PPS RFID Laundry Tag

A rigid HF button for item-level identification

The PPS laundry tag is a moulded button or disc that encloses an HF chip and antenna. It is sewn on or held in a pocket or bag, and its identifier links each linen or uniform item to a record in your laundry software. The photos show buttons in several diameters, some with two fixing holes; the quotation and the sample confirm the offered model’s diameter, thickness and hole arrangement. The PPS material alone does not establish wash life.

Specification

ICODE SLIX or SLIX2

Both are NXP HF chips for ISO/IEC 15693 and ISO/IEC 18000-3. Each has a 64-bit unique identifier (UID) that is set in production and cannot be changed, and an anti-collision function that lets a reader address several tags in its field. They differ in memory and security features:

NXP marks ICODE SLIX as not recommended for new designs and names ICODE SLIX2 (for the 23.5 pF version) and ICODE 3 as its successors. This page covers SLIX and SLIX2; specify SLIX2 for a new programme unless the installed system requires SLIX. If your software writes data to the tag, uses passwords or checks originality, name those SLIX2 features and test them on the sample with your reader. Confirm the chip named in the quotation for each batch. Chip data: NXP ICODE SLIX and ICODE SLIX2 data sheets. A chip’s features do not establish the finished tag’s read distance or wash life.

HF readers and read points

The reader must support ISO/IEC 15693; a reader built only for ISO/IEC 14443 cards is not enough, although both work at 13.56 MHz. Anti-collision is a chip feature, not a finished-tag throughput rating: measure the proposed tag at each checkpoint with your reader and antenna, wet and dry, before setting a load or distance target. A laundry that runs UHF inventory should evaluate the textile or silicone UHF tags; the textile page compares all three formats.

Wash limits to confirm for a PPS button

In real laundry use the PPS button has handled temperatures up to 180 °C. That is field experience, not a guaranteed limit: it names no dwell time, pressure or process stage and does not transfer to the textile or silicone tags, so check it on buttons run through your line. The laundry tracking guide sets out the full wash-process specification and, in its test-record section, the record to keep for that trial. On a rigid button, the points that differ are:

• Pressing and ironing: the press, ironer or tunnel-finisher temperatures and times the button passes through.
• Fixing: stitches through the fixing holes or a closed pocket, never through the moulded RFID area; inspect the fixing after extraction and finishing.
• Failure criteria: a cracked or deformed button or a lost fixing counts, as does a missed read at the agreed reader settings.

Proud Tek makes the PPS tags in its Shenzhen factory. Tell us your reader, the chip your system expects, the items and the wash process through the contact page or the sample button; the quotation names the offered chip, button size and any encoding or laser marking.
