The Petersfield, Hampshire-based company has invested £100,000 in a DS100 mail inserting system from Pitney Bowes.
According to ID Data Cards business development director John Cooke, the machine should pay for itself in just six months.
He said: "Combined with the launch of our one-piece mailer we possess the capability to handle the precise mailing needs of our customers.
"In the past 12 months, we have experienced considerable demand for end-to-end card solutions, so the mailer will provide us with the capacity to undertake high-volume requirements in a fast and cost-effective manner."
The mailer can handle up to 12,000 items per hour and ID Data Cards expects it to provide a "very low cost per mail piece". It will handle a number of formats including design, manufacturing, personalisation and mailing.
Tall Group has a turnover of around £16m and employs more than 200 staff across its businesses, which include Tall Security Print and Checkprint.
