Pilot program now forming

ANTIPHON^™

Bank details changed? Call back first. Seal the proof.

Antiphon is a plug-in for title, escrow and settlement companies. Before money goes to new or changed bank details, your staff call the payee back at a contact you had on file before the request came in. Each step is sealed. Your payment system gets a sealed pass or fail to act on.

How the callback works

The callback runs inside your own system. Staff follow the same steps every time.

Keep trusted contacts on file

Add each payee’s phone or email before any change request. Say where it came from, such as a prior signed contract or your own records. It is sealed with the server clock.

Log the request

Log the change of payment details or the payment to send. Record how it came in and the contact it came from. Type only the last 4 digits of bank numbers.

Call back on a contact from before

Staff pick a trusted contact from the list. Antiphon will not seal a callback to a contact added after the request, or to the number or email given in the request.

Confirm each detail

Read each detail to the payee: name, account last 4, routing last 4 and amount. Mark each one confirmed, denied or not asked. Any denied detail fails the callback.

Get a second approval

If your company turns it on, a second staff member approves or rejects. The person who made the call cannot approve it.

Send the payee a receipt

After a verified callback, staff make a receipt link. The payee answers “Yes, that was me” or “I did not get a call.”

Run the release check

Right before release, run the check. It returns a sealed pass or fail with the reasons. A dispute from the payee makes it fail until a new verified callback is sealed.

Keep the proof packet

Issue a sealed proof packet with every step in order. Print it, save it as PDF, or save the packet file.

Antiphon does not move, hold or release money. It hands your payment system a sealed pass or fail. Your system decides what to do with it.

What each person sees

Each person sees only what their part needs.

Staff

The callback panel in your own system

Where the request stands, and why release would fail right now.
The payee’s trusted contacts, with any that cannot be used for this request marked and explained.
A step-by-step callback form, then the release check and its history.

Second approver

The verified callback, ready to review

Approve or reject. A rejection needs a note.
One decision per person for each callback.
A rejection makes the release check fail.

Payee

A receipt page, no sign-in

When their details were verified by call, and by which company.
Last 4 digits only, the masked number called and where it came from, and who answered.
Never your notes or the full number.

Their two answers:
Yes, that was meI did not get a call

Your payment system

A sealed result after every step

The panel tells your system each time a new step is sealed.
The release check returns pass or fail with the reasons.
Your system holds or releases. Antiphon never does.

Why a sealed record matters

When a payment is questioned, you need to show what was done, when, and by whom.

Every step is sealedEach entry gets the server’s time and is linked to the one before it. If anything changes later, the check fails.

The number was on file firstThe record shows which on-file contact was called, where it came from, and that it was sealed before the request came in.

Every release check countsEach check is sealed, pass or fail. The record shows whether the payer checked before releasing.

The payee has a sayThe payee’s “Yes, that was me” or “I did not get a call” is sealed in the same record.

Anyone can check itA public verify page checks a proof packet file in the browser. The file is not uploaded. It also checks a verification code or a receipt.

Bank numbers stay outOnly the last 4 digits of account and routing numbers are kept. Long runs of digits are refused in free-text boxes.

A seal proves what staff recorded, when, with which on-file contact, and that the record has not changed since. It cannot prove who was on the other end of the call.

Who it’s for

Title companies

Payments to sellers, borrowers and vendors when bank details change.

Escrow companies

A sealed callback before funds go to new or changed instructions.

Settlement companies

One record of the callback, the approval and the release check for each request.

The software they use

Place the callback panel inside your app. Your app opens it with the request ID and gets the sealed result back.

Antiphon is licensed, never sold.
