Heartland Payment Systems Inc.'s E3 magnetic stripe reader has been validated to minimize certain payment security compliance requirements for point of sale developers, the company said Monday.

The Princeton, N.J., payments processor said that Coalfire Systems, a qualified security assessor for PCI issues, validated its reader's utility for averting work needed to satisfy the Payment Application Data Security Standard, or PA-DSS.

That standard is intended to prevent the use of nonsecure payment applications that store magnetic stripe, PIN and other payment card data.

Heartland's E3 wedge device prevents plaintext data from being available to payment applications, the company said in a press release.

Coalfire's assessment also determined that the product can reduce PCI compliance work for merchants by up to 69%.
