What does carding mean?
Carding names two quite distinct activities that share only their form. Its oldest sense belongs to textiles: carding is the process of drawing raw fibres such as wool or cotton through wire-toothed brushes called cards, or through a carding machine, in order to untangle, clean and parallelise them ready for spinning into yarn. It was once a labour-intensive household chore and later became a mechanised cornerstone of the industrial textile trade, giving us terms like carding machine and carding mill. In recent decades a second, unrelated meaning has emerged in criminal slang: carding refers to the theft, sale and fraudulent exploitation of credit card data, typically discussed on underground forums. The register therefore depends heavily on context — neutral and technical in a mill, decidedly sinister in a police report.
nounThe process of combing and cleaning raw fibres such as wool or cotton to align them before spinning. In a separate modern sense, the illicit trade in stolen credit card data and its fraudulent use.
- The textile process of disentangling, cleaning and intermixing fibres using cards or a carding machine.
- The illegal activity of trading in and exploiting stolen credit card information.
"The raw fleece went through carding before it was spun into yarn."
"Carding opens and aligns the wool fibres so they can be drawn into a continuous sliver."
"Police dismantled an online forum dedicated to carding and identity theft."
Before machines did it, every thread in history began with carding — brushing tangled wool until it lay straight enough to spin.

Etymology of carding
The word derives from 'card', from Latin 'charta' (a leaf of paper) via Late Latin 'cardus'? — more reliably, it comes through Old Provençal 'cardar' from Late Latin 'cardare', related to Latin 'carduus', meaning thistle, since dried teasels and thistle heads were originally used to comb fibres. The noun 'carding' arose as the verbal noun of this verb, attested in English by the late Middle Ages alongside the medieval wool trade.

How carding is actually used
In everyday modern usage outside the textile industry, 'carding' increasingly refers to credit-card fraud, especially in cybersecurity contexts. The fibre-combing sense is technical and largely confined to wool and cotton manufacturing.
Easily confused with carding
Charding is not an established English word, so confusion is rare; 'carding' should instead be distinguished from 'card', which can also mean a playing card or to phone someone.
Cord is a thick string or rope, whereas carding is the combing of fibres — the words merely sound somewhat alike.
