used for different services.
That process has been simplified. Today, when you dial the number for your macu routing numbers, you simply hit enter and then wait for the number to be assigned to you. Instead of having to punch in your own MACU, you simply use the number the company uses for their banks. However, some banks still use their own MACU (Master Code Number) which is different from the one used by the credit unions.
This means that each time you make a call to a different branch, your caller ID displays the MACU number for the bank account holder's bank. For many banks, this has eliminated long lines at customer service desks and has helped to cut down on customer complaints. The banks also save money by using only one number for multiple routing numbers. In addition, customers have the option of making calls to multiple banks and receiving the same personalized greeting each time.
Another advantage to using an AA Ajax system is that it can be used for direct deposits. Many companies are now making electronic deposits into their bank accounts. This makes it easier to pay employees, rent or mortgage money, and more. Instead of having to print out checks, an electronic deposit can be processed immediately. As an added benefit, many of these electronic payments can be deposited directly into your checking account.
For those who are unfamiliar with electronic payments, an example would be direct deposit into a bank account. When you enter the amount into your regular checking account, it is automatically transferred into your checking account. If you choose to receive an electronic payment instead, all you do is enter the amount you wish to transfer. When it is time to sign the check, it can be done from the same page where you signed the check in the first place. The advantage to this system is that if you are transferring large amounts of money, it can be done very quickly and easily, and usually automatically, making electronic transfers a good option for business owners who need to make direct deposits.
