The first charge plates: metal tags, department stores and the idea of a card

Hand someone a card today and they will assume it is about money: a balance, a credit line, a way to pay. The earliest ancestors of the card were about something simpler. The first payment cards were not about money at all; they were about remembering who a customer was.

This is a short history of those ancestors, the charge coins and charge plates of department stores, and of the idea that eventually left the store and became the card we know. Dates and details in early payment history are often uncertain, so where accounts differ, we say so.

Buying on account

For centuries, regular customers of local shops bought on account. The shopkeeper knew them, wrote purchases in a book and expected payment at the end of the week or month. The arrangement depended on personal recognition: the shopkeeper knew your face, your family and your habits.

As cities grew and shops became larger, recognition stopped scaling. A department store with hundreds of clerks and thousands of account customers could not rely on every clerk knowing every face. The store needed a way for customers to prove who they were at the counter.

Charge coins

One early answer, appearing in the late nineteenth and early twentieth centuries, was the charge coin: a small metal token, often with a hole for a key ring, stamped with the store's name and a customer account number. A customer showed the coin, the clerk wrote the number on the sales slip, and the purchase was added to the account.

Charge coins did not hold value. They were identifiers, closer to a membership token than to money. Losing one was a nuisance rather than a disaster, though it could be misused by whoever found it.

The charge plate

The next step was the charge plate. In the late 1920s, a company called Farrington Manufacturing introduced the Charga-Plate, a small rectangular metal plate embossed with the customer's name and address, usually carried in a leather sleeve. Stores in several American cities adopted it in the following decades.

The embossing mattered. The plate could be placed in a machine that pressed the raised characters onto a sales slip, copying the customer's details accurately and quickly. That removed handwriting errors and sped up the counter.

What the plates did, and did not do

Charge plates solved identification and transcription. They did not solve trust. The store still decided who could have an account and how much they could buy. Lost plates could still be misused until the store was told. And each plate worked at only one store or a small group of stores.

That last limit was the important one. A shopper with accounts at five stores carried five plates or coins, each tied to a separate relationship.

Leaving the store

The idea that changed this was simple: a single card accepted by many merchants, with a third party standing behind the payment. Accounts of the first such card usually begin with Diners Club in 1950, created to let members pay at participating restaurants and settle one bill each month. The often-told story of a forgotten wallet at a dinner is probably more legend than history, but the business model was real.

The card was made of cardboard at first. What made it new was not the material but the arrangement: the card company paid the restaurant, charged the restaurant a fee, and billed the member.

Bank cards

Within a decade, banks entered. In the late 1950s, a large American bank mailed unsolicited credit cards to residents of one city, testing a revolving credit card that many merchants would accept. The experiment was chaotic, with losses and fraud, but the model survived and later grew into one of the major card networks. Other banks formed associations that became the other major network.

By then, the card had become three things at once: an identifier, like the charge coin; a way to copy details accurately, like the charge plate; and a promise from a third party that the merchant would be paid.

The parts that survived

Several features of modern cards trace straight back to these early objects:

• Embossed numbers, once essential for imprinting machines, survived on physical cards for decades after electronic terminals arrived.
• An account number at the center, identifying the customer to the issuer.
• A third party behind the payment, now the issuer and network described in the cast behind every card payment.
• Monthly settlement, inherited from store accounts.

What changed completely

Modern cards differ in ways the charge plate never imagined: instant authorization, worldwide acceptance, chips and tokens, and cards that exist only as data. A virtual card has no metal, no plastic and no embossing, yet it still does the charge coin's original job. It tells a merchant, through the network, who stands behind this payment.

Recognition, then and now

The thread running through this history is recognition. The local shopkeeper recognized faces. The department store recognized a coin or a plate. The card network recognizes a number and its issuer. Today, systems also recognize devices, behavior and codes from authenticator apps.

Each step traded personal knowledge for a token that could be checked by strangers. Each step also created a new way to cheat: a found coin, a stolen plate, a copied number. The history of cards is partly a history of trying to close those gaps, which we follow further in our long read on the move from carbon copies to chips.

Our small place in the story

Our cards are virtual cards, issued only after a person checks the payment behind them. The process page shows the steps. In a sense, they return to an old idea: the card holds what was paid in, nothing more, and the merchant is paid because the money is already there.

Questions people ask

Was the charge plate a credit card?

Not in the modern sense. It identified a customer with an account at a particular store, which extended credit on its own terms.

Why were card numbers embossed?

So that imprinting machines could copy them onto paper slips. The feature outlived the machines on many physical cards.

Who invented the credit card?

There is no single inventor. The card emerged from store accounts, charge tokens, travel and entertainment cards and bank experiments over several decades.
