What are the design requirements for membership cards?
    Membership card design must meet eight requirements, and none of these requirements can be omitted.

Requirement 1: Signage
    A logo refers to your organization's LOGO. If you don't know what a LOGO is, you can look up relevant information yourself. This is especially important because a LOGO is a mark of a different company. Generally, every company has its own logo. For example, when we only make card networks, we have a logo that looks like a key.

Requirement 2: Name of the issuing unit
    This means finding the issuing company for our membership cards. Simply put, the name of the issuing company is written on the card issuer. For example, if we only make a batch of membership cards on Card Network, then write the slogan next to our card network.

Requirement 3: Card name
    This is easier to understand. It depends on the name of the card you issue. For example, if we only make cards for card networking, we might name it 'Only Card Membership Card.' Of course, this is a joke—it means the card is yours, and you can name it however you like.

Requirement 4: Numbering
    It refers to the number on each membership card, just like each person's ID card. For example, the first card number is 1, and the second card number is 2. This is the number, which you can design yourself.

Requirement 5: Signature slip
    The signature slip is usually only on the back of the card and can sign the names of all cardholders. Most cards use it on the same page.

Requirement 6: Computer interface
    This computer interface generally refers to barcode cards, magnetic stripe cards, and contact chip cards. Barcodes can be divided into 13 barcodes, 28 barcodes, etc., and each barcode requires different computers; The magnetic stripes are the same; the writing track is different, so the machine requirements differ; There are even more contact chip cards, so we need to know the computer interface as well.

Requirement 7: Instructions for use
    This means that what needs to be told to the user about this card is usually written on the back of the card, roughly explaining how to use the card, important precautions, and how to contact the issuer.

Requirement 8: Contact information of the issuer
    The issuer's contact information can include a phone number, fax, email, address, website, MSN, mobile number, and anything else that can be reached can be designed on the card.
