伪造者的艺术由于流通中的新元被不断追踪和监控，伪造新元的唯一方法是复制一个现有的认证信用棒。这需要一个正余额的认证信用棒，一个用于放置非法信用的相同类型的空认证信用棒(称为空白信用棒)，然后进行伪造+编辑延续检定(时间间隔和阈值见伪造阈值表)。角色每试图伪造等于或少于5000新元，对伪造检定施加1个骰子的负面修正。
Kat o’ Nine Tales有一个带有6000新元的认证信用棒，并决定复制它。她去了当地一家正规银行，得到了一个空白信用棒，然后她把这两个信用棒和她的通讯链链接起来，开始工作。Kat有伪造3 (信用棒伪造+2)和一个等级4的编辑程序，她由于信用棒上的金额获得2个骰子的罚值，所以她掷7个骰子。她决定她的伪造等级将是2，使阈值为48。在20天的时间里，Kat成功地积累了她需要的成功数，现在她有了两根认证信用棒：一根是6000新元的真货，另一根是伪造等级2的6000新元的假货。角色试图将假币转移到线上银行账户或用于购买商品时，使用假币的等级与验证系统的等级(通常为1-6)进行对抗检定。如果赝品赢了，系统就会将其视为真品；如果赝品对抗失败，它立即被标记为伪造，交易中止，并通知地方当局。平局被裁定为利于验证系统。
Kat用她的假信用棒在Aces付了300新元的账单。伪造等级是2级，Aces有一个2级的验证系统。Kat的玩家得到3和6; GM替验证系统掷出2和4。看来Kat的假信用棒通过了这次检查...劇透 - :
THE FORGER’S ART
Since nuyen in circulation are constantly being tracked and monitored, the only way to counterfeit nuyen is to copy an existing certified credstick. This requires a certified credstick with a positive balance, an empty certified credstick (called a blank) of the same type in which to place the illicit cred and an Extended Forgery + Edit Test (see the Forgery Table for Interval and Threshold). For every 5,000 nuyen or part thereof the character is attempting to counterfeit, apply a 1 die penalty to the Forging Test.
Kat o’ Nine Tales has a certified credstick for 6,000¥ and decides to copy it. A visit to her local and above-board bank gets her a blank, and she connects the two credsticks to her commlink and gets to work. Kat has Forgery 3 (Credstick Forgery +2) and a Rating 4 Edit program, and she receives a 2 dice penalty for the amount of nuyen on the credstick, so she rolls seven dice. She decides that the rating of her forgery will be 2, making the threshold 48. In twenty days, Kat manages to accumulate the hits she needs and now has two certified credsticks: one with 6,000¥ in real nuyen, and a Rating 2 forgery with 6,000¥ in fake nuyen.
When the character attempts to transfer the counterfeit nuyen (either to an online bank account or when making a purchase), make an Opposed Test between the rating of the counterfeit nuyen and the rating of the verification system (typically 1–6). If the counterfeit wins, the system accepts it as genuine; if not, it is immediately flagged as counterfeit, the transaction aborts, and local authorities are alerted. Ties are ruled in favor of the verification system.
Kat uses her fake credstick to pay her 300¥ bar tab at Aces. The rating of the forgery is 2, and Aces has a Rating 2 verification system. Rolling for her character, Kat’s player scores a 3 and a 6; the gamemaster rolls a 2 and 4 for the verification system. Looks like Kat’s faux cred passes… this time.

伪造其他货币
除了新元，第六纪还有其他种类的电子货币，黑客也可以伪造它们。典型的例子包括国家货币(加美国美元)和公司券(阿兹特科技公司比索)。这些钱通常比新元更容易伪造，但更难通过验证(验证系统在对抗检定中得到+4DP修正来检测伪造品)。玩家角色还可以制作游戏币，即矩阵游戏中用于购买虚拟装备的货币(小钢珠(译注：pikucredu，柏青哥机使用的代币))；游戏币可以在游戏内用新元购买，但不能在购买后再兑换成新元。
在第六纪，一些非常罕见，落后的地方仍然依靠硬币或纸币等实物交换媒介(参见使用伪造品，第124页，SR4)。
可选规则：伪造SIN或ID伪造系统识别号码(SIN)需要大量的资源，而这是大多数暗影狂奔者所没有的；伪造者必须生成确证数据并将其插入若干政府和企业的数据库，而这些数据库的名称和地址不为公众所知。从事假SIN和假ID交易的中间人与团体已经建立了在发行机构工作的渠道和联系，从而拥有多个进入必要数据库的后门。即便如此，制作高等级的假SIN也是一个冗长而昂贵的过程，而且这也是一个非常私人化的过程，涉及到根据假SIN的等级添加个人信息和生物特征数据的程度。独立的黑客和超链者可以伪造他们自己的SIN，但如果没有人脉和后门，这个过程比买一个假SIN要长得多，也更加困难。GM在允许玩家的黑客角色尝试制造SIN之前应该三思，因为这可能会导致失衡。以下规则由GM自行决定。
创建一个假SIN或假执照(参见合法性，第303页，SR4)需要接入矩阵(通过通讯链，终端，或超链者的先天能力)和伪造+编辑的延续检定(参见伪造表，第95页)。假SIN和假执照有一个从1到6的等级，这决定了它们在验证系统中的表现(参见假身份证，第260页，SR4)。一旦创建，假SIN或执照及其确证数据必须被官方数据库接受，这需要一系列的系统入侵和同节点的骇入+编辑(系统等级，1小时)的对抗检定；由GM决定目标系统的等级，他可以选择一一执行这些对抗检定，或者用骇入+编辑(假SIN等级 x 系统等级，1小时)的延续检定对它们进行快速结算。

OPTIONAL RULE: FORGING SINS AND IDS
Creating a fake system identification number (SIN) requires extensive resources that most shadowrunners just don’t have; the forger must generate and insert corroborating data into a number of government and corporate databases, the names and addresses of which are not available to the general public. The fixers and syndicates who deal in false SINs and IDs have established channels and contacts that work in the issuing institutions and have multiple backdoors into the necessary databanks. Even then it can be a tedious, expensive process to produce a high-rating false SIN, and also a very personal one involving increasing degrees of personal information and biometric data depending on the rating of the fake SIN. Solo hackers and technomancers can forge their own SINs, but without the apparatus of contacts and backdoors in place the process is much longer and more difficult than buying a fake SIN. Gamemasters should think very carefully before allowing their player character hackers to dabble in forging SINs, as it can prove unbalancing. The following rules are for use at the gamemaster’s discretion.
Creating a fake SIN or fake license (see Legality, p. 303, SR4) requires Matrix access (through a commlink, terminal, or a technomancer’s innate ability) and an Extended Forgery + Edit Test (see the Forgery Table, p. 95, for Interval and Threshold). Fake SINs and licenses have a rating from 1 to 6 that determines how well they stand up to verification systems (see Fake ID, p. 260, SR4). Once created, the fake SIN or license and its corroborating data must be accepted by official databases, which requires a series of system intrusions and Hacking + Edit (System, 1 hour) Extended Tests on challenging nodes; the gamemaster decides on the target system ratings and can choose to play these out or summarize them quickly with an Extended Hacking + Edit (Rating of fake SIN x System, 1 hour) Extended Test.
当一个SIN被发现是伪造的，或者因为与之相关的犯罪而不再可用时，就被称为SIN被烧毁了。SIN包含了生物特征和识别数据，如果角色不想它们落入坏人之手，就只能剥离这些负罪数据。购买假SIN(参见转卖商品，第303页，SR4)的中间人和销赃者通常会自动剥离原SIN，但有些角色可能不想冒个人数据被记录的风险。角色可以通过一系列的系统入侵和同节点的入侵+编辑(系统，1小时)的对抗检定来剥离原SIN；由GM决定目标系统的等级，他可以选择一一执行这些对抗检定，或者用骇入+编辑(假SIN等级 x 系统等级，1小时)的延续检定对它们进行快速结算。
当一个SIN被烧毁或剥离时，角色将失去所有线上账户、执照、医疗马车合同、租赁协议、财产契约以及与该SIN相关的合法债务。

BURNT AND STRIPPED SINS
When a SIN is exposed as a fake or is no longer usable because of crimes connected to it, it is said the SIN is burnt. A SIN contains biometric and identifying data that a character doesn’t want to fall into the wrong hands, and can only be stripped of such incriminating data. Fixers and fences who buy fake SINs (see Fencing Goods, p. 303, SR4) typically strip them automatically, but some characters might not want to take the chance that their personal data is recorded first. A character can strip a SIN with a series of system intrusions and Hacking + Edit (System, 1 hour) Tests on challenging nodes; the gamemaster decides the target system ratings and can choose to play these out or summarize them quickly with an Extended Hacking + Edit (Rating of fake SIN x System, 1 hour) Test.
When a SIN is burnt or stripped, the character loses all on-line accounts, licenses, DocWagon contracts, rental agreements, deeds for property, and legal debts tied to that SIN.
一个密钥(参见密钥，第64页)包含一条加密代码，它与一个有效的密码组合在一起，允许用户访问系统。每次访问系统时，加密代码都会递增或打乱，这意味着加密代码会随着每次使用而改变。专业的角色可以制作一个密钥的伪造副本，但他至少需要密钥的原理图和它的固件副本。伪造的密钥(如果正确制作)只能使用一次，并且必须在使用真实密钥之前使用，否则加密代码将无法工作。如果有人使用伪造密钥访问帐户，原始密钥将不再正常工作，蜘蛛或管理员用户将知道帐户的最后一次激活是用伪造密钥完成的。
鉴于这些限制，大多数暗影狂奔者选择窃取或“借用”密钥；特别是更先进的纳米技术密钥和炼金密钥，这需要特殊的设施和设备来制造。

OPTIONAL RULE: FORGING PASSKEYS
A passkey (see Passkeys, p. 64) contains an encrypted code that, combined with a valid passcode, allows a user access to a system. The encrypted code is incremented or scrambled every time it accesses the system, which means the code changes with every use. A dedicated character could forge a copy of a passkey, but it would require at least a schematic of the passkey and a copy of its firmware. The forged passkey (if made correctly) would be good for one use only—and it would have to be used before the actual passkey is used, or the code won’t work. If someone uses a forged passkey to access an account, the original passkey no longer functions correctly, and spiders or admin users will know that the last time the account was activated, it was done with a forged passkey.
Given these limitations, most shadowrunners choose to steal or "borrow" passkeys; especially more advanced nanotech and alchemical passkeys, which require special facilities and equipment to manufacture.
